2) ……………….: Base year prices :: P₁ : Current year prices
3) Laaspeyre’s index : ………………. :: Paasches index : Current year quantities
4) ……………….: Single variable :: Composite index: Group of variables
Answers:

1. Quantity Index
2. P₀
3. Base year quantity
4. Univariate Index

3. Solve the following:

Question 1.
Calculate Price Index number from the given data:

Answer:

Commodity	Base Year price 2005 (P0)	Current Year price 2006 (P1)
A	6	8
B	16	18
C	24	28
D	4	6
Total	Σp0 = 50	Σp1 = 60

Steps:
Add the price of base year (p₀)
Add the price of current year (p₁)
P₀₁ = \(\frac{\Sigma p_{1}}{\Sigma p_{0}}\) x 100
= \(\frac{60}{50}\) x 100
= 120
Hence P₀₁ = 120

Question 2.
Calculate Quantity Index number from the given data:

Answer:

Commodity	Base Year Qty.(q0)	Current Year Qty. (p1)
P	170	90
Q	150	70
R	100	75
S	195	150
T	205	95
Total	Σp0 = 820	Σp1 = 480

Steps : Add quantities of base year (q0).
Add quantities of current year (q ).
Q₀₁ = \(\frac{\Sigma q_{1}}{\Sigma q_{0}}\) x 100
= \(\frac{480}{820}\) x 100
= 58.53
Hence, Q₀₁ = 58.53
As quantity in the current year has fallen Q₀₁ is less than loo.

Question 3.
Calculate Value Index number from the given data:

Answer:
Steps:
(1) Formula used for Value Index Number
= V₀₁ = Zpq x 100
(2) We find product of prices and their respective quantities of the different commodities for the base year to derive p0q0, then take the sum total of the products to derive Zp0q0.
(3) Similarly, find the product of prices and their respective quantities for the current year to derive p1q1, then take the sum total of the products to derive p₁q₁.

Value Index Number = \(\frac{\Sigma p_{1} q_{1}}{\Sigma p_{0} q_{0}}\) x 100
= \(\frac{6,540}{1,890}\) x 100
= 346.03
Value Index Number = 346.03

Question 4.
Calculate Laaspeyre’s and Paasche’s index from the given dala:

Answer:
I’m 7
Price Index P₀₁ = \(\frac{\Sigma p_{1}}{\Sigma p_{0}}\) x 100
= \(\frac{42}{40}\) x 100
= 105
Hence, P₀₁ = 105

4. Distinguish between:

(c) He is a German Economist who gave the method of calculating Index Number in the year 1871.      .	(c) He is a German Statistician who devised the method of calculating Index Number in the year 1874.

5. State with reasons whether you agree or disagree with the following statements:

Question 1.
Index numbers measure changes in the price level only.
Answer:
No, I do not agree with this statement.

• Index numbers are statistical devices which are used to measure changes in some quantities which cannot be measured directly.
• It shows the changes in the variables like price, quantity of output, exports, standard of living, cost of living, stock markets, etc.
• Index numbers are like economic barometers, measuring changes in variables over time with respect to a chosen base year.
• Hence, it is not right to say Index Numbers measures changes in price only.

Question 2.
Index numbers are free from limitations.
Answer:
No, I do not agree with this statement.
Although index numbers are very useful in business and industry, they suffer from following limitation:

• Bias in the data: If the data is not collected properly, we may not get proper index numbers.
• Based on samples : If the samples are not collected properly, there may be error in index number calculations.
• Misuse of index number : We compare the index numbers with the base year, but if a businessman chooses a base year in which profits are high and show that his profits are falling now.
• Changes in the economy : In long run habits, tastes, etc of people may change, so it is difficult to include all such changes in index number.
  Hence, it is not right to say that index numbers are free from limitations.

Question 3.
Index numbers can be constructed without the base year.
Answer:
No, I do not agree with this statement.
Index numbers can be constructed without the base year because :

• Index Numbers are the tools for measuring J the changes in the magnitude of a variable or a group of variables over time with respect to a chosen year.
• Prices of some goods may increase and of other may decrease during the two periods. Index numbers solves this problem by taking the average change.
• For example, to know cost of living of people in general in India, Government chooses a base year 2010 which is taken as 100. Then  cost of living is calculated in 2019 which may be 140.
• This difference of 40(140-100) shows that cost of living in India has increased by 40% ( since 2010.
  Hence, Index Numbers cannot be constructed – without the base year.

6. Answer the following:

Question 1.
Explain the features of index numbers.
Answer:
Features of Index Numbers :

• Index numbers are a specialised form of averages.
• They are expressed in percentage form without using a percentage sign.
• The year for which index number is being prepared is the current year.
• The year from which index number is being prepared is called the base year which is ? always taken as 100.
• They are used in measuring the changes ( in magnitudes which cannot be measured directly.
• The formula used for Price Index Number = \(\frac { Total price of the current year }{ Total price of the base year }\) x 100
• They are considered as barometer of economic activity.
• Index number which is calculated from a single variable is called “univariate index” and which is constructed from a group of variables is called a “composite index”.

Question 2.
Explain the significance of index numbers in economics
Answer:
Index numbers are significant tools of economic analysis in the following ways:

(1) Help in formulating Policies : Index numbers help the government and business organisations in framing their suitable economic policies for agriculture and industrial sector, wage and dearness allowance policies, etc.

(2) Help in the study of Trends and Tendencies : Index numbers study the relative changes in the level of phenomenon of different periods of time, so they can be used to predict future events. The economists can study the general trends of changes in price levels, agricultural and industrial production, export, imports, etc.

(3) Economic Barometer : Just as barometer is used to measure atmospheric pressure, index numbers measure the level of economic and business behaviour. They are very important for an economist, businessman, planners, policy makers, etc.

(4) Helps in Measurement of Inflation :
It helps the government to take measures against inflation by giving additional D.A. to the employees on the basis of Dearness Index.

(5) Help to adjust National Income : By comparing current year’s national product prices with the base year’s prices, the Domestic Product (GDP) produced. Hence, this shows changes in real national income.

(6) To present Financial Data in Real Income : Index numbers are used to adjust price change, wage change, etc. Thus deflating helps to present the financial data at constant prices.
(Note: Deflating means to make adjustments in the original data)

(7) Helps in determining Depreciation
Cost: The price index helps in determining the depreciation cost of durable goods. At the time of inflation, it is useful to know the original cost of the commodities.

7. Answer in detail:

Question 1.
Explain the steps involved in the construction of index numbers.
Answer:
Steps involved in the construction of j index numbers are as follows :
1. Purpose of an Index Number : Before constructing an index number, one must know the purpose for which the index number is constructed. E.g. for the whole c sale price or retail price or for agricultural – output, etc.

2. Selection of a Base Year : It is important to select a base year against which comparisons are made. So base year or reference year should be
(i) a recent year and not a distant past.
(ii) it should be normal and free from natural calamities, war, etc.

3. Selection of Commodities: When the cost c of living index number of the middle class jj families is to be constructed, the items that are used by middle class families in everyday life should be included and items like big cars, AC’s, etc. should not be included.

4. Selection of Prices : Prices differ from city to city and even from shop to shop in the same city. Hence, we should take a few standard shops from where middle class families buy goods and take the average of the prices of goods sold by them. Otherwise index number
constructed may be misleading.

5. Selection of suitable Average : An ; index number is a special kind of average, Generally arithmetic mean is commonly ? used for construction of index number as it is simple to calculate.

6. Selection of Formula : Number of formulae can be used for construction, of index numbers. Economists have to decide which formula to use for the construction of a particular index number.

7. Assigning proper Weights : Weights refer to the relative importance of different items in the construction of an index number. ( Weights may either be quantity weights (q) or value weights (p). All weights may not be equally important. Therefore, by s assigning specific weights better result can be obtained.

5. Answer the following:

Question 1.
Explain the features of Oligopoly.
Answer:
The term Oligopoly is derived from the Greek words ‘Oligo’ which means few and ‘Poly’ which means sellers. Hence, following are its features –

1. Many buyers and few sellers : There are many buyers and a few sellers or firms (may be five or six) who dominate the market and have major control over the price of a product.

2. Interdependence : Since the number of firms are less, any change in price, output, product etc. by one firm will affect the rival firms and will force them to change their price, output, etc. E.g. In case of Coke and Pepsi in soft drink market.

3. Selling cost or advertising : Each firm in order to sell more of its product takes aggressive steps to advertise or through free samples. This helps them to capture larger sales.

4. Barrier to entry : The firm can easily exit from the industry whenever it wants, but to enter a new industry it has certain entry barriers like government license, patent right, etc.

5. Uncertainty : There is a great uncertainty in this market if the rival firms join hands and may try to fight each other.

6. Lack of Uniformity : The firms may produce either homogeneous or differentiated products. Eg. In automobile industry, Maruti, Indica are examples of differentiated product but cooking gas of Bharat Petroleum and Hindustan Petroleum are examples of homogeneous product or pure oligopoly.

Question 2.
Explain the types of Monopoly.
Answer:
There are different types of monopoly as analysed below:

(1) Natural Monopoly : A natural monopoly arises when a particular type of natural resource is located in a particular region like petrol or crude oil in Gulf countries. Also natural advantages such as good location, business reputation, age – old establishment s etc., confer natural monopoly. Similarly, many professional skills, natural talents give monopoly power. E.g. A singer or actor has monopoly of his skill, talent.

(2) Legal Monopoly : Legal monopolies are those monopolies which are recognised by law. Legal protection granted by the Government in the form of trade mark, copy rights, license etc., give monopoly power to j the firms. Here the potential competitors are j not allowed to copy the product registered under the given brand names, patents or trade marks according to the law.

(3) Joint Monopoly or Voluntary Monopoly : This monopoly arises through mutual agreement and business combinations like the formation of cartels, syndicate, trust etc. For e.g. Oil producing nations have come together and formed a Cartel OPEC Organisation of Petroleum Exporting Countries.

(4) Simple Monopoly : A simple monopoly firm charges a uniform price for its product to all the buyers.

(5) Discriminating Monopoly : A discriminating monopoly firm charges different prices for the same product to ) different buyers. E.g. a doctor, a teacher, a lawyer, etc., charges different fees from the people. The practice of charging different j prices from different buyers is called “Price discrimination.”

(6) Private Monopoly : When an individual or a private firm enjoys the monopoly of manufacturing and supplying a particular product, it is called private monopoly. The main aim of private monopolist is profit maximisation.

(7) Public Monopoly : When a field of production is solely owned, controlled and operated by the government, it is regarded as public monopoly. Eg. Public utility service like Railways, Electricity, Water Supply etc. Since these monopolies are service motivated and welfare oriented they are also called welfare monopolies.

Answer:
In the diagram, equilibrium price is ₹ 30/- because at this point dd curve insects SS curve at point ‘P’. At this point DD is 300 doz of bananas and sellers are ready to sell 300 doz at price ₹ 3.

7. Answer in detail:

Question 1.
Explain the meaning of Monopolistic competition with its features.
Answer:

(1) Fairly large number of Sellers : There are large number of sellers selling closely related, but not identical products. There is tough competition among sellers. An individual seller supply is just a small part) of the total supply, so he has limited degree l of control over market supply and price. Each firm (seller) can formulate its own price and output policy independently.

(2) Fairly large number of Buyers: There are large numbers of buyers in a monopolistic competition market. Each buyer enjoys his preference over a particular brand and chooses to buy a specific brand of product. Hence, the buying is by choice and not by chance.

(3) Product Differentiation : The most distinguishing feature of monopolistic competition is that the product produced by different firms are not identical, they are slightly different from each other but they are close substitutes. The product differentiation can be done in different ways like may be in the form of brand names say Raymonds. It can be differentiated in terms of colour, size, design, etc., say soap, mobiles etc., or through sales technique. For e.g. cars, two wheelers, air conditioners, etc.

(4) Free Entry of Firms: A firm is free to enter the market as there are no entry barriers. Similarly there are no restrictions if the firm wants to quit the market. Freedom of entry leads to occurrence of only normal profit in the long run.

(5) Selling Cost : One of the special features of monopolistic competition is the selling cost. Selling costs are those costs, which are incurred by firms to create more and more demand for its products through advertisement, salesmanship, free samples, exhibitions, etc.

(6) Downward Sloping Elastic Demand Curve : The demand curve faced by each firm is downward sloping and comparatively more elastic. It implies that an individual firm can sell more only by reducing the price.

(7) Concept of Group : Under monopolistic competition, Prof. E. H. Chamberlin introduced the concept of group in place of Marshallian concept of industry. Industry means a number of firms producing identical products. A group means a number of firms producing differentiated product, which are close substitutes.

Question 2.
Explain the meaning of Perfect competition with its features.
Answer:

(1) Perfect Mobility of Factors of Production : Factors of production that is land, labour, capital are perfectly free to move from one firm to another or from one industry to another from one region to another or from one occupation to another. This ensures freedom of entry and exit for individuals and firms.

(2) Single / Uniform Price : There exists a single price for homogeneous product in the entire market at a given point of time. The price is determined by forces of demand and supply.

(3) Large Numbers of ellers : There are many sellers in this market. The number of sellers (firms) are so large that a single seller cannot influence the market price nor the total output in the market (Industry). The contribution of one seller is insignificant and microscopic. The price in the market is determined by the forces of market demand and market supply. Hence, a firm or seller is a ‘price taker’ and not a ‘price maker.’


(4) Homogeneous Product : The products produced by all the firms in the industry are identical and are perfect substitute to each other. The products are identical in shape, size, colour, etc. and hence uniform price rules the market for the product.

(5) Large Number of Buyers : There are large number of buyers in the market. One individual buyer’s demand is only a small fraction of total market demand so he is not in a position to influence the price. He is a price taker.

(6) No Government Intervention : It is assumed that the government does not interfere with the working of market economy. There are no tariffs, subsidies, licensing policy or other government interventions. This non – intervention of government is necessary to permit free entry of firms and automatic adjustment of demand and supply. In short, laissez faire policy prevails under perfect

(7) Perfect Knowledge : There is perfect knowledge on the part of buyers and sellers regarding the market conditions especially regarding market price. As a result no buyer will pay a higher price than the market price and no seller will charge a lower price than the market price. So a single price would prevail for a commodity in the entire market.

(8) Free Entry and Free Exit : There is freedom for new firms or sellers to enter the industry or market. There are no legal, j economic or any other type of restrictions or; barriers for new firms to enter the industry or an existing firms to quit the industry, Entry of new firm usually takes place j when existing firms enjoy abnormal profit. Similarly, existing firms quit the industry when they face losses.

(9) No Transport Cost: It is assumed that all firms are close to the market and hence there  is no transport cost. If the transport cost are added to the price of product then the homogeneous commodity will have different prices depending upon the distance from the place of supply to the market.

Question 1.
Do you know? (Textbook Page 50)
What is monopsony?
Answer:
Monopsony is opposite of monopoly market but it is rarely found in reality.
In monopsony, there are large number of sellers but buyer is only one. So buyer has complete control over the price in the market. He can bargain with the sellers and fix the price at his terms.

Question 1.
Stock and Supply.
Answer:

Stock	Supply
(a) Stock refers to the total quantity of commodity available with producer for sale.	(a)Supply is that part of stock which the seller is willing to offer for sale at a given price.
(b) It is outcome of production. If production increases, stock will also increase.	(b) It is outcome of stock. Stock is the basis of supply.
(c) It is a fund or reservoir and a static concept (inelastic).	(c) It is a flow concept. It changes according to change in price (elastic).
(d) It can exceed supply.	(d) It cannot exceed stock.

Question 2.
Expansion of Supply and Increase in Supply.
Answer:
Expansion / Extension of Supply

1. When the supply of a commodity rises only due to the rise in the price of the commodity, then it is said to be extension in supply.
2. Extension of supply is a case of variation in supply.
3. Rise in price is the only factor due to which supply expands / extends.
4. When there is extension in supply, there is an upward movement on the same supply curve.
   

Increase in Supply :

Question 4.
Average Revenue and Average Cost.
Answer:

Average Revenue (AR)	Average Cost (AC)
(a) Average revenue refers to average income earned per unit of a sold commodity.	(a)Average cost refers per unit of cost of production of a commodity produced.
(b) It is calculated by dividing total revenue (TR) earned by number of unit sold.	(b) It is calculated by dividing total cost (TC)by number of units of that commodity produced.
(c) Symbolically it in expressed as \( [latex]\frac { Total Revenue }{ Total Quantity sold }\) [/latex]	(c) Symbolically it is expressed as \(\frac { Total Cost }{ Total Quantity produced }\)
E.g. If TR from sale of 10 units of a commodity is Rs. 1000 then, AP =  1000/10 = Rs. 100	E.g. If TC of 100 units a commodity is Rs. 1000 then, AC =  \(\frac { 1000 }{ 100 }\) = Rs. 10

Answer:

Question 3.
State the relationship between price and quantity supplied.
Answer:
This diagram shows the direct relationship / between price and quantity supplied of) chocolates. When its price is ? 10, 200 units ( are supplied and as price rises to 15, 20, 25 ? …. and so on, quantity supplied also rises to )
When the schedule is plotted on the graph we 250, 300, 350 and so on. This is the law of supply of an individual firm.

B) Observe the market supply schedule of potatoes and answer the following questions.

Question 1.
Complete the quantity of potato supplied by the firms to the market in the above table.
Answer:

Question 2.
Draw the market supply curve from the schedule and explain it.
Answer:

When the schedule is plotted on the graph we get a market supply curve ‘SS’ which is upward sloping. This curve shows that as price rises from ₹ 1 to ₹ 2, supply rises from 1oo to 112 kg, but when price rises from ₹ 2 to ₹ 3, supply rises to a greater extent from 112 kg to 155 kg in the market. When price rises to ₹ 4 Supply falls from 155 kg to 154 kg. This may be because of perishable or seasonal good that supply could not Jj be increased and supply falls. This show backward bending supply curve, showing partly an exception to the supply curve.

6. Answer the following questions:

Question 1.
Explain the concept of total cost and total revenue.
Answer:
Total Cost (TC): It is the total expenditure incurred by a fir m on the factors of production required for the production of goods and services. Total cost is the sum of Total Fixed Cost (TFC) and Total Variable Cost (TVC). Total Fixed Cost is the cost incurred on fixed factors of production like land, factory, building, capital, etc. These factors cannot be changed in the short period. They remain constant. Total Variable Cost is the cost incurred on variable factors such as raw – materials, labour, etc. These factors can be varied or changed according to the change in output level. So the variable cost varies. Total Cost = Total Fixed Cost + Total Variable Cost
i.e., TC = TFC + TVC
TC increases as the level of output increases.

Total Revenue :
(Income) refers to total receipts of the firm from its sales of commodity. It is obtained by multiplying the price per unit of the  commodity with the total number of units!; of commodity sold to the consumers. Thus, Total Revenue = Price per unit Total  Number of units of commodity sold.
Example : If the firm sells lo units of a commodity at ₹ 100 per unit then total revenuewifibe TR = 100 x 10. TR= ₹ 1000

Question 2.
Explain determinants of supply.
Answer:

1. Cost of Production : Changes in the price of factors of production like rent, wages, interest affects the cost of production. When cost of production increases, supply decreases.
2. Price of Other Goods : The supply of a given commodity depends on the price of other commodity. E.g. if the price of wheat rises and that of rice remains the constant, then the producer will think of producing J more of wheat. This will affect the supply of rice.
3. price of the Commodity : Price is an important factor influencing the supply. More is supplied at a higher price and less at a lower price. So price and supply are 5 directly related.
4. Climatic Conditions : The supply of j commodity is also influenced by the forces
5. Government Policy : Government policies like taxation, subsidies, industrial policies etc., may encourage or discourage production and supply. A tax on the commodity will raise the cost of production and reduce the supply while a subsidy on the other hand will provide an incentive to increase production and supply.
6. Exports and Imports : When the
   government resort to imports, supply expands, at the same time heavy exports would reduce the supply in the domestic market.
7. Nature of Market : In a competitive market, the supply would be more but in a monopoly market the seller may create artificial scarcity to raise the price.
8. Future Expectation : If future trends indicate a rise in price, the supply decreases at present. On the other hand if the sellers expect the future price to fall, supply would increase in the current period.
9. Technique of Production : Improvement in the technique of production will lead to increase in supply. Application of advanced technology enables the producer to produce goods on large scale at a lower cost and lesser price.
10. Infrastructure Facility : If means of transport and communication are well developed, the extent of market would be wide. i.e. supply will increase.
11. Natural and Man-made Calamities : Natural calamities like earthquake, cyclone, flood etc., will affect the supply in the market. Even man-made calamities like a bomb-blast, affects supply. Even a strike call can affect supply in the market.

7. Answer in detail :

Question 1.
State and explain law of supply with exceptions.
Answer:
Law of Supply :
(A) Introduction : The law of supply was introduced by Dr. Alfred Marshall in his book “Principles of Economics” published in 1890. The law establishes a functional relationship between the price of a commodity and quantity supplied of that commodity. It explains the general tendency of the sellers in offering more goods for sale at a higher price than at a lower price.

(B) Statement of the Law : According to Prof. Alfred Marshall “Other things remaining constant, the higher the price of the commodity, greater is the quantity supplied and lower the price of the commodity, smaller is the quantity supplied.”In other words, quantity supplied of a commodity varies directly with price i.e., with a fall in price supply contract and with a rise in price supply expands.
S = f (P) [S = Supply, P = Price, f = Function of]
The law can be better understood with the help of a market supply schedule and market supply curve.

(C) Market Supply Schedule : Market supply schedule is a tabular representation of various quantities of a commodity offered for sale by all the sellers in the market at different prices during a given period of time. The schedule is a hypothetical one except one price rest are imaginary prices.

The above schedule clearly shows that sellers in general want to sell more at high prices and less at low price. E.g., at a low price of Rs.10 per unit the seller supplies only 100 units per day and at high price of Rs. 50 the supply rises to 500 units of ‘X’ per day.

(D) Market Supply Curve : It is graphical representation of the above market supply schedule. Price is measured on ‘Y’ axis and quantity supplied on ‘X’ axis and above schedule is plotted. We derive a supply curve SS.

Market Supply Schedule

Price of ‘X’ per unit (in ?)	Total Market Supply per day (in units)
10	100
20	200
30	300
40	400
50	500

There are some exceptions to the law of s supply. Following are such cases when supply may fall with the rises in price or rise with the fall in price.

(1) Labour supply : Supply of labour in the ) terms of hours of work is an important exception pointed out by economists. Generally when wages rise, workers work more, but after a certain point if wages continue to rise, supply of labour falls i.e. workers wish to earn more by work in for less hours and supply curve of labour would bend backwards as shown below :

In this figure as wage rate rises up to 0W, ;i supply of labor also rises up to ON, but when wage rate rises to 0W., labour supply falls from ON to 0Nr Hence an exception.

(2) Saving : In case of savings generally it is observed that as the rate of interest rises, savings also rises but some people want to have a fixed regular income by way of interest. They may save less at a higher rate of interest and save more at a lower rate of interest. For example : suppose a person is interested in earning a fixed income of ₹ 800 p.a. then he saves ₹ 10,000/- at 8% rate of interest but when rate of interest increases to 10%, he will save only ₹ 8,000/-.

(3) Future Expectations: If the seller expects a fall in price in future, then he will supply more today even at a low price. But if he expects the prices to rise further in future he will withhold the supply today to supply more in future at a high price.

(4) Need for Cash : When the sellers are in urgent need of liquid cash, then even at a lower price they will offer more goods for sale.

(5) Rare Goods : In case of rare collections such as rare painting, old coins, antique, the law is not applicable as the supply remains fixed. The supply curve is a vertical straight line parallel to Y axis.

(6) Agricultural Goods: Supply of agricultural product is influenced by natural factors like climatic conditions, rainfall etc., which cannot be controlled by man. So in bad weather condition, even at a higher price the supply of agricultural commodities will not increase.

Question 1.
“Concept of supply is a micro concept but concept of aggregate supply is a macro concept”. Explain. (Textbook Page No. 43)
Answer:
Micro economics studies about economic behavior of units like households, firm market and particular commodities. Whereas macro economics deals with the broad economic concepts like total demand, total supply, national income, etc.
Supply refers to supply of an individual seller and aggregate supply refers to total supply of a commodity.
Hence, supply is a microscopic concept and aggregate supply is macro concept.

If a firm produces 600 units of a commodity in a day and incurs a total cost of ₹ 30,000. Calculate the Average Cost.
Answer:
Average cost refers to the cost of production per unit cost of a commodity. It is calculated by dividing total cost by total quantity of a commodity. Hence,
AC = \(\frac{\mathrm{TC}}{\mathrm{TQ}}=\frac{30,000}{600}\) = ₹ 50 per unit

If a firm sells 400 units of a commodity at ₹ 10 unit. Calculate the TR and AR.
Answer:
TR = Price X Quantity
= 10 x 400
= 4,000
AR = \(\frac{\mathrm{TR}}{\mathrm{TQ}}\)
= \(\frac{4,000}{400}\)
= ₹ 10

Question (i)
‘Forgiveness is often better than punishment’. Write two paragraphs – one for and another against this notion.
Answer:
1. To err is human, to forgive is divine.

We all make mistakes. Nobody is perfect. That is why we are human. However, mistakes should be forgiven if there is sufficient repentance. Forgiveness will make the guilty person feel ashamed of his conduct and he will not repeat it. It is easy to punish but very difficult to forgive someone. It needs a big heart and a lot of kindness. If we punish the guilty person we will only make him more defiant. If punishing someone could have solved the problem, criminals who have been jailed would never have repeated the crime. But this is not found to be so. Just as God forgives us our mistakes, we should forgive others their mistakes too.

2. Punishment is the only answer

Forgiveness may work in certain cases, but there are hardened criminals who will not respond to forgiveness. They will only be stopped by punishment. If a person has murdered another in cold blood, will he improve by forgiveness? Never. He has to be punished severely so that he does not repeat it and society feels safe.

People only fear punishment. It can be easily seen at traffic signals – if there is no policeman to punish you, most people will break the signal. Then there will be chaos. If there is no punishment and no prisons, people will do whatever they want – rob, kill, etc. – and go off freely. No, in a society where it is not possible to expect everyone to have high values, punishment for misdeeds is the only solution.

Question (ii)

The umbrella man did not call a policeman. Give reasons for this.
Answer:
The umbrella man had himself probably stolen the umbrella from somewhere. When Soapy picked up the umbrella, the man first thought that he could get it back. But when Soapy spoke about calling a policeman, the man thought that the umbrella was actually Soapy’s, and Soapy would hand him over to the police. Hence, he apologized quickly and walked away without calling a policeman.

Personal Response:

Question 1.
Give your opinion about Soapy’s desire to enter prison.
Answer:
I find it very strange that a person can actually want to enter prison, whatever be the reason. At least, from what I know of prisons, they are terrible places, and one has a very difficult time there. However, Soapy has obviously been to prison before, and probably enjoys the free food and protection from the winter that he gets there.

Question 2.
Have you ever bought/eaten something and then found that you did not have enough money to pay for it? Describe your feeling at that time.
Answer:
Yes, it happened to me once. I went to a mall and bought a jacket for myself. I had been looking at a lot of jackets and I got confused with the prices. Finally, when the cashier was making the bill, I found that the jacket I had chosen was very expensive and I did not have enough money to pay for it. I was very embarrassed to tell the cashier this, but I had to. He gave me an angry look.

Question 3.
Have you ever stolen/wanted to steal anything? Narrate in brief.
Answer:
Yes, when I was about 12 years old, I stole my friend’s remote-controlled toy car, which his uncle had sent him from abroad. It was a beautiful car. However, when I was playing with it at home my mother saw me, and she made me return the car. I later felt very ashamed of myself, but fortunately my friend forgave me.

4. Such demand is found in case of life saving drugs, salt, etc.
5. 

6. Answer the following questions:

Question 1.
Explain the factors influencing elasticity of demand.
Answer:
The concept of Price Elasticity was developed i by great neo-classical economist Dr. Alfred \ Marshall in the year 1890.
According to Dr. Alfred Marshall, “The elasticity or responsiveness of demand in a market is great or small, according to the amount demanded which increases much or little for a given fall in price, and diminishes much or little for a given rise in price. ”
Elasticity of demand in fact refers to the £ degree of responsiveness of the quantity demanded of a commodity to change in the variable on which demand depends.

Question 2.
Explain the total outlay method of measuring elasticity of demand?
Answer:
Total Outlay Method : This method was introduced by Dr. Alfred Marshall. The limitation of this method is that in this method unlike ratio method, the exact numerical value of the elasticity of demand cannot be determined. According, to this method, the elasticity of demand is measured on the basis of expenditure incurred by consumer when the price of a commodity changes.

Total outlay or total expenditure can be calculated by multiplying the price with the quantity demanded (Price x Quantity demand = Total Expenditure). Depending upon the kind of change in total outlay, whether it increases, or decreases, or remain constant with the change in price we will be able to decide the type of elasticity. This can be explained with the following example:-

1. If the total outlay remains the same with a rise or fall in price then the demand is said to be unitary (e = 1) elastic.
2. If the total outlay decreases with a rise in price and increases with a fall in price, the elasticity of demand is greater than one or Relatively Elastic e > 1.
3. If the total outlay increases with a rise in price and decreases with a fall in price, then elasticity is less than one or relatively inelastic, e < 1.

Question 3.
Explain importance of elasticity of demand.
Answer:

• Nature of Commodity : By nature, commodities are classified as necessaries, comforts and luxuries. Normally demand for j necessaries like food grains are relatively inelastic and for comforts and luxuries like diamond, perfumes, etc is relatively elastic.
• Availability of Substitutes : The larger the number of substitutes available for a commodity, the greater would be the elasticity. Demand for products like soap, soft drinks, detergents, tooth paste, etc. have many substitute so demand is elastic, ‘j However, salt, garlic, onions have no substitute so demand is inelastic.
• Durability of the Commodity : The demand for durable goods like T.V., car, fridge, etc is relatively inelastic in the short run and elastic in the long run. Whereas the demand for perishable goods is relatively inelastic.
• Uses of Commodity : Single use commodities have less elastic demand and multi-use goods like coal, electricity, sugar, etc. have relatively elastic demand.
• Range of Price : The demand for commodities which are highly priced and will have a inelastic demand like AC, car, etc. Even very low priced goods have inelastic demand.
• Consumer’s Income : Generally if income is very high, the demand for over allcommodities tends to be relatively inelastic. The demand pattern of the rich people is rarely affected even when there is significant price change.
• Influence of Habits and Customs : When a person is habituated to consume a certain commodity, the demand will be inelastic for that commodity. E.g. demand for cigarettes to a chain smoker is inelastic.
• Time Period : The demand for goods is less elastic in the short period and more elastic in the long period. This is because (1) in the long period consumer are better informed about their price (2) habits of consumer’s change in the long run (3) durable goods get worn out in the long period.
• Proportion of Income Spend : If consumer spends a very small proportion of his income on a commodity, the demand for it will be relatively inelastic & vice-versa. For e.g. demand for salt, newspaper, pins are inelastic.
• Urgency and Postponement : If the demand for a commodity is urgent then demand for it will be inelastic. E.g. demand for medicine for a patient. Whereas, if the demand for a commodity can be postponed it will have elastic demand.
• Complementary Goods : Complementary goods are those goods which are demanded jointly such as car and petrol, mobile and sim cards, etc. Demand for petrol will be inelastic as car cannot run without petrol.

7. Observe the following figure and answer the questions:

Question 1.
Identify and define the degrees of elasticity of demand from the following demand curves.

Answer:

Concept: Perfectly Inelastic demand (Ed = 0) Explanation : When change in price has no effect on the quantity demanded of that commodity, then it is called as perfectly inelastic demand. Demand curve ‘DD’ is a vertical straight line parallel to ‘Y’ – axis.

Concept: Perfectly Elastic demand (Ed = ∞) (infinity)
Explanation: When a change in price leads to infinite change in quantity demanded of a commodity then it is called as perfectly) (d) elastic demand.
Demand curve is horizontal straight line ( parallel to ‘X’ – axis.

Concept: Ed = 1 Unitary elastic demand Explanation : When proportionate or percentage change in quantity demanded is exactly equal to proportionate or percentage change in price, then it is called as Unitary Elastic demand. Demand curve is called as rectangular hyperbola.

Concept: Relatively Elastic Demand (Ed > 1)
Explanation : When proportionate or percentage change in quantity demanded is more than proportionate change it its price, then it is called as Relatively Elastic Demand. Demand curve is called as flatter curve.

4. State with reasons whether you agree or disagree with the following statements:

Question 1.
Demand curve slopes downward from left to right.
Answer:
Yes, I agree with this statement.

Reasons justifying downwards sloping demand curve are as follows:

• The law of DiminishingMarginal Utility: Marginal utility goes on diminishing when there is increase in the stock of commodity and consumer tends to buy more when price falls and vice-versa.
• Income Effects : Whenever there is a fall in price of a commodity, purchasing power of a consumer gets increased, which enables him to buy more of that commodity.
• Substitution Effect : When price of commodity rises consumer tends to buy more of cheaper substitute goods and less of the commodity whose price has increased.
• Multi-purpose Uses : When a commodity can be used for satisfying multiple needs, its demand will rise with a fall in its price and vice-versa.
• New Consumers : When there is fall in price of a commodity, a new consumer class buy the commodity as they can afford it. Thus total demand for commodity increases with fall in price.

Question 2.
Price is the only determinant of demand.
OR
Price is the only factor that affects demand for a commodity
Answer:
No, I do not agree with the given statement. This is because there are various factors that determine demand other than price.

Reason:
The following are a few determinants:
Income of the consumer – Change in the income of the consumer also affects the market demand for goods. The effect of the change in income on the market demand depends on the type of the good.

Type of Good – The market demand for normal goods shares a positive relationship with the consumer’s income. The market demand for inferior goods (such as coarse cereals) has a negative relationship with the consumer’s income.

The market demand for Giffen goods also has a negative relationship with the income.
Consumer’s tastes and preferences – Consumers’ tastes and preferences highly influence the demand for goods. Other things being constant, if all consumers prefer a commodity over another, then the market demand for that commodity increases and vice versa.

Population size – The market demand for a commodity is also affected by the population size. Other things being equal, an increase in the population size increases the market demand for a commodity and vice-versa. This is because with the change in population size, the number of consumers in the market changes.

Question 3.
When price of Giffen goods fall, the demand for it increases.
Answer:
I Disagree with the statement.
Reason:
When price of Giffen goods falls, the demand for its decreases.
Inferior goods or low-quality goods are those goods whose demand does not rise even if their price falls. At times, demand decreases when the price of such commodities fall. Sir Robert Giffen observed this behaviour in England in relation to bread declined, people did not buy more because of an increase in their real income or purchasing power. They preferred to buy superior-good like meat. This is known as Giffen’s paradox.

6. Answer in detail :

Question 1.
State and explain the law of demand with exceptions.
Answer:
(A) Introduction : The law of demand is one of the important law of consumption which explain the functional relationship between price and quantity demanded of a commodity. Prof. Alfred Marshall in his book ‘Principle of Economics’ which was published in 1890, has explained the consumer’s behaviour as follows:

(B) Statement of the Law : According to Prof. Alfred Marshall, “Other things being equal, higher the price of a commodity, smaller is the quantity demanded and lower the price of a commodity, larger is the quantity demanded.
In other words, other things remaining constant, demand varies inversely with price. Marshall’s law of demand describes the functional relationship between demand and price. It can be presented as:
D_x = f(P_x)
where D = Demand for Commodity
x = Commodity
f = function
P_x = Price of a commodity
(C) Assumption :

• Prices of Substitute goods remain constant : The price of substitute goods should remain unchanged, as change in the price will affect the demand for the commodity.
• Prices of Complementary goods s remains constant : A change in the price j of one good will affect the demand for other,  thus the prices of complementary goods  should remain unchanged.
• No Expectation about future changes jj in prices: The consumers do not expect any \ significance rise or fall in the future prices.
• No change in Taxation Policy : The level of direct and indirect tax imposed by the government on the income and goods should remain constant.
• Constant Level of Income : Consumer’s income must remain unchanged because if income increases, consumer may buy more even at a higher price not following the law of demand.
• No Change in Tastes, Habits, Preference, Fashions, etc. : If the taste changes then the consumers preference will also change which will affect the demand. When commodities are out of fashion, then demand will be low even at a lower price.

(D) Explanation of the law of Demand :
The law of demand is explained with the help of the following demand schedule and diagram:
Demand Schedule

Price of Commodity ‘X’ (in Rs.)	Quantity Demanded of Commodity ‘X’ (in kgs)
50	1
40	2
30	3
20	4
10	5

From the above demand schedule we observe that at higher price of ₹ 50 per kg, quantity demanded is 1 kg. When price fall from ₹ 50 to ₹ 40, quantity demanded rises from 1 kg to 2 kg. Similarly, at price ₹ 30 quantity demanded is 3kg and when price falls from ₹ 20 to ₹ 10 quantity demanded rises from 4 kg to 5 kg. This shows an inverse relationship between price and demand.

In the above diagram X-axis represent quantity demanded and Y-axis represent the price of the commodity. The demand curve DD slopes downwards from left to right ] showing an inverse relationship between price and demand. It has a negative slope.

(E) Exceptions to the Law of Demand :
No, I do not agree with this statement.
There are some important cases in which the demand for the commodity is greater when price rises and smaller when price falls. Such cases are called exceptions to the law of Demand. In such case, demand curve slopes upwards from left to right and it has a positive slope.

• Prestige Goods : Rich people buy more expensive goods like gold, diamonds, etc., even when there prices are high to maintain their status.
• Giffen Paradox : Demand for low quality goods and inferior goods decrease even if there prices falls.
  According to Sir Robert Giffen when price of bread declined, people did not buy more because of increase in their real income and they prefer to buy superior goods like meat.
• Speculation : People are tend to buy more commodities if they expect prices to rise further. E.g. prices of oil, sugar, etc., are expected to rise before Diwali, so people buy more of these commodities even at higher price.
• Habitual goods : Due to habit of
  consumption, certain goods like tea is purchased in required quantities even at higher price.
•  Ignorance : Sometimes people completely ignore the price of commodity and buy more of that commodity ignoring higher price.
• Price Illusion: Consumer feels that good at higher price are of better quality, therefore demand for such goods are higher even at rise in their prices.

Question 2.
Explain in detail the determinants of demand.
Answer:
Meaning of Demand : Demand refers to a desire or want for goods. Desire is the willingness to have some commodity which is backed by willingness and ability to pay.
Definition : According to Benham, “The demand for anything at a given price is the amount of it, which will be bought per unit of time at that price.

Features of Demand :

1. Demand is a relative concept.
2. Demand is essentially expressed with reference to time and price. ?

Determinants of Demand :

1. Price of Complementary Goods : Demand changes with changes in price of complementary goods like car and petrol, etc.
2. Advertisement : Effective advertisement and sales promotion will lead to greater demand of product. E.g. cosmetics, toothbrush, etc.
3. Price : Demand for a commodity is mainly influenced by its price. Normally at a higher price the demand is less and at a lower price it is more. Thus, demand varies inversely with price of a commodity.
4. Taste, Habits and Fashions : Habits influence market demand. If people habituated to the consumption of certain goods they will not give up such habits easily. E.g. demand for liquor, cigarettes, etc. Sometimes fashion change attitude and preference of people which in turn changes market demand.
5. Income: Income determines the purchasing power. Rise in income will lead to a rise in demand of a commodity and fall in income will lead to a fall in demand of a commodity.
6. Other Factors : (a) Climatic condition, (b) Changes in technology, (c) Government policy, (d) Customs and traditions, etc.
7. Nature of Product: Under necessary and unavailable circumstances the demand of a commodity will continue to be same irrespective of the corresponding price. E.g. medicine to control blood-pressure.
8. Level of Taxation : There would be increase in price of goods and services due to high rates of taxes which results in a decrease in demand and vice-versa.
9. Expectation about the Future Prices : If the consumer expect a rise in price in the near future they will demand more at present price. Similarly, when they expect price to fall, then they will buy less at present prices.
10. Price of Substitute Goods : Demand for cheaper substitute goods will rise when there is fall in price of such goods. E.g. when sugar price rises, then the demand for jaggery will rise.
11. Size of Population: Demand for commodity depends upon size and composition of population like age structure, gender ratio which influence demand for certain goods. E.g. larger the child population, more will be the demand for toys, chocolates, etc.

3. Write short notes on.

Question 1.
Factors affecting regional development.
Answer:
The physical factors like relief, climate, location, population and land use of the region affects the regional development.

Regional development occurs near areas with favourable location, plain relief, sufficient rainfall, developed agriculture, transportation, industries and trade. For example, Asian countries have developed agriculture and trade of agricultural goods. USA has developed industries and trade.

There is poor development of economic activities in areas with unfavourable relief like mountains or hills and extreme climate. For example, in the northern part of Russia, economic development is poor due to extreme cold climate.

Location of the region is an important factor. If there is a long and broken coastline, then there is development of ports and thus development of trade and economy. For example, Japan has economically developed in spite of limited natural resources, due to development of trade.

On the other hand, landlocked countries remain isolated. They cannot develop trade due to absence of coastline. Such countries have poor economic development. For example, Afghanistan, Nepal.

The economic development in any region depends upon the quantity and quality of its people.

Where more suitable land is available, different economic activities are developed. For example, cities use land for various purposes such as industries, education, entertainment, transport, commerce, etc. Therefore, cities have economic development.

Hence, physical factors are said to affect the economic development of the region.

Question 2.
Measures to reduce regional imbalance.
Answer:

• The following measures along with numerous policies are considered by the government to reduce regional imbalance.
• The underdeveloped regions are identified and its economic, physical and social reasons for the non-development are studied.
• Regions which require monetary support in a particular sector or field are funded through sector-wise investments to improve the conditions.
• Subsidies are given to certain sectors. Investment is made for improvements of roads, schools, agriculture, irrigation, industries, housing, medical and health facilities, etc.
• Special attention is given to areas facing problems such as frequent droughts, deserts or hilly and tribal-dominated areas.
• The very important strategy to reduce regional imbalances is decentralisation of industries.

4. Give geographical reasons.

Question 1.
Regional development is dependent on physical setting.
Answer:

• The physical factors like relief, climate and location of the region affect the regional development.
• Regional development occurs where agriculture, agro-based industries and trade is developed in areas where there is plain relief and sufficient rainfall. For example, Asian countries have developed agriculture and trade of agricultural goods.
• Plain relief and sufficient rainfall encourage development of transportation and industries.
• There is poor development of economic activities in areas with unfavourable relief like mountains or hills and extreme climate. For example, in the northern part of Russia, economic development is poor due to extreme cold climate.
• Location of the country is an important factor. If there is a long and broken coastline, then there is development of trade and economy. For example, Japan has economically developed in spite of limited natural resources, due to the development of trade.
• On the other hand, landlocked countries remain isolated. They cannot develop trade due to absence of coastline. Such countries have poor economic development. For example, Afghanistan, Nepal.
• Thus, there is relationship between regional development and physical factors and therefore, we can say the regional development depends on physical factors.

Question 2.
Factors like literacy, poverty affect the regional development.
Answer:

• Literacy and poverty are the important factors affecting the regional development.
• High literacy rate determines the quality of human population. This increases the availability of employment opportunities and development of resources, which contributes to the economic growth and regional development.
• Due to high literacy rate, the population growth is controlled and resources are shared among less people in the country.
• However, poverty decreases the purchasing powers resulting in a decline in the demand for goods, which reduces the production and drops the economic development and GDP of a country.
• Hence, poverty and literacy affect regional development.

Question 3.
Development is not seen in the Himalayan region.
Answer:

• Relief and climate are the most important factors affecting the development of any region.
• The Himalayan region has high mountains with a steep slope. The climate is cold and the mountains are covered with snow. There is heavy soil erosion and hardly plain land, so agriculture is not developed.
• In this mountainous region, it is difficult and expensive to develop transportation facilities. Hence, there is poor development of industries.
• Since all above factors are neither suitable for agricultural, industrial or trade development is not seen in the Himalayan region.

5. Answer the following questions in detail.

Question 1.
What is a region?
Answer:

• A region is an area of a country or any part of the world having common features. Thus, there is a difference between two regions on the basis of its features.
• The common features may be physical (relief, climate, soil, natural vegetation, etc.), socio¬cultural factors (language, religion, etc.), man-made like political features (administrative or political boundaries).
• Regions may be small or large. The large regions include sub-regions. For example, the plateau region of India has various sub-regions such as Chota Nagpur plateau, Malwa plateau, Marwar plateau, Deccan plateau, etc.

The main characteristics of regions are :

• Regions have its geographical location mentioned in latitudes and longitude.
• Every region has a specific boundary, the area of another region starts beyond that boundary.
• The extent of a region depends upon the homogeneity of a region.
• There are sub-regions in one region and therefore regions can be arranged into different orders on the basis of same features.

There are two types of regions – formal and functional regions.
1. A formal region is also known as uniform region or homogeneous region. It is an area in which everyone shares in common one or more distinctive characteristics. It can be common physical characteristic such as relief or climate of the region. It can be socio-cultural or economic activity such as common language. For example, rice producing regions.

2. In some formal regions, there are boundaries. Thus, district, state or country may be formal region. For example, USA and Canada are the examples of formal regions.

3. In functional regions characteristics are not important but functions are more important.

4. In one functional region, there may be many political or physical regions but due to one common function it is said to be functional. For example, Mumbai metropolitan or Pune metropolitan regions.

5. Functional regions act as a focal point that connects surrounding areas by transportation and communication. For example, Mumbai metropolitan city is well connected with its surrounding areas through transportation.

Question 2.
On what factors are the regions differentiated? Give examples.
Answer:
A region is an area of a country or any part of the world with same common features. Thus, regions are differentiated on the basis of physical or man-made or socio-cultural factors.

For example, Chota Nagpur plateau region has plateau relief. Himalayan mountain region has mountainous relief. The desert region of Rajasthan has shortage of rainfall and very high temperature. Northern plain region has plain relief, fertile soil and moderate climate.

The region may be differentiated on the basis of man-made factors like political factors such as administrative boundaries or political boundaries. For example, Uttar Pradesh and Punjab are two different regions because they have different political boundaries and government bodies.

The region may be differentiated on the basis of socio-cultural factors such as language, religion or ethnicity. For example, in Mumbai there is an area, where people speaking Gujarati language live in one region. The Middle East countries form one region where people of Muslim religion stay together.

Thus, regions are differentiated on the basis of various factors.

Question 3.
Per capita income is not the real indicator of regional development. Explain.
Answer:

• The per capita income is the income of per person in the country or region. It is the ratio between the country’s national income and total population.
• Per capital income is an index of development because more the per capita income, higher the standard of living of people. But it is not always true.
• The per capita income gives an idea about the average income of people in the country but it does not explain how income is distributed among the people. Some people may be rich and some may be below the poverty line.
• The per capita income is related to only economic aspect of the country but it does not take into account literacy rate, health, sex ratio, age structure, life expectancy etc.
• Sometimes rise in per capita income is due to increase in prices of commodities.
• If the population is low the per capita income will be high, but the regional development will be slow, because such regions have shortage of skilled labour supply for further development. Therefore, we can say that the per capita income is not the real indication of regional development.

6. Find the correlation between land under permanent crops and GDP given in the table 7.5 using Spearman’s Rank Correlation. Write the conclusion in your own words.

Answer:

X₁ = Land under permanent crops
Y₁ = GDP
R₁ = Rank – 1, R₂ = Rank – 2, n = 12 (No. of pairs)
Rank correlation R = 1 – \(\frac {6Σ(R_1-R_2)^2}{n(n^2-1)}\)
= 1 – \(\frac {6×118}{12(144-1)}\)
= 1 – \(\frac {708}{1716}\)
= 1 – 0.412
= 0.588
= 0.59

The answer of correction between (1) Land under permanent crops (2) GDP is 0.59 or +0.59 which means there is a positive correlation between these two variables.

It is not perfect positive correlation (+1.0). It is slightly less than this i.e. (+0.59).

It means when the amount of land under permanent crops is more, GDP is also more and when the amount of land under permanent crops is less, GDP is also less.

This is because the production of crops contributes to the growth of GDP.

The answer 0.59 suggests that this is not true for all countries as there are other factors, activities, products which are responsible for the growth of GDP other than the production of crops.

(iv) The country (region) K has more land use under forest.
(iv) The region G has the highest land use under category ‘other land’. Its GDP is 1391.5 billion dollars.
(v) The region I is having highest GDP in which there is 50% arable land, it means agriculture must be major activity.

The region A is having lowest GDP where land under permanent meadows and pastures is highest. It means there is limited development of agricultural activities.

It is surprising, region F where arable land is highest in percentage even then GDP is comparatively low, because the land under permanent crop is very less.

In region K, GDP is 5747.49 and land under forest is 66%. It must be because the development of lumbering activities and forest-based industries is greater.

The region G has the highest area under other land use (95.6%) and GDP 1391.25. This region must have developed activities other than agriculture and forestry.

(v) In which region would you like to stay? Why?
Answer:
(i) I think in region A more resources are available.
(ii) I think in region A people are richer.
(iii) People may be happier in region A because of higher per capita income, less population below poverty line, more urbanisation, more net sown area under irrigation.
(iv) I do not think the given indicator or factors are enough to decide the standard of living because other important factors like literacy rate, enrolment ratio / dropout ratio, sex ratio, crime rate etc., are not taken into consideration
(v) I will like to stay in region A because in this region per capita income is high, population below poverty line is low, percentage of urbanisation is highest, net sown and irrigated area is highest.

Question 2.
(i) Looking at the five stages of demographic transition theory, countries in which stage do you think, will be called developed?
(ii) Having looked at the various shapes of pyramids, which pyramid will represent a developed country? (Fig 2.1, Textbook Page No. 12)
(iii) After having answered both the questions above, what can you comment upon the role of population in regional development? (Textbook Page No. 70)
Answer:
(i) Countries in stage 4 and 5 will be called developed for e.g., USA, Sweden, Finland.
(ii) The pyramid (C) will represent a developed country.
(iii) The role of population in the regional development of any country is very important as man is a human resource. Quality of human resources is very important, which depends upon birth rate, death rate, expectancy of life, literacy ratio, male female ratio, mortality rate, etc.

A country having to qualitatively better population will help in the regional development of that country. For example, qualitatively population of the USA is better than population of India and hence, in USA there is better regional development than India.

Think about it

Question 1.
(i) Does development mean maximum utilisation of resources?
(ii) Does development consider environment as an indicator?
(iii) Can a region be called developed if it has sparse population or no population? (Textbook Page No. 69)
Answer:
(i) Development does not mean maximum utilisation of resources. Development of a region is the function of its resources and its population. There are many factors which affect the development of a region. For the holistic development of regions, skilled human resources and optimum utilisation of natural resources is necessary.

(ii) We must consider the environment as an indicator of development. Development at the cost of the environment is not real development. Since we ignore the environment while developing economy in the past 50 years, we are now suffering by many environment problems like global warming, etc.

(iii) Population is one of the most important factors in development. If there is sparse population or no population, then there will be shortage of man-power and resources will remain unutilized and therefore, quantity and quality of human resources is very important in the process of development.

Give it try

Question 1.
Draw a conclusion on the basis of the data given in table 7.4. Use Spearman’s Rank Correlation, find the correlation between the two variables. What can you comment about the development in this region? (Textbook Page No. 71)

Answer:

X₁ Percentage of malnourished children about to enter school.
Y₁ Government expenditure on education (% of total budget)
R₁ = Rank – 1, R₂ = Rank – 2, n = 8
Rank correlation R = 1 – \(\frac {6Σ(R_1-R_2)^2}{n(n^2-1)}\)
= 1 – \(\frac {6×104}{8(64-1)}\)
= 1 – \(\frac {624}{8(63)}\)
= 1 – \(\frac {624}{504}\)
= 1 – 1.24
= -0.24

The correlation between the percentage of malnourished children about to enter school and government expenditure on education is -0.24.
This value is very near to zero, which means no correlation. Hence, it is very slightly a negative correlation.

It means where the percentage of malnourished children about to enter school is more, the government expenditure on education is less e.g., in E region percentage of children is 31.7% but the expenditure is 4.09% and in C region percentage of children is only 3.4% but the expenditure is 7.10% (highest).

Considering the fact, we cannot consider this as well developed. There is no logical sequence in distribution of government expenditure on education. It is necessary that government authorities should take into consideration actual status of the region, need of the region before releasing grant to that region. This will surely help in proper allocation of the funds and overall development of the region.

Question 2.
Go through the fig. 7.2 and write two sentences on each factor. Tell how they will help in reducing regional imbalance. Also add some more to the list, if necessary. (Textbook Page No. 73)
Answer:
No country, in the world is having uniform regional development and thus, there is regional imbalance in development. Hence, a country must have a regional imbalance reduction strategy. Regional imbalance can be reverted through provision of public/services to backward areas by providing drinking water, education facilities and electricity to all.

It can also be reverted by making provision of infrastructure stimulus by allotment of special funds, development of special skills, good governance, support to infrastructural project and policy review and reform.

Question 1.
Look at the following data and answer the questions that follow: (Textbook Page No. 72)

(i) In which region is contribution of primary activities the least?
(ii) In which region is the contribution of primary activities the most?
(iii) In which region the contribution of tertiary activities is the most?
(iv) Which region has the highest HDI?
(v) Can you draw a conclusion on basis of the answers from Q (i) to Q (iv)?
Answer:
(i) In region A, the contribution of primary activities is the least.
(ii) In region E, the contribution of primary activities is the most.
(iii) In region B, the contribution of tertiary activities is the most.
(iv) In region A, there is highest HDI.
(v) We can conclude by saying that Human Development Index is high in countries where contribution of secondary and tertiary sector to GDP is high compared to the contribution of primary sector to GDP.

Region A, B, C and D have more than 30% contribution of secondary sector to GDP and more than 60% contribution of tertiary sector to GDP, it means these regions are developed regions.

The contribution of primary sector to GDP in region E is more but the contribution from secondary and tertiary sector is less compared to other regions, so region E is in the developing stage.

Utility of sweater increases in winter season.

Question 2.
Nilesh purchased ornaments for his sister.
Answer:
Concept: Possession utility.
Explanation : When the ownership of a product changes from seller to buyer, it is called possession utility.
In the given example, ornaments are purchased by Nilesh for his sister. Ownership of a product changed, so it is an example of possession utility.

Question 3.
Kavita consumed five units of oranges one after the other.
Answer:
Concept: Successive consumption.
Explanation : To experience the law of DMU, there should be consumption of units of commodity, without time gap. It is called successive consumption.
The given example explains that five oranges are consumed by Kavita one after another without interval of time.

Question 4.
Bhushan refused to eat fifth chapati after eating four chapatis.
Answer:
Concept: Disutility.
Explanation : When the want is fully satisfied, a consumer realises full satisfaction i.e. point of satiety.
But, beyond this point, he experiences negative utility. So, he refuses to consume any more unit of commodity.
If consumption continues, it results into disutility.

5. Answer in detail:

Question 1.
State and explain the law of diminishing margmal utility with exceptions.
OR
State and explain the law of DMU? Explain its assumptions.
Answer:
Law of Diminishing Marginal Utility :
(A) Introduction:
The law of diminishing M.U. explains economic behaviour of a rational consumer.
The law was first proposed by Prof. Gossen and further explained in detail by Prof. Alfred Marshall in his book “Principles of J economics” published in 1890.
The law of DMU is universal in nature. It ) indicates common consumer’s behaviour that Marginal Utility diminishes with reduction in the intensity of want.

(B) Statement of the Law :
According to Prof. Alfred Marshall, “Other things remaining constant, the additional benefit which a person derives from a given increase in his stock of a thing, diminishes with every increase in the stock that he already has”.
In simple words, law of DMU can be stated as follows :
“Other things being the same, MU goes on ) diminishing with every successive unit of a j commodity consumed.”

Thus, the law of DMU explains that, the more of a thing you have, the less you want to have more of it.
In short, as consumption of identical units of commodity increases, MU diminishes.

(C) Assumptions of the law of DMU :
Assumptions are those conditions which are necessary for the validity of the law. They are as follows :

• Cardinal Measurement: The law assumes that utility can be measured cardinally i.e. in numbers. So, it is possible to express and compare the utility derived from each unit of commodity consumed.
• Homogeneity : It is assumed that all the units of commodity consumed are homogeneous or same. They are identical in case of size, shape, taste, colour, flavor, etc.
• Rationality : A consumer is assumed to be rational. His behaviour is normal from economic’s point of view. It means, he tries to get maximum satisfaction.
• Continuity : All units of commodity are consumed successively, one after another, without time interval.
• Reasonability : The law assumes that, all the units of commodity consumed are reasonable in size. The unit of measurement is neither too big nor too small e.g. a cup of tea, glass of water, etc.
• Divisibility : A commodity is assumed to be divisible. So it is possible to divide the units of commodity in a proper size.
• Constancy : It is assumed that related factors like income, taste and preference, habits, choice of a consumer remain constant. MU of money is also assumed to be constant.
• Single want: A given commodity is used to satisfy a single want of a person. So that it is possible to experience full satisfaction from a single want.
• Schedule and Diagram :
  The law can be explained with the help of following schedule and diagram :

Units of Commodity	Marginal Utility (M.U)
1	10
2	8
3	6
4	4
5	2
6	0
7	-2

The above given schedule shows that MU goes on diminishing with an increases in units of commodity consumed.
Graphical Presentation :

In the above given diagram, X-axis indicates units of commodity and Y-axis measures marginal utility.
Various points are plotted on the graph which indicates MU derived from each unit } of commodity consumed.
When all these point are joined, we get MU curve. It slopes downward from left to right. It shows that MU diminishes as consumption of a commodity increases.
The shaded portion of the diagram shows negative utility. It is because, beyond a certain level, further consumption of a commodity results into disutility.

(E) Exceptions to the law of Diminishing M.U.
Exceptions are those cases for which the law is not applicable. They are as follows :

1. Hobbies
2. Miser
3. Addictions
4. Power
5. Money
6. Reading

They are explained as under :
(1) Hobbies : The law of DMU is not applicable in case of collection of stamps, coins, rare paintings, etc. It is because, when its stock increases, M.U. may increases because it gives more and more satisfaction.
However, it violates the assumptions like homogeneity and continuity.

(2) Miser : For a miser, every additional rupee gives him more and more pleasure.
So, when the stock of money increases, MU of money tends to rise.
However, the behavior of a miser is irrational. It violates the assumption of rationality.

(3) Addictions : It is said that, the level of intoxication increases for drunkard with every additional consumption of liquor. It may increase MU for him.
This condition is similar to most of the addictions.
Here again, the assumptions like rationality and continuity are violated.

(4) Power: It is an exception to the law of DMU because, when a person acquires power, his craze for power increases MU from power. As a person gets power, he desires to have more and more of it.
But, it violates the rationality, assumption.

(5) Money : Money is used as a medium of exchange. It helps to buy goods to satisfy human want. So MU of money increases with an increase in its stock.
MU of money never becomes zero. The law holds true to money too. MU of money declines slowly as its stock increases. So MU of money is more for poor than rich people.

(6) Reading : When a person reads more and more, he gets deeper and deeper knowledge so MU of reading tends to increase. Similarly the law does not hold true in case of music, dance, etc.
However, assumptions like continuity, homogeneity, etc. are violated.
The law of DMU is universal in nature. These cases are not real exceptions as they violate some assumptions.
So, it is said that, there are no real exceptions to the law of DMU.

Write an informative note on the paradox of values along with examples.
Answer:
The paradox of values –
The concept of value paradox is introduced by Adam Smith.
The term value has two meanings
(i) Value in use
(ii) Value in exchange
Some goods have greater value in use but the smaller value in exchange e.g. water.
However, some goods have smaller value in use but a greater value in exchange e.g. diamond.
So, the paradox of value is also called a water-diamond dilemma.
Greater value in use denotes high total utility whereas, greater value in exchange shows high marginal utility.
Thus, the concept paradox of value is very useful to understand the concepts of utility i.e., Total Utility & Marginal Utility.

Good manners are required in our daily life for making our social contacts more cooperative and friendly. Illustrate the behaviour of the polite conductor with different people in various situations.

Answer:

Situation	Behaviour
1. The writer’s sensitive toe was trampled on	The conductor said sorry with an apology and courtesy.
2. In the rainy season dealing with people	He would run up the stairs to give someone the tip that there was “room inside”.
3. Dealing with old people	He was as considerate as a son.
4. Dealing with children	He was as solicitous as a father.
5. Dealing with young people	He always indulged in some merry jest with them.
6. Dealing with a blind man	He set him down safely on the pavement and then took him wherever he wanted to go, after telling the driver to wait for a while.

Question (v)
Discuss and Write the impact of good temper and kindliness on society in the light of the good-mannered conductor.
Answer:
The conductor was always cheerful and kind-hearted to everyone in the bus. This spread to his passengers and they too became cheerful and good-humored. They would naturally pass on this feeling after getting off the bus. Thus, in society, if people are good-tempered, cheerful and kind, it will spread to others and they too will start behaving in a similar manner. This will lead to a happy and compassionate society.

Question (vi)
‘A modest calling can be made dignified by good temper and kindly feeling’. Explain the statement with examples.
Answer:
This means that whatever career or job one has, however simple or modest, it can be made more dignified by behaving in a good- tempered and cheerful manner and with kindliness towards the people one comes in contact with. For example, even a simple job like that of a security guard at a mall can be made pleasant and dignified if the guard smiles and says ‘Thank you’ or ‘Good morning’ every time he/she checks a person.

A sweeper’s job can also be made more dignified if he/she just nods and smiles at passers-by or helps them if they are in need.

Question (vii)
The service of the police is necessary for the implementation of law in our society. Do you think you require this service for a good social environment? Discuss and write.
Answer:
No, we cannot have the police monitoring us for social and moral offences. For example, one cannot be punished if one refuses to smile at an acquaintance or say Thank you’. One cannot be punished if one doesn’t hold the door open for the person who is following.

These are good manners, or courtesy, and they have to be taught right from childhood, and they will change in different cultures and different circumstances. Whether a person follows them or not depends on the individual. However, if these little courtesies are followed, life will become much simpler and more pleasant for everyone.

Question (i)
Write a speech on ‘Courtesy is the light of life’ with the help of the following points.
(a) People have a good impression of you.
(b) You will be acknowledged and appreciated by all.
(c) You will he happier and contented with life.
Answer:
Courtesy is the light of life
Dear friends,

Good morning. You may be surprised with the topic I have chosen for this speech, for today the word ‘Courtesy’ seems to be an old-fashioned word for us. But it is really the light of life. I, Shivam Goswami, would like to say a few words on why I think so.

First of all, what does courtesy mean? It means good manners and polite behaviour. It means being kind and compassionate towards someone. When you are courteous, people have a good impression of you; but that is not the reason for being courteous. Politeness should be real, and not artificial.

A courteous person will be appreciated by all. People will like to spend time with him/her and find pleasure in the person’s company. Someone may ask ‘What is courteous behaviour’? Saying simple words like ‘Please’, ‘Thank you’, ‘Excuse me’ and ‘Sorry’ is courteous behaviour. Helping a person who has fallen is courteous behaviour. Holding the lift door open for someone is courteous behaviour.

When a person is courteous, people are automatically courteous in return. This leads to a more polite and happier society. As I conclude, I would like to ask all of you to do something for a week: Be courteous. Then you will see the returns and realize the truth of what I am saying. Thank you for listening to me so patiently. Bye.

Question (ii)
‘Manners maketh man’ – Expand the idea in your own words with proper examples.
Answer:
Manners maketh man

‘Manners maketh Man’ : so goes a famous saying. In the world of today, people are judged by their manners and conduct. Manners distinguish us from animals, and make us human. A person who is courteous and considerate towards others is said to possess good manners. Such a person is respectful to his superiors, courteous to his equals and sympathetic towards his subordinates. He always shows concern for the well-being and comfort of others. He uses words like ‘Please’, ‘Thank you’ and ‘Sorry’ while talking to others; he helps senior citizens and those in need.

Everyone likes a person who speaks and behaves politely and treats others respectfully. Good manners cost practically nothing but can buy everything. They win us friends and help us influence people. They make the world a happier place to live in by reducing friction and avoiding tension.

When we meet a person for the first time, it is the person’s courtesy which impresses us deeply. Good manners are generally taught by parents at home, and by teachers in school. Manners that are learnt during childhood generally remain with us throughout our lives. They become a part of our personality. Hence, it is desirable that good manners are instilled in children when they are very young, so that they grow up to become courteous, considerate adults.

The area of moral offences is quite vast and no laws or commandments can cover this area.

Hence, it is not possible for the law to become the guardian of our private manners.

In the opinion of the writer, the liftman, instead of throwing the passenger out of the lift, should have treated him with elaborate politeness.

Inference/Interpretation/Analysis :

Question 1.
Name the ‘unpleasant specimen’ mentioned in the extract and describe his behaviour.
Answer:
The ‘unpleasant specimen’ mentioned in the extract is the type of bus conductor who regards his passengers as natural enemies whose chief purpose on the bus is to cheat him, and who can only be kept honest by using a loud voice and an aggressive manner.

Question 2.
Describe the stale old trick, according to the conductor.
Answer:
Pretending that you have forgotten your purse at home, and hence do not have the fare for the ticket is a stale old trick, according to the conductor. (The conductor does not say this the narrator only imagines that he may do so.)

Question 3.
Describe the reactions of the bus conductor.
Answer:
No, the conductor did not think that the narrator was dishonest. He cheerfully accepted what the narrator said without doubting him and offered him a free ticket.

Question 4.
Describe the experience which made the narrator comfortable in the bus.
Answer:
The conductor had trampled on the narrator’s sensitive toe, causing him pain and agony. However, the conductor had then explained matters and apologized so profusely that the narrator forgot his pain and anger. After this experience, the narrator always observed his constant good nature and cheerful behaviour with pleasure and felt comfortable in his presence.

Question 5.
Describe the narrator’s justification of his praise of the conductor.
Answer:
The narrator says that if the famous poet Wordsworth could gain wisdom from a poor leech-gatherer, he sees no reason why ordinary people should not take lessons on conduct from a bus conductor, who shows how a modest job can be made more dignified by behaving in a good-tempered and cheerful manner and with kindliness towards the people one comes in contact with.

Personal Response:

Question 1.
Describe a person you have come across who is always polite and helpful. What do you think about him/her?
Answer:
The security guard of our building is always polite and helpful. He will help senior citizens get in and out of their cars or into the lift; he will help any person who has heavy bags. He also replies politely to any question asked by anyone. We all like him very much and often share our chocolates and biscuits with him. We also give him books, stationery and toys for his little child.

Question 2.
Describe a pleasant/unpleasant experience you have had with a bus conductor.
Answer:
This is an experience I had when I was new to Mumbai. I got into a bus and asked the conductor for a ticket to Dadar. The conductor shook his head and told me that I had got into the bus going in the wrong direction. He patiently explained that I would have to get off at the next stop, cross the road, and catch a bus having the same number but going in the opposite direction. He even pointed out the bus stop to me. Though I felt a bit embarrassed, I thanked him for his kindness.

Question 3.
Give your opinion about the conductor’s behaviour.
Answer:
The conductor was really a good and kind human being who saw the best in everyone and believed everyone. He was ready to pay the fare for the narrator’s ticket himself, even though he was not sure whether it would be returned. It is difficult to find such generous and helpful people in the world today, and it leaves a very pleasant feeling in the heart when you do.
