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

Question 1.
Partition values have application only in theory but not in practice.
OR
Partition values are not useful in economics.
Answer:
No, I do not agree with the statement.

  • Partition values like quartiles are useful to economists to know the final information related to income, sales, stock data, etc.
  • Also, deciles and percentiles help economists to measure in the detail the poverty line, inequality of income, household, wealth, etc.
  • Hence, partition values are useful in Economics.

Question 2.
Average can misinterpret the representative value.
Answer:
Yes, I agree with the statement.

  • Average is not based on all observations because it is a positional average and their values are affected by sampling fluctuations.
  • Averages give more importance to larger values and less to smaller values.
  • Thus, such data can misinterpret the representative value.

Maharashtra Board Class 11 Economics Solutions Chapter 3 Partition Values

Question 3.
Median is also known as the second quartile.
Answer:
Yes, I agree with the statement.

  • Median is the middlemost value in the arranged data.
  • It is the value that divides the series into two equal parts, so that the number of items above it, is equal to the number of items below it.
  • It is not affected by extreme values.
  • Median = n/2 and Q2 = 2 (n/4) i.e n/2.
  • Therefore, the Median is equal to the second quartile.

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

Question 1.
There are no difficulties in the barter system.
Answer:
No, I do not agree with the statement.
A barter system is a process of exchange under which people exchange goods and services produced by them with goods and services produced by others. With the progress of civilization, human wants to be multiplied and the barter system of exchange became obsolete. This was because of various inherent limitations. They are as follows:

  • Lack of double coincidence of wants: Barter exchange cannot take place unless there is a double coincidence of wants. Under Barter System wants may not always coincide.
  • Lack of common measure of value: In the Barter System, there was no common measuring unit of account, so it was difficult to calculate the value of goods to be exchanged.
  • The problem of storage: There was the problem of storage under Barter exchange because most of the commodities exchanged were agricultural in nature. Such as rice, wheat, etc. which were perishable.
  • The problem of divisibility: There was the problem of divisibility when it was a bulky commodity. E.g. exchange of rice and wheat with the horse was difficult.
  • The problem of making deferred payments: Future payment was not possible in the Barter exchange. Borrowing and lending were difficult.

Question 2.
There are many good qualities found in modern currency.
Answer:
Yes, I agree with the statement.
There are many good qualities found in a modern currency like:

  • General Acceptability: It must be generally accepted as a medium of exchange.
  • Stability: The purchasing power of money should be stable because money serves as a store of value.
  • Cognizability: It must be easily recognizable or identifiable. For E.g. Notes of different denominations must be of different sizes, colours, etc. so that they can be easily identified.
  • Durability: Money should be durable also i.e. its value should not fluctuate too much.
  • Divisibility: Money should be divisible into units of smaller denominations.
  • Portability: It should be easy to handle and carry from one place to another.
  • Homogeneity: Money of the same denomination should be identical in shape, size, colour, etc.

Maharashtra Board Class 11 Economics Solutions Chapter 2 Money

Question 3.
Many tasks are accomplished with money.
Answer:
Yes, I do agree with the statement.
Money performs a number of functions in today’s economy. They are as follows:

  • Medium of Exchange: It serves as a medium of exchange, i.e. any commodity can be purchased or sold for money.
  • The measure of Value: Money helps to compare the price of commodities in the modern economy, which was not possible during the Barter period. Value of commodity can be expressed in different currencies like Rupee in India, Dollar in the U.S.A., etc.
  • Standard of deferred payment: Deferred payment means making payment at a future date. This was not possible in a barter economy, because taking loans was easy, but its repayment was difficult as the loan was in form of grains, cattle, etc.
  • Store of value: Money made possible the habit of saving for the future. Saving was not possible during the barter economy as commodities started deteriorating after a certain period of time. But with the invention of money, now it can be saved for a longer period.
  • Transfer of value: Transfer of money from one person to another and from one place to another place, became possible due to the invention of money.
  • Contingent Functions: Besides the above functions of money, there are other functions of money, like
    • it helps to measure National Income.
    • it forms the basis of credit.
    • it imparts liquidity to wealth.
    • it helps to estimate macroeconomic variables.

Question 4.
Money can be sent anywhere through electronic means.
Answer:
Yes, I do agree with the statement.

  • With the invention of new technologies, like mobile phones, tablets, smart cards, computers, etc, money can be sent anywhere nationally or globally.
  • E-money is a monetary value that is stored and transferred as and when desired through various means.
  • It is the safest mode of transfer as it is backed and monitored by the Central Bank.
  • It is also called a digital wallet.
  • Hence, money can be sent anywhere through electronic means.
