5. Think and answer in your own words.

Question (a)
What common characteristics did Marie and Pierre share, as a student?
Answer:
When Marie went to Sorbonne the University of Paris she spent her days in poverty. Her friend Pierre was brilliant but a poor scientist. Due to lack of money they began to work in a shabby laboratory. Being students they were brilliant scholars but poverty was an obstacle in their way.

Question (b)
Which of the two scientists was greater than the other? Say why.
Answer:
I think Madame Curie was greater than Pierre Curie because she wanted to study in Paris but the poverty at home did not allow her to continue. But with her own efforts and confidence she could fulfil her childhood dream. Even in that condition she got married to a person who was poor. And even after his death, she did not deter and continued her work and was awarded the Nobel Prize. It shows that she was really a great human being and a scientist.

Question (c)
Why was the gift of a ton of pitchblende, a great stroke of luck to the Curies?
Answer:
Being very expensive the Curies couldn’t buy pitchblende on a large scale but when their admirer, the emperor of Austria gifted them the most precious gift of a ton of pitchblende they could do their experiment on a large scale and find out what they wanted to achieve. So it was a great stroke of luck to the Curies.

Question (d)
Besides the uses of Radium and Polonium mentioned in the text, in what other way do you think, it is used in the field of medicine?
Answer:
Radium is used to produce radon gas which in turn, is used to treat cancer. Radiation given off by radium is sometimes used also to study the composition of metals, plastics and other material.

The alpha rays emitted by Polonium can be used to eliminate static electricity. Polonium is also used in anti-static brushes to eliminate dust on photographic film.

Question (e)
What proves that Marie Curie was a true lover of humanity and not of wealth?
Answer:
Marie Curie could have patented her discovery and earned a lot of money. But she believed in working for Science and whatever she discovered belonged to the people and not to her so in real sense she thought about humanity not money. She was a true lover of humanity and not of wealth.

To,
The Headmaster,
New English High School,
Akola.
Subject: Requirement of scientific equipment, apparatus and formulae charts for the laboratory.

Respected sir,

With regard to learning Science content, processes and views of the nature of Science experiments play significant role in Science. As per the new syllabus, new subjects and some experiments are included in revised Science coursebooks. Experiments give immense pleasure of self-learning and observations.

The equipment and apparatus that we have been using in our Science laboratory are outdated and rarely of any use. If we bring some new, definitely it will arose interest in learning Science and doing some experiments on our own. Being in-charge of Science Committee, I request you on behalf of all students and teachers to bring following equipment and apparatus in our Science laboratory.

1. 2 compound microscope
2. 2 Hand lens
3. 6 Beakers
4. 3 Beakers Tongs
5. 3 Test Tube holder
6. Thermometer
7. Safety goggles-6
8. 6 funnels
9. 1 microwave oven
10. 2 pipette
11. Graduated Cylinder
12. Vernier Calliper
13. Meters
14. Compass
15. Stop clock

You are well aware that due to lack of equipment our Science teachers can’t conduct some experiments in the lab.

Hope you will understand our difficulty and buy the listed equipment and apparatus as early as possible so that the subject of Science can be well understood by doing various experiments in the laboratory.
Anticipating your valuable help in this respect.

Thanking you,

Yours obediently,
Sanjay Sharma
In-charge of Science Committee.

10. ‘There is no short-cut to success’. Expand this maxim with a suitable introduction, body, examples and conclusion. Write it in your notebook in about 20 lines.

Question 1.
‘There is no short-cut to success’. Expand this maxim with a suitable introduction, body, examples and conclusion. Write it in your notebook in about 20 lines.
Answer:
‘There is no Short-cut to Success.’
It is often said that success requires hardwork and great diligence as well as commitment. This makes success a long-term achievement. Everybody thinks that there are some easier ways to live life, no need to work hard for livelihood but the truth is that easier ways are always the toughest ways. Most of us forget that for reaching success, the road is not strewn with roses. Success is an achievement by constant diligence and most of us lack the essential quality, diligence. The magic of hardwork and perseverance cannot be underestimated.

Most of the time it happens that we start our efforts but soon lose heart half-way and give up our efforts and thus fail to reach the pinnacle of success. If we have the confidence in our efforts, there is nothing that can deter us from achieving. Sitting in front of Television and watching the shopping network channel, fascinating over the new-miracle making abs machine which promises you the six- pack abs only in 5 minutes of daily exercises, you think that product is heaven sent, so you grab your phone book the order and start dreaming about your perfect body. Two months later, that wonder abs machine is at the back of your master closet gathering dust. As you can see, you will have to do the work when reaching a goal and the success that comes with it.

You have to understand that you might have to make sacrifices during your journey and you need to put in the hours required in order to get where you want to reach. Those who sit pretty and just complain about the success of others are the ones who do not do much in life. Those who make continuous efforts for a long time in the right direction rarely lose in the struggle of life. So one important password for all of us to follow is that there is no short cut to success.

Question 5.
What proves Marie’s strong will power?
Answer:
When the couple could not buy pitchblende which was an expensive substance they sacrificed all the luxuries of life to save money. They lived in extreme poverty. They could not buy costly food and warm clothes for extremely cold Parisian winter. They could not sleep due to lack of warmth. Marie refused to take rest whenever her husband begged her to give up the struggle. All the above incidents prove that Marie had a strong will power to achieve the aim of her life.

Question 6.
Why were the two new substances named Polonium and Radium?
Answer:
When Pierre and Marie found two new substances in their new discovery, she called one Polonium in honour of her country Poland and being the most powerful of the radioactive elements another was called “Radium”.

Question 7.
Which gift did she receive from the emperor of Austria? Why was it the most precious for them?
Answer:
Pitchblende is a very expensive substance which Pierre and Marie could not afford to buy in large quantity for their experiments. The emperor of Austria was an admirer of the Curies. So he gifted them a ton of pitchblende so that the Curies could carry out their experiments easily.

Question 8.
How is radium used in the medical field?
Answer:
The benefits of radium in the world of medicine are incalculable. It has been used with great effect in treatment of cancer. The bacteria of such diseases as typhus, cholera and anthrax can also be killed by radium so it was a great gift in the medical field.

Question 9.
How did Pierre meet with an early death?
Answer:
In 1906 Pierre was knocked down and killed by a horse – drawn wagon and thus met with an early death leaving Marie disconsolate.

Question 10.
What makes Marie Curie an exceptional scientist?
Answer:
When Marie and Perrie discovered Radium and Polonium they could have patented their discovery and become rich but Marie refused to do so and gave it free to the world and the world of medicine. She also believed that Radium belongs to the people not to her. She worked selflessly without expecting money. Her humanity and selflessness make Marie Curie an exceptional scientist.

Question 11.
Describe how Curies first sighted Radium. What was its colour?
Answer:
After continuing their work for more than four years on a September night, the Curies after a day’s tiresome work, went to the laboratory to have another look at the hundreds of small bowls into which they had poured filtered pitchblende. While moving forward in the dark laboratory they found rays of soft, bluish purple light coming from the small glass-covered bowls. Thus they sighted the Radium for the first time. Its colour was bluish purple.

Question 1.
Imagine that you are the captain of your school Kabaddi/Football team. Your final match is against a very strong team. Prepare a short pep-talk of about 60 to 80 words that you would give as a Captain, to encourage your team.
Answer:
My dear teammates,

I have heard about a good quotation-winning or losing a game is not important but playing with spirit is important. We get good and useful experiences as participants. Success is not always about winning but being happy with the participation and playing to fullest ability.

We know that strength of our team is each individual member and the strength of each member is the team. The player that fights and works the hardest will always come out on the top. If you find out the strength in you and push forward to work hard for yourself and for the team, I am sure you can do a lot.

Leave your negativity and get in the habit of the doing things the right way in the game. Blaming others for not reaching your goal is pointless. It is your goal and you are the only one who can achieve it. I know champions are those who work to the point of exhaustion when no one else is watching.

Use your calibre and be a champion and success will be yours.
All the best!

Answer:
Wishing Good morning to Captain Squire, Joan said that he was to give her a horse and armour and some soldiers, and send her to the Dauphin. Robert felt that, that girl was indeed mad so he asked Steward why he had not told him about it. Hearing this Steward told him not to anger her and requested him to give her what she wanted.

After hearing his remark Robert got furious and told Joan that he would send her back to her father with orders to put her under lock and key. But Joan was confident and told him that he thought he would. But it wouldn’t happen that way. She further said that he said he would not see her but there she was. Robert asked her if she was assuming that he would give her what she wanted.

Joan confidently said that he would do so and continued that a horse would cost sixteen francs. It was a big amount of money. But she could save it on the armour. She didn’t need beautiful armour made to her measure, she could find a soldier’s armour that would fit her well enough. She wouldn’t want many soldiers and the Dauphin would give her all, she needed, to free Orleans. After hearing her Robert was shocked and asked if she could free Orleans. She continued with confidence and told him that, it was true and only three men would be enough for him to send with her. Polly and Jack had promised to come with her.

Answer:
(A)

Problem Set 4b Algebra Class 10 Question 2. Find the purchase price of a share of FV ₹ 100 if it is at premium of ₹ 30. The brokerage rate is 0.3%.
Solution:
Here, Face Value of share = ₹ 100,
premium = ₹ 30, brokerage = 0.3%
MV = FV + Premium
= 100 + 30
= ₹ 130
Brokerage = 0.3% of MV
= \(\frac { 0.3 }{ 100 } \) × 130 = ₹ 0.39
Purchase price of a share = MV + Brokerage
= 130 + 0.39
= ₹ 130.39
Purchase price of a share is ₹ 130.39.

Question 3.
Prashant bought 50 shares of FV ₹ 100, having MV ₹ 180. Company gave 40% dividend on the shares. Find the rate of return on investment.
Solution:
Here, Number of shares = 50, FV = ₹ 100,
MV = ₹ 180, rate of dividend = 40%
∴ Sum invested = Number of shares × MV
= 50 × 180
= ₹ 9000
Dividend per share = 40% of FV
= \(\frac { 40 }{ 100 } \) × 100
Dividend = ₹ 40
∴ Total dividend on 50 shares = 50 × 40
= ₹ 2000

∴ Rate of return on investment is 22.2%.

Question 4.
Find the amount received when 300 shares of FV ₹ 100, were sold at a discount of ₹ 30.
Solution:
Here, FV = ₹ 100, number of shares = 300,
discount = ₹ 30
MV of 1 share = FV – Discount
= 100 – 30 = ₹ 70
∴ MV of 300 shares = 300 × 70
= ₹ 21,000
∴ Amount received is ₹ 21,000.

Question 5.
Find the number of shares received when ₹ 60,000 was invested in the shares of FV ₹ 100 and MV ₹ 120.
Solution:
Here, FV = ₹ 100, MV = ₹ 120,
Sum invested = ₹ 60,000

∴ Number of shares received were 500.

Question 6.
Smt. Mita Agrawal invested ₹ 10,200 when MV of the share is ₹ 100. She sold 60 shares when the MV was ₹ 125 and sold remaining shares when the MV was ₹ 90. She paid 0.1% brokerage for each trading. Find whether she made profit or loss? and how much?
Solution:
For purchasing shares:
Here, sum invested = ₹ 10,200, MV = ₹ 100

For selling shares:
60 shares sold at MV of ₹ 125.
∴ MV of 60 shares = 125 × 60
= ₹ 7500
Brokerage = \(\frac { 0.1 }{ 100 } \) × 7500 = ₹ 7.5
∴ Sale value of 60 shares = 7500 – 7.5 = ₹ 7492.5
Now, remaining shares = 102 – 60 = 42
But 42 shares sold at MV of ₹ 90.
∴ MV of 42 shares = 42 × 90 = ₹ 3780
∴ Brokerage = \(\frac { 0.1 }{ 100 } \) × 3780 = ₹ 3.78
∴ Sale value of 42 shares = 3780 – 3.78 = ₹ 3776.22
Total sale value = 7492.5 + 3776.22 = ₹ 11268.72
Since, Purchase value < Sale value
∴ Profit is gained.
∴ Profit = Sale value – Purchase value
= 11268.72 – 10210.2
= ₹ 1058.52
∴ Smt. Mita Agrawal gained a profit of ₹ 1058.52.

Question 7. Market value of shares and dividend declared by the two companies is given below.
Face value is same and it is 7 100 for both the shares. Investment in which company is more profitable?
i. Company A – ₹ 132,12%
ii Company B – ₹ 144,16%
Solution:
For company A:
FV = ₹ 100, MV = ₹ 132,
Rate of dividend = 12%
Dividend = 12% of FV

∴ Rate of return of company B is more.
∴ Investment in company B is more profitable.

Question 8. Shri. Aditya Sanghavi invested ₹ 50,118 in shares of FV ₹ 100, when the market value is ₹ 50. Rate of brokerage is 0.2% and Rate of GST on brokerage is 18%, then How many shares were purchased for ₹ 50,118?
Solution:
Here, FV = ₹ 100, MV = ₹ 50
Purchase value of shares = ₹ 50118,
Rate of brokerage = 0.2%, Rate of GST = 18%
Brokerage = 0.2% of MV


∴ 1000 shares were purchased for ₹ 50,118.

Question 9. Shri. Batliwala sold shares of ₹ 30,350 and purchased shares of ₹ 69,650 in a day. He paid brokerage at the rate of 0.1% on sale and purchase. 18% GST was charged on brokerage. Find his total expenditure on brokerage and tax.
Solution:
Total amount = sale value + Purchase value
= 30350 + 69650
= ₹ 1,00,000
Rate of Brokerage = 0.1 %
Brokerage = 0.1 % of 1,00,000
= \(\frac { 0.1 }{ 100 } \) × 1,00,000
= ₹ 100
Rate of GST = 18%
∴ GST = 18 % of brokerage
= \(\frac { 18 }{ 100 } \) × 100
∴ GST = ₹ 18
Total expenditure on brokerage and tax
= 100 + 18 = ₹ 118
∴ Total expenditure on brokerage and tax is ₹ 118.

Alternate Method:
Brokerage = 0.1 %, GST = 18%
At the time of selling shares:
Total sale amount of shares = ₹ 30,350
Brokerage = 0.1% of 30,350

For purchasing shares:
Total purchase amount of shares = ₹ 69,650
Brokerage = 0.1% of 69,650
= \(\frac { 0.1 }{ 100 } \) × 69650
= ₹ 69.65
GST = 18% of 69.65
= \(\frac { 18 }{ 100 } \) × 69.65
= ₹ 12.537
∴ Total expenditure on brokerage and tax = Brokerage and tax on selling + Brokerage and tax on purchasing
= (30.35 + 5.463) + (69.65 + 12.537)
= ₹ 118
∴ Total expenditure on brokerage and tax is ₹ 118.

Question 10. Sint. Aruna Thakkar purchased 100 shares of FV 100 when the MV is ₹ 1200. She paid brokerage at the rate of 0.3% and 18% GST on brokerage. Find the following –
i. Net amount paid for 100 shares.
ii. Brokerage paid on sum invested.
iii. GST paid on brokerage.
iv. Total amount paid for 100 shares.
Solution:
Here, FV = ₹ 100,
Number of shares = 100, MV = ₹ 1200
Brokerage = 0.3%, GST = 18%
i. Sum invested = Number of shares × MV
= 100 × 1200 = ₹ 1,20,000
∴ Net amount paid for 100 shares is ₹ 1,20,000.

ii. Brokerage = 0.3% of sum invested
= \(\frac { 0.3 }{ 100 } \) × 1,20,000 = ₹ 360
∴ Brokerage paid on sum invested is ₹ 360.

iii. GST = 18% of brokerage
= \(\frac { 18 }{ 100 } \) × 360 = ₹ 64.80
∴ GST paid on brokerage is ₹ 64.80.

iv. Total amount paid for 100 shares
= Sum invested + Brokerage + GST
= 1,20,000 + 360 + 64.80
= ₹ 1,20,424.80
∴ Total amount paid for 100 shares is ₹ 1,20,424.80.

Question 11. Smt. Anagha Doshi purchased 22 shares of FV ₹ 100 for Market Value of ₹ 660. Find the sum invested. After taking 20% dividend, she sold all the shares when market value was ₹ 650. She paid 0.1% brokerage for each trading done. Find the percent of profit or loss in the share trading. (Write your answer to the nearest integer)
Solution:
For purchasing shares:
Here, FV = ₹ 100, MV = ₹ 660, Number of shares = 22, rate of brokerage = 0.1%
Sum invested = MV × Number of shares
= 660 × 22
= ₹ 14,520
Brokerage = 0.1 % of sum invested
= \(\frac { 0.1 }{ 100 } \) × 14520 = ₹ 14.52
∴ Amount invested for 22 shares
= Sum invested + Brokerage
= 14520 + 14.52
= ₹ 14534.52
For dividend:
Rate of dividend = 20%
∴ Dividend per share = 20 % of FV

∴ Percentage of profit in the share trading is 1 % (nearest integer).

Alternate Method:
For purchasing share:
Here, FV = ₹ 100, MV = ₹ 660, Number of shares = 22, rate of brokerage = 0.1%
Sum invested = MV × Number of shares
= 660 × 22
= ₹ 14,520
Brokerage = 0.1 % of MV
= \(\frac { 0.1 }{ 100 } \) × 660 = ₹ 0.66
Amount invested for 1 share = 660 + 0.66
= ₹ 660.66
For dividend:
Rate of dividend = 20%
Dividend = 20% of FV = \(\frac { 20 }{ 100 } \) × 100 = ₹ 20
For selling share:
MV = ₹ 650, rate of brokerage = 0.1%
Brokerage = 0.1 % of MV
= \(\frac { 0.1 }{ 100 } \) × 650 = ₹ 0.65 100
Amount received after selling 1 share
= 650 – 0.65 = 649.35
∴ Amount received including divided
= selling price of 1 share + dividend per share
= 649.35 + 20
= ₹ 669.35
Since, income > Amount invested
∴ Profit is gained.
∴ profit = 669.35 – 660.66 = ₹ 8.69
Profit Percentage = \(\frac { 8.69 }{ 660.66 } \) × 100= 1.31%
∴ Percentage of profit in the share trading is 1 % (nearest integer).

Hints:

Question 2.
Find the fourth term from the end in an
A.P.: -11, -8, -5, …, 49.
Solution:
The given A.P. is
-11,-8,-5, ……. 49
Reversing the A.P., we get 49, …, -5, -8, -11
Here, a = 49, d = -11 -(-8) = -11 + 8 = -3
Since, t_n = a + (n – 1)d
∴ t₄ = 49 + (4 – 1)(-3)
= 49 + (3) (-3)
= 49 – 9
= 40
∴ Fourth term from the end in the given A.P. is 40.
[Note: If an AY. is reversed, then the resulting sequence is also an A.P.]

Question 3.
In an A.P. the 10^th term is 46, sum of the 5^th and 7^th term is 52. Find the A.P.
Solution:
For an A.P., let a be the first term and d be the common difference.
t₁₀ = 46, t₅ + t₇ = 52 …[Given]
Since, t_n = a + (n – 1)d
∴ t₁₀ = a + (10 – 1)d
∴ 46 = a + 9d
i. e. a + 9d = 46 …(i)
Also, t₅ + t₇ = 52
∴ a + (5 – 1)d + a + (7 – 1)d = 52
∴ a + 4d + a + 6d = 52
∴ 2a + 10d = 52
∴ 2 (a + 5d) = 52
∴ a + 5d = \(\frac { 52 }{ 2 } \)
∴ a + 5d = 26 …(ii)
Subtracting equation (ii) from (i), we get

Substituting d = 5 in equation (ii), we get
a + 5(5) = 26
∴ a + 25 = 26
∴ a = 26 – 25 = 1
t₁ = a = 1
t₂ = t₁ + d = 1 + 5 = 6
t₃ = t₂ + d = 6 + 5 = 11
t₄ = t₃ + d = 11 + 5 = 16
The required A.P. is 1,6,11,16,….

Question 4.
The A.P. in which 4^th term is -15 and 9^th term is -30. Find the sum of the first 10 numbers.
Solution:
t₄ = -15, t9 = – 30 …[Given]
Since, t_n = a + (n – 1)d
∴ t₄ = a + (4 – 1)d
∴ – 15 = a + 3d
i. e. a + 3d = -15 …(i)
Also, t₉ = a + (9 – 1)d
∴ -30 = a + 8d
i.e. a + 8d = -30 …(ii)

∴ The sum of the first 10 numbers is -195.

Question 5.
Two given A.P.’s are 9, 7, 5, … and 24, 21, 18, … If nth term of both the .progressions are equal then find the value of n and n,h term.
Solution:
The first A.P. is 9, 7, 5,…
Here, a = 9, d = 7- 9 = -2
∴n^th term = a + (n – 1)d
= 9 + (n – 1) (-2)
= 9 – 2n + 2
= 11 – 2n
The second A.P. is 24, 21, 18, …
Here, a = 24, d = 21 – 24 = – 3
∴ n^th term = a + (n – 1)d
= 24 + (n – 1) (-3)
= 24 – 3n + 3
= 27 – 3n
Since, the nth terms of the two A.P.’s are equal.
∴ 11 – 2n = 27 – 3n
∴ 3n – 2n = 27 – 11
∴ n = 16
∴ t₁₆ = 9 + (16 – 1) (-2)
= 9 + 15 × (-2)
= 9 – 30
∴ t₁₆ = -21
∴ The values of n and n^th term are 16 and -21 respectively.

Question 6.
If sum of 3^rd and 8^th terms of an A.P. is 7 and sum of 7th and 14th terms is -3, then find the 10th term.
Solution:
for an A.P., let a be the first term and d be the common difference.
According to the first condition,
t₃ + tg = 7
∴ a + (3 – 1) d + a + (8 – 1)d = 7 …[∵ t_n = a + (n – 1)d]
∴ a + 2d + a + 7d = 7
∴ 2a + 9d = 7 …(i)
According to the second condition,
t₇ + t₁₄ = -3
∴ a + (7 – 1)d + a + (14 – 1 )d = -3
∴ a + 6d + a + 13d = -3
∴ 2a + 19 d = – 3 …(ii)
Subtracting equation (i) from (ii), we get

Question 7.
In an A.P. the first term is -5 and last term is 45. If sum of all numbers in the A.P. is 120, then how many terms are there? What is the common difference?
Solution:
Let the number of terms in the A.P. be n and the common difference be d.
Then, a = -5, t_n = 45, S_n = 120
Since, t_n = a + (n – 1)d
∴ 45 = -5 + (n – 1)d
∴ 45 + 5 = (n – 1)d
∴ (n – 1)d = 50 …(i)

Substituting n = 6 in equation (i), we get
(6 – 1)d = 50
∴ 5d = 50
∴ d = \(\frac { 50 }{ 5 } \) = 10
∴ There are 6 terms in the A.P. and the common difference is 10.

Alternate Method:
Let the number of terms in the A.P. be n.
Then, t₁ = a = -5, t_n = 45, S_n = 120

∴ There are 6 terms in the A.P. and the common difference is 10.

Question 8.
Sum of 1 to n natural numbers is 36, then find the value of n.
Solution:
The natural numbers from 1 to n are
1,2, 3, ……, n.
The above sequence is an A.P.
∴ a = 1, d = 2 – 1 = 1
S_n = 36 …[Given]
Now, S_n = \(\frac { n }{ 2 } \) [2a + (n – 1)d]
∴ 36 = \(\frac { n }{ 2 } \) [2(1) + (n – 1)(1)]
∴ 36 = \(\frac { n }{ 2 } \) (2 + n – 1)
∴ 36 × 2 = n (n + 1)
∴ 72 = n (n + 1)
∴ 72 = n² + n
∴ n² + n – 72 = 0
∴ n² + 9_n – 8n – 72 = 0
∴ n(n + 9) – 8 (n + 9) = 0
∴ (n + 9) (n – 8) = 0
∴ n + 9 = 0 or n – 8 = 0
∴ n = -9 or n = 8
But, n cannot be negative.
∴ n = 8
∴ The value of n is 8.

Question 9.
Divide 207 in three parts, such that all parts are in A.P. and product of two smaller parts will be 4623.
Solution:
Let the three parts of 207 that are in A.P. be
a – d, a, a + d
According to the first condition,
(a – d) + a + (a + d) = 207
∴ 3a = 207
∴ a = \(\frac { 207 }{ 3 } \)
∴ a = 69 …(i)
According to the second condition,
(a – d) × a = 4623
∴ (69 – d) × 69 = 4623 …[From (i)]
∴ 69 – d = \(\frac { 4623 }{ 69 } \)
∴ d = 69 – 67
∴ d = 2
∴ a – d = 69 – 2 = 67
a = 69
a + d = 69 + 2 = 71
∴ The three parts of 207 that are in A.P. are 67, 69 and 71.

Question 10.
There are 37 terms in an A.P., the sum of three terms placed exactly at the middle is 225 and the sum of last three terms is 429. Write the A.P.
Solution:
Since, there are 37 terms in the A.P.

Substituting d = 4 in equation (i), we get
3a + 54(4) = 225
∴ 3a + 216 = 225
∴ 3a = 225 – 216
∴ 3a = 9
∴ a = \(\frac { 9 }{ 3 } \) = 3
∴The required A. P. is
a, a + d, a + 2d, a + 3d, …., a + (n – 1)d
i.e. 3, 3 + 4,3 + 2 × 4, 3 + 3 × 4,…, 3 + (37 – 1)4
i.e. 3, 7,11,15, …,147

Question 11.
If first term of an A.P. is a, second term is b and last term is c, then show that sum of all

Solution:

Question 12.
If the sum of first p terms of an A.P. is equal to the sum of first q terms then show that the sum of its first (p + q) terms is zero, (p ≠ q)
Solution:
For an A.P., let a be the first term and d be the common difference.
The sum of first n terms of an A.P. is given by
Sn = [2a + (n – 1)d]
According to the given condition,
Sp = Sq


∴ The sum of the first (p + q) terms is zero

Question 13.
If m times the m^th term of an A.P. is equal to n times n^th term, then show that the (m + n)^th term of the A.P. is zero.
Solution:
According to the given condition,
mt_m = nt_n
∴ m[a + (m – 1)d] = n[a + (n – 1)d]
∴ ma + md(m – 1) = na + nd(n- 1)
∴ ma + m²d – md = na + n²d – nd
∴ ma + m²d – md – na – n²d + nd = 0
∴ (ma – na) + (m²d – n²d) – (md – nd) = 0
∴ a(m – n) + d(m² – n²) – d(m – n) = 0
∴ a(m – n) + d(m + n) (m – n) – d(m – n) = 0
∴ (m – n)[a + (m + n – 1) d] = 0
∴ [a+ (m + n – 1)d] = 0 …[Dividing both sides by (m – n)]
∴ t_(m+n) = 0
∴ The (m + n)^th term of the A.P. is zero.

Question 1.
Find the value.
i. | 15 – 2|
ii. | 4 – 9|
iii. | 7| x | -4|
Solution:
i. |15 – 2| = |13| = 13
ii. |4 – 9| = |-5| = 5
iii. |7| x |- 4| = 7 x 4 = 28

Question 2.
Solve.

Solution:
i. |3x – 5| = 1
∴ 3x – 5 = 1 or 3x – 5 = -1
∴ 3x = 1 + 5 or 3x = -1 + 5
∴ 3x = 6 or 3x = 4

ii. |7 – 2x| = 5
∴ 7 – 2x = 5 or 7 – 2x = -5
∴ 7 – 5 = 2x or 7 + 5 = 2x
∴ 2x = 2 or 2x = 12
∴ x = \(\frac { 2 }{ 2 }\) or x = \(\frac { 12 }{ 2 }\)
∴ x = 1 or x = 6

∴ 8 – x = 10 or 8 – x = -10 .. [Multiplying both the sides by 2]
∴ 8 – 10 = x or 8 + 10 = x
∴ x = -2 or x = 18
