Area
He bought field (A) at the rate of Rs 95 for a square metre, field (B) at Rs 110 for a square metre and field (C) at Rs 120 for a square metre. Find the cost of all three fields.
For Field (A)
Area = 756 square m, rate = Rs 95 per square m.
Total cost = 756 × 95
Therefore, the total cost is Rs 71820.
For Field (B)
Area = 432 square m, rate = Rs 110 per square m.
Total cost = 432 × 110
Therefore, the total cost is Rs 47520.
For Field (C)
Area = 513 square m, rate = Rs 120 per square m.
Total cost = 513 × 120
Therefore, the total cost is Rs 61560.
Now, the total cost of all the three fields = 47520 + 61560 + 71820 = Rs 180900

b) Each letter a, b, c stands for a number
Take a = 1, then find what the numbers b and c
Put a = 1 and complete the multiplication steps as shown below.
Now compare the result with the given question. We have b = 2, and c = 3.
To help farmers the State Government gave cows. Kamla Bai Gudhe also got a cow.
The cost of the cow was Rs 17,500. She had to pay Rs 5,500 and the government spent the rest of the money.
a) How much did the government spend on the cow?
b) If 9 people from her village got cows, how much did the government spend in all?
a) The cost of one cow is Rs 17,500, and Rs 5,500 needs to be paid by the owner. The government spends:
17,500 – 5,500 = 12,000
Therefore, the government spends Rs 12,000 on one cow.
b) Since the government spends Rs 12,000 on one cow, to find its total spending on 9 cows multiply 12,000 by 9.
12,000 × 9 = 1,08,000
Therefore, the government spent Rs 1,08,000 altogether.
But Kamla Bai was not happy, she had to spend Rs 85 every day on the cow. She made some money by selling the milk. But still she wanted to sell the cow.
a) If Kamla Bai spends Rs 85 a day, find out how much she will spend in one month.
b) The cow gives 8 litre of milk every day. How much will it give in one month?
c) If the milk is sold at Rs 9 per litre, how much money will Kamla Bai make in one month? ___________
d) So the money spent on keeping the cow was Rs ___________
e) Money earned by selling the milk Rs ___________ f) Which is more — money spent on the cow or money earned from it? How much?
g) Explain why she wanted to sell the cow.
a) Kamla Bai spends Rs 85 per day. To find her spending in one month, multiply 85 by 30.
85 × 30 = 2550
Therefore, she will spend Rs 2550 in one month.
b) The cow gives 8 L milk per day. To find the amount of milk in one month, multiply 30 by 8.
8 × 30 = 240
Therefore, the cow will give 240 L of milk in one month.
c) The milk is sold at Rs 9 per litre and the amount of milk the cow will give in one month is 240 L. Therefore, earning in one month by selling the milk is:
9 × 240 = 2,160
Therefore, she will earn Rs 2,160 in one month by selling the milk.
d) The money spent for keeping the cow is Rs 2,550 per month.
e) The money earned by selling the milk is Rs 2,160 per month.
f) The money spent on the cow is more
Money spent for the cow – Money earned by selling milk
= 2550 – 2160 = Rs 390
g) Since the money spent on keeping the cow is more than the money earned by selling the milk, she wanted to sell the cow.
a) Sukhi works on a farm. He is paid Rs 98 for one day. If he works for 52 days, how much will he earn?
Since he is paid Rs 98 for one day, multiply 52 by 98 to find his earning for 52 days.
Therefore, Sukhi will earn Rs 5096 in 52 days.
b) Hariya took a loan to build his house. He has to pay back Rs 2,750 every month for two years. How much will he pay back in 2 years?
1 year = 12 month
⇒2 years = 12 × 2 = 24 months
Since he pays Rs 2,750 per month, multiply 2,750 by 24 to find the total payback amount in 2 years.
Therefore, Hariya will pay back Rs 66,000 in 2 years.
c) Ratiram is a milk seller in the city. He sells 13 litres of milk every day at Rs 23 per litre. How much does he earn?
1 L milk is for Rs 23. To find the cost of 13 L of milk, multiply 23 by 13.
Therefore, Ratiram earns Rs 299.
e) A company sells 1 litre of packed water for Rs 12. A shopkeeper buys 240 litres of packed water. How much does he pay?
The price of 1 L of packed water is Rs 12. To find the price of 240 L water, multiply 240 by 12.
Therefore, the shopkeeper pays Rs 2,880.
c) Tricks with your age.
Write your age __________

Thulasi and her husband work on Karunya’s farm. The Government has said that farm workers should be paid at least Rs 71 for one day’s work. But he pays Rs 55 to Thulasi and Rs 58 to her husband.
a) If Thulasi works for 49 days, how much money does she get?
b) If her husband works for 42 days, how much money does he get?
c) Find the money they earn together.
a) Thulasi earns Rs 55 per day.
To find her earning for 49 days, multiply 55 by 49 as:
Therefore, she will get Rs 2695 for 49 days of work.
b) Her husband gets Rs 58 per day. To find his earning for 42 days, multiply 58 by 42 as:
Therefore, he will get Rs 2436 for 42 days.
c) Together they earn:
Rs 2695 + Rs 2436 = Rs 5131
Governments of different states have said that farm workers should not be paid less than this salary for a day’s work.
The table shows the amounts fixed by four states.
a) For farm work which state has fixed the highest amount? Which state has fixed the lowest?
b) Bhairon Singh is a worker in Rajasthan. If he works for 8 weeks on the farm, how much will he earn?
c) Neelam is a worker in Haryana. If she works for 2½ months on the farm, how much will she earn?
d) How much more will a farm worker in Madhya Pradesh get than a worker in Orissa after working for 9 weeks?
a) Observe the given table. The highest amount is fixed by Haryana, that is Rs 135 for one day’s work. The lowest amount is fixed by Rajasthan, that is Rs 73 for one day’s work.
b) 1 week = 7 days
So, 8 weeks = 8 × 7 = 56 days
In Rajasthan the payment is Rs 73 per day. To find the payment for 8 weeks (56 days), multiply 73 by 56 as:
Therefore, the correct answer is Rs 4088.
c) We know that 1 month = 30 days.
month = 15 days.
Therefore, 2½ months = (2 × 30) + 15 = 75 days.
In Haryana the payment for one day’s work is Rs 135. To find the payment for 75 days, multiply 135 by 75 as:
Therefore, the correct answer is Rs 10125.
d) 1 week = 7 days
⇒9 weeks = 9 × 7 = 63 days
In Orissa the payment for one day is Rs 75. To find the payment for 63 days, multiply 75 by 63.
75 × 63 = 4725
In Orissa the payment for one day is Rs 75. To find the payment for 63 days, multiply 75 by 63.
75 × 63 = 4725
In Madhya Pradesh the payment for one day is Rs 97. To find the payment for 63 days, multiply 97 by 63.
97 × 63 = 6111
The difference between 9 weeks earning in these two states is:
6111 – 4725 = 1386
Hence, the correct answer is Rs 1386.
Satish is a 13 year old boy. His father had taken a loan for farming. But the crops failed. Now Satish’s mother has to pay Rs 5000 every month for the loan. Satish started working — he looked after 17 goats of the village. He earns Rupee 1 every day for one goat.
a) How much will he earn in one month?
b) Does he earn enough to help pay the loan every month?
c) How much will he earn in one year?
a) Satish gets Rupee 1 per day for one goat.
For 17 goats, he will get Rs 17 per day.
To find his monthly earning, multiply 30 by 17.
30 × 17 = 510
Therefore, Satish will earn Rs 510 in one month.
b) Since the repayment of the loan amount is Rs 5000 per month but his monthly earning is only Rs 510, it is not enough help to pay the loan.
c) Satish earns Rs 510 in one month. To find his earning in one year, multiply 510 by 12.
Therefore, Satish will earn Rs 6120 in one year.
d) A farmer sells 1 litre of milk for Rs 11. In one month, he sells 210 litres of milk. How much does he earn in a month?
1 L of milk is sold for Rs 11. To find the price of 210 L of milk, multiply 210 by 11.
Therefore, the farmer earns Rs 2,310 in a month.
a) Look for the pattern and take this forward.

There are 28 laddoos in 1 kg. How many laddoos will be there in 12 kg? If 16 laddoos can be packed in 1 box, how many boxes are needed to pack all these laddoos?
In 1 kg there are 28 laddoos. To find the number of laddoos in 12 kg, multiply 28 by 12.
28 × 12 = 336
Therefore, there are 336 laddoos in 12 kg.
Since 16 laddoos can be packed in one box, to find the required number of boxes to pack 336 laddoos divide 336 by 16.
Therefore, 21 boxes are required to pack all the laddoos.
