Amount |

50-rupee | 1 | 50-rupee |

20-rupee | 1 | 20-rupee |

2-rupee | 3 | 3 × 2 = Rs 6 |

25-paisa | 3 | 3 × 25 =75 paise |

Hence, the total amount shown is: Rs 50 + Rs 20 + Rs 6 + 75 Paisa = Rs 76 and 75 paise

b. 100 paise = 1 rupee

Notes and Coins |

Hence, the correct answer is Rs 9.50.

c. From the given picture, a notebook is for Rs 5, a pencil is for
Rs. 2.50, so two pencils will cost Rs 5.

An eraser is for Rs 1, so 2 erasers will cost Rs 2 Add these
values to find the total cost.

5 + 5 + 2 = 12

Hence, the correct answer is Rs 12.

d.From the given picture, one top is for Rs 2. So, the cost of 2
tops is

out how much money will be left after buying the following
items:

a. One ball, one doll, and one toy giraffe. Total cost _______.
Money left_______

b. Two bananas, one pack of biscuits, and two glasses of lemon
juice. Total cost ________. Money left _______

c. Three notebooks, two pencils, and two erasers. Total cost
_________. Money left _________.

**Answer : **

a. Cost of one ball, one doll, and one giraffe are Rs 7, Rs 8, and
Rs 6.50 respectively.

Total cost = Rs7 + Rs 8 + Rs 6.50 = Rs 21.50.

From 30 rupees the money left is:

Rs 30 – Rs 21.50 = Rs 8.50

Hence, total cost Rs 21.50. Money left Rs 8.50.

b. Cost of Two bananas, one pack of biscuits, and two glasses of
juice are Rs 3.00, Rs 4.50, and Rs 6.00, respectively.

Total cost = Rs 3 + Rs 4.50 + Rs 6 = Rs 9 + Rs 4.50 = Rs 13.50

From 30 rupees, the money left is:

Rs 30 – Rs13.50 = Rs 16.50

Hence, total cost Rs13.50. Money left Rs16.50.

c. Cost of three notebooks, two pencils, and two erasers are Rs
15, Rs 5.00, and Rs 2, respectively.

Therefore, the total cost = Rs 15 + Rs 5 + Rs 2 = Rs 20 + Rs2 = Rs
22

From 30 rupees, the money left is:

Rs30 – Rs22 = Rs 8

Hence, total cost Rs 22. Money left Rs 8.

**Practice Time**

**Question 11 : **Three friends wanted to buy a

hundred-rupee note. How much money should she borrow from her
friends to pay the bill?

**Answer : ** She bought the things for Rs 58, Rs 37,
and Rs 22. Total amount spent is:

Rs 58 + Rs 37 + Rs 22 = Rs117

Since she had Rs 100, subtract Rs 100 from Rs 117 to find the
difference.

Rs 117 – Rs 100 = Rs 17

Hence, she should borrow Rs 17.

**Question 14 : **Mumbai News

Children Freed from Factory

10 young children working in a bangle factory were set free today.
A news reporter and the police found them in a sad condition. The
factory made the children work very hard. It paid them only Rs 80
a day. The children are happy to go back to their homes in their
village. They will go to a special school so that they can learn
to study like other children their age. By making children work,
the factory tries to save money. The police will now take action.
Let us see how much money the factory tries to save.

Money 1 older worker should get = Rs 513 a day

Money 1 child is paid = Rs 80 a day

On 1 person the factory saves Rs 513 – _____ = Rs 433 a day

On 10 persons the factory saves

Rs 433 × 10 = Rs _____ a day.

**Answer : **
To find the savings of the company on a child per day, subtract
the money a child gets for a day from the money an older person
gets for a day.

Rs 513 − Rs 80 = Rs 433

Therefore, the correct answer is:

Rs 513 – Rs 80 = Rs 433 a day

Now, to find the savings of the company on 10 children per day,
multiply Rs 433 by 10.

Rs 433 × 10 = Rs 4330.

Hence, the factory saves Rs 4330 per day on 10 children.

**Find Out**

**Question 15 : **In your area there are shops or
factories where young children are made to work? Talk to some of
these children. How much are they paid there?

**Answer : **
Do it by yourself. Child labour is a crime.

**Train Journey**

**Question 16 : **This train goes from New Jalpaiguri
to Guwahati. On its way, it stops at New Mal, Alipurduar and
Goalpara stations. The cost of a rail ticket to different stations
is given in the table.

Find the distance:

a. From New Mal to Guwahati _____

b. Between New Mal and Goalpara______

c. From Alipurduar to Guwahati______

d. Between New Mal and Alipurduar______

e. From Goalpara to Guwahati_______

**Answer : **

a. New Mal is 57 km from New Jalpaiguri, and Guwahati is 495 km
from New Jalpaiguri. Subtract 57 from 495 to get the distance
between New Mal and Guwahati.

495 – 57 = 438

Hence, the correct answer is 438 km.

b. New Mal is 57 km from New Jalpaiguri, and Goalpara is 366 km
from New Jalpaiguri. Subtract 57 from 366 to get the distance
between New Mal and Goalpara.

366 – 57 = 309

Hence, the correct answer is 309 km.

c. Alipurduar is 175 km from New Jalpaiguri, and Guwahati is 495
km from New Jalpaiguri. Subtract 175 from 495 to get the distance
between Alipurduar and Guwahati.

435 – 175 =

Hence, the correct answer is 320 km.

d. Alipurduar is 175 km from New Jalpaiguri, and New Mal is 57 km
from New Jalpaiguri. Subtract 57 from 175 to get the distance
between Alipurduar and New Mal.

175 – 57 = 118

Hence, the correct answer is 118 km.

e. Goalpara is 366 km from New Jalpaiguri, and Guwahati is 495 km
from New Jalpaiguri. Subtract 366 from 495 to get the distance
between Goalpara and Guwahati.

495 – 366 = 129

Hence, the correct answer is 129 km
