Money and Conversion of Money into Paise and Rupee

In this chapter – Money for Class 5, we will be solving problems involving money. We will learn to convert Paise into Rupees and Rupees into Paise. Let’s learn some basic facts first.

100 paise = 1 rupee

Therefore, 1 paise = One-hundredth of a rupee = \cfrac{1}{100} rupee = 0.01 rupee

Similarly, 2 paise = 0.02 rupee, 3 paise = 0.03 rupee, 4 paise = 0.04 rupee and so on.

Also, 20 paise = 0.20 rupee, 30 paise = 0.30 rupee, 40 paise = 0.40 rupee and so on.

and, 100 paise = 1.00 rupee, 125 paise = 1.25 rupee, 150 paise = 1.50 rupee, 200 paise = 2.00 rupee

We should always use 2 digits to express paise.

For example, 1 paise as 0.01, 5 paise as 0.05, 75 paise as 0.75

In this chapter we will learn how to write rupees and paise in decimals.

For example:
20 rupees 5 paise = ₹ 20.05 [We will read it as rupees twenty decimal zero five] 65 rupees 25 paise = ₹ 65.25 [We will read it as rupees sixty five decimal two five] 125 rupees 50 paise = ₹ 125.50 [We will read it as rupees one hundred twenty five decimal five zero]

Convert Paise into Rupees

To convert paise into rupees put decimal point after 2 digits from the right.

Example 1:
Convert 25 paise into rupees.

25 paise = \cfrac{25}{100} = ₹ 0.25

Example 2:
Convert 150 paise into rupees.

150 paise = 100 paise + 50 paise = ₹ 1 + ₹ 0.50 = ₹ 1.50

Example 3:
Convert 1275 paise into rupees.

1275 paise = 1200 paise + 75 paise = ₹ 12 + ₹ 0.75 = ₹ 12.75

Convert Rupees into Paise

As 1 rupee = 100 paise, so to convert rupees into paise, multiply rupee by 100. Trick: shift decimal point to two places to the right.

Example 4:
Convert ₹ 1.50 into paise.

₹ 1.50 = 1.50 x 100 = 150 paise

Example 5:
Convert ₹ 0.05 into paise.

₹ 0.05 = 0.05 x 100 = 5 paise

Example 6:
Convert ₹ 10.75 into paise.

₹ 10.75 = 10.75 x 100 = 1075 paise

Example 7:
Convert ₹ 2 \cfrac{1}{2} into paise.

₹ 2 \cfrac{1}{2} = ₹ 2 + ₹ \cfrac{1}{2} = 2 x 100 + \cfrac{1}{2} x 100 = 200 paise + 50 paise = 250 paise

Addition of Money

Example 8:
Add 8 rupees 15 paise and 12 rupees 5 paise

8 . 1 5
+ 1 2 . 0 5
2 0 . 2 0

Therefore, sum = ₹ 20.20

Example 9:
Add ₹ 525.45, ₹ 85.05 and ₹ 200.50

5 2 5 . 4 5
+ 8 5 . 0 5
+ 2 0 0 . 5 0
8 1 1 . 0 0

Therefore, sum = ₹ 811.00

Example 10:
Sanjana bought a gift for ₹ 350.75 and his brother Rohan bought a gift for ₹ 275.50. How much did they spend altogether on the gifts?

Cost of Sanjana’s gift = ₹ 350.75

Cost of Rohan’s gift = ₹ 275.50

We will add the cost of both the gifts to find the total cost.

3 5 0 . 7 5
+ 2 7 5 . 5 0
6 2 6 . 2 5

Therefore, total cost of both the gifts = ₹ 626.25

Example 11:
Rohan and Sanjana are brothers and sisters. Rohan got ₹ 825.65 as pocket money from his father. Sanjana got ₹ 75.25 more than Rohan’s pocket money. Find the pocket money got by Sanjana.

8 2 5 . 6 5
+ 7 5 . 2 5
9 0 0 . 9 0

Therefore, Sanjana’s pocket money = ₹ 900.90

Subtraction of Money

Example 12:
Subtract ₹ 135.25 from ₹ 200.75

2 0 0 . 7 5
1 3 5 . 2 5
6 5 . 5 0

Therefore, difference = ₹ 65.50

Example 13:
Subtract 42.80 from 650.20

6 5 0 . 2 0
4 2 . 8 0
6 0 7 . 4 0

Therefore, difference = ₹ 607.40

Example 14:
Rohan bought a bicycle for ₹ 965.38 and sold it for ₹ 982.56. How much did he earn?

We will subtract the selling price of the bicycle with the costs price.

9 8 2 . 5 6
9 6 5 . 3 8
1 7 . 1 8

Therefore, Rohan earns ₹ 17.18 on selling the bicycle.

Example 15:
Sanjana bought a doll for ₹ 210.40 and sold it for ₹ 10.20 less. At what price did Sanjana sold the doll?

2 1 0 . 4 0
1 0 . 2 0
2 0 0 . 2 0

Therefore, Sanjana sold the doll for ₹ 200.20.
