Suppose Rohit went to purchase a book of worth 100 rupees. He had money in Rs. 50 and Rs. 10 notes. How many notes of Rs. 50 and Rs. 10 he has to pay to purchase the book?

Addition and Subtraction of Money


Let us take an example.

Monty bought a packet of crayons Rs.25mdan ice-cream for Rs. 12. How much money did he spent?


Here, you can simply do the addition.

He spent Rs. 37.

Let us take another example.

Add 25 rupees 45 paise and 32 rupees 25 paise. In this case, we have to add rupees and paise separately.

Step 1. First add the paise

Step 2. Then add rupees.


     25 rupees                        45 paise

+  32 rupees                        25 paise


    57 rupees                          70 paise


So, you will get 57 rupees 70 paise or Rs. 57.70



Let us take an example.

Aditi went to market. She had Rs. 75. She bought a geometry box of Rs. 32. How much rupees she is left with?

Aditi had Rs. 75. She purchased a geometry box of Rs. 32. So, we have to subtract Rs.32 from Rs. 75 to get the money Aditi had.

   75 rupees

 - 32 rupees


    43 rupees


She is left with Rs. 43.


Let us take another example.

Can you subtract 25 rupees 30 paise from 45 rupees 40 paise.

It is same like addtion. Subtract the paise first. Then, subtract rupees.

  45 rupees             40 paise

-25 rupees             30 paise


 20 rupees              10 paise

So, you will get 20 rupees 10 paise or Rs. 20.10


Let us learn how to convert rupees into unit of paise and paise in unit of rupees.

We have learnt that Rs. 1 = 100 paise

Therefore, to convert rupees to paise multiply amount in rupees by 100.

For example:

Rs. 5 \[=\text{ 5 }\times \text{ 1}00\text{ p }=\text{ 5}00\text{ p}\]


Rs. 12.50 \[=\text{ 12}.\text{5}0\text{ }\times \text{ 1}00\text{ }=\text{ 125}0\text{ p}\]

For conversion of paise into rupees, divide amount in paise into rupees.

For example:

1635 paise = Rs.\[\text{1635 }\div \text{ 1}00\] = Rs. 16.35
