Subtraction of Money

We can subtract or fi nd the diff erence of two amounts. Let us learn how to subtract
money.

For the subtraction of money, we follow these steps:

Step 1: Write the given amounts in fi gures.

Step 2: Convert the amounts into paise.

Step 3: Find the diff erence in paise.
Step 4: Convert the diff erence into rupees and paise.

Let us learn through examples.

Let's Try

Example 1: Subtract 13 rupees 75 paise from 87 rupees 97 paise.

Solution: ` 87.97 = 8797 paise 8797 paise

` 13.75 = 1375 paise – 1375 paise

Hence, diff erence = 7422 paise = ` 74.22 7422 paise
