Sub-topic-5:-SUBTRACTION OF MONEY-

Rule- To subtract given amounts of money ,We will follow the following steps

Step-1-Express the given amounts in figures,using decimal notation .

Step-2- Arrange the given amounts in a column in such a way that rupees part will be
under rupees column and paise will be in paise column and decimal points fall in one
column.

Step-3- Then subtract as ordinary numbers.

Step-4- After getting the difference ,put the decimal point in the decimal point’s column.

Example-1: Subtract ₹124.45 from ₹500.20

Solution- ₹ P

Step-1 500 . 20

_ 124 . 45

_______________________________

Step-2 ₹ P

499 120

500 . 20

_ 124 . 45

_____________________________

• Here we can not subtract 45 from20 ,so we are borrowing 1 from rupees place
though 1rupee=100paise. That means 100 paise is added in paise column to
20 ,now it becomes 100p+20p=120paise.
