Subtraction of Rupees and Paise

To subtract rupees and paise, we write rupees in one column and paise in the

other column. For example, to subtract ` 2.40 from ` 3.50, make columns as
shown:

` p
Step 1: Subtract the paise.
3 50
50 – 40 = 10
– 2 40
Step 2: Subtract the rupees.

1 10 3 – 2 = 1

So, ` 3.50 – ` 2.40 = ` 1.10.

Let’s take another example.

Subtract ` 80.55 from ` 110.90.

` p
8 10 Step 1: Subtract the paise.
110 90
90 – 55 = 35
– 80 55
