Addition of money

The steps to add moneys are the following:

• Add the paise. If the paise is more than 100 then subtract 100 from it and add 1 to the rupees.
• Add the rupees.

Example 1:

Add ₹25.75 and ₹15.35.

Solution:

Step 1: Add 75p and 35p.

   75p + 35p = 110p

   The total paise is more than 100. Therefore, subtract ₹100 from ₹110.

   110 – 100 = 10

Step 2: Add ₹25, ₹15 and ₹1.

   ₹25 + ₹15 + ₹1 = ₹41

   Therefore, the sum is 41.10.

Subtraction of Money

The steps to subtract moneys are the following:

• Subtract the paise. If the paise is negative then add 100 to it and subtract 1 from the rupees.
• Subtract the rupees.

Example :

Subtract 15.75 from 17.35.

Step 1: Subtract 75p from 35p.

   35p – 75p = −40p

   The total paise is negative. Therefore, add 100 to it.

   100 + (−40) = 100 – 40 = 60

Step 2: Subtract ₹17 from ₹15.

   ₹17 - ₹15 = ₹2
