AddiTion And SuBTrAcTion of Money Cost of mobile phone = ` 7 6 5 0 . 5 0

To add or subtract the money, follow these steps: Money Sanya has = – ` 6 4 7 5 . 0 0
Step 1: Arrange the given amounts in columns such that the points Be Aware Money needed = ` 1 1 7 5 . 5 0

remain in one column. Regroup paise into
Step 2: Add or subtract the amounts as ordinary numbers. rupees if required. Thus, Sanya needs `1175.50 more to buy the mobile phone.

Step 3: Put a point in the sum in the points column.
Example 1: Add `70.20 and `25.45. Example 2: Add `102.75 and `225.25. Get it right!

Solution: ` 7 0 . 2 0 Solution: 1 1 Subtract `6475 from `7650.50:

+ ` 2 5 . 4 5 ` 1 0 2 . 7 5 ` 7 6 5 0 . 5 0 ` 7 6 5 0 . 5 0
` 9 5 . 6 5 + ` 2 2 5 . 2 5 – ` 6 4 . 7 5 – ` 6 4 7 5 . 0 0
` 3 2 8 . 0 0 ` 7 5 8 5 . 7 5 ` 1 1 7 5 . 5 0

Thus, `70.20 + `25.45 = `95.65 Thus, `102.75 + `225.25 = `328.00

Example 3: Subtract `423.25 from `533.50. Example 4: Subtract `109.25 from
`423.75. Think Tank Logical Thinking
Solution: 4 10 Solution: 1 13 Three friends, Dhruv, Ravi and Virat went to watch a movie. The table given below

` 5 3 3 . 5 0 ` 4 2 3 . 7 5 shows the amount of money each one had and the amount of money each spent. Find out who has
the greatest amount of money left.
– ` 4 2 3 . 2 5 – ` 1 0 9 . 2 5 Friend Amount of money Amount spent Amount Left
` 1 1 0 . 2 5 ` 3 1 4 . 5 0 Dhruv `500 `175.50

Thus, `533.50 – `423.25 = `110.25. Thus, `423.75 – `109.25 = `314.50. Ravi `750 `145.75

Example 5: Ram bought a toy for `210.50 and a pair of shoes for `579.75. How much Virat `560.50 `95.05
money did he spend in total?

Solution: 1 1 Practice Time 11B

Cost of the toy = ` 2 1 0 . 5 0
1. Add the following amounts.
Cost of the pair of shoes = + ` 5 7 9 . 7 5

Total cost of both items = ` 7 9 0 . 2 5 ` 210.50 ` 579.75 (a) ` 8 3 . 4 0 (b) ` 6 9 . 7 0 (c) ` 7 4 . 7 5 (d) ` 2 3 2 . 1 5

Thus, Ram spent `790.25 in total. + ` 4 8 . 3 0 + ` 5 1 . 2 5 + ` 7 1 . 6 0 + ` 1 9 6 . 4 5
Example 6: Sanya wants to buy a mobile phone that costs `7650.50. She has only `6475.

How much more money does she need to buy the mobile phone? 2. Subtract the following amounts.

Solution: Sanya subtracted the smaller amount from the bigger amount to check how (a) (b) (c) (d)
much more money she needs to buy the mobile phone. ` 4 2 0 . 3 0 ` 7 3 4 . 2 5 ` 4 9 6 . 7 5 ` 2 4 2 . 8 0
– ` 1 6 2 . 2 5 – ` 2 1 4 . 0 0 – ` 3 0 4 . 4 5 – ` 1 3 2 . 5 0
Teacher’s Explain that while adding/subtracting money, if one amount has only rupees and the other has rupees and
Tip paise, first put a point and two zeros after the rupee amount. Then, write the two amounts one below the
other, keeping the points in line. For example: `45 = `45.00 | `45.00 + `32.50 = `77.50.
