Let us consider some of the word problems on subtraction of money. We have solved the problems in both the methods i.e., with conversion into paise and without conversion into paise.
Worked-out examples on subtraction of money:
1. Subtract Rs. 73.08 from Rs. 114.75
Method 1 (with conversion into paise):
Rs. 73.08 = 7300 paise + 08 paise = 7308 paise
Rs. 114.75 = 11400 paise + 75 paise = 11475 paise
- 7308 Paise
Therefore, difference of Rs. 73.08 from Rs. 114.75 = 4167 Paise = Rs. 41.67
Method 2 (without conversion into paise):
- 73. 08
(i) Rs. and Paise are arranged in columns with decimal point between them.
(ii) Smaller amount is placed under the larger amount.
(iii) Subtraction is made as ordinary subtraction.
(iv) 75 paise - 08 paise = 67 paise
(v) Rs. 114 - Rs. 73 = Rs. 41
Therefore, difference of Rs. 114.75 - Rs. 73.08 = Rs. 41.67
2. Ron has Rs 100 with him. He spent Rs 79 in purchasing a water bottle. How much money is left with him?
Total amount of money Ron had Rs 100.00
Amount of money he spent - Rs 79.00
Amount of money is left with him Rs 21.00
3. Mary had Rs 575 in her piggy bank. She took out Rs. 320 from it. How much money is left in her piggy bank?
Total amount of money in the piggy bank Rs 575.00
Amount of money taken out - Rs 320.00
Amount of money left in the piggy bank Rs 255.00
