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. To solve any word problem, we need to read each word carefully and select numbers carefully from the question to solve it.
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
