Let’s Attempt

Example 1: Convert the following amounts into paise.
(a) ` 43.95 (b) ` 0.05 (c) ` 19.05

Solution: (a) ` 43.95 = (43.95 × 100) p = 4395 p (b) ` 0.05 = (0.05 × 100) p = 5 p
(c) ` 19.05 = (19.05 × 100) p = 1905 p

Example 2: Convert the following amounts into rupees.
(a) 4635 p (b) 750 p (c) 4 p (d) ` 75 and 25 paise

Solution: (a) 4635 p = ` 4635 = ` 46.35 (b) 750 p = ` 750 = ` 7.50
100 100

(c) 4 p = ` 4 = ` 0.04. (d) ` 75 and 25 paise = ` 75 + 25 p
100
= ` 75 + ` 25 = ` 75 + ` 0.25 = ` 75.25
100

after two decimal places from right. Decimals are placed one under the other in columns.
Let’s learn through examples.

Let’s Attempt

Example 1: Add ` 39.75 and ` 56.48. Fact-o-meter
Solution: Adding column-wise, we get: � Sum in p (paise) column
cannot exceed two digits.
1 1 1 � Carry over the third digit to
` 3 9 . 7 5 the left into ` column.

+ ` 5 6 . 4 8
` 9 6 . 2 3 Hence, the required sum is ` 96.23
