Answer 2

Given:

A boy saves Rs 5.75 daily

To find:

The least number of days to save exact number of days.

Solution:

Convert rupees into paise.

Rs 5.75 = 575 paise

The exact number of rupees will be a multiple of 100 (paise).

Take LCM of 575 and 100.

575 = 5 × 5 × 23

100 = 2 × 2 × 5 × 5

LCM of 575 and 100 = 5 × 5 × 2 × 2 × 23

                                  = 2300

The boy saves 2300 paise.

Divide 2300 by 575.

$\frac{2300}{575} =4$

Therefore the least number of days to save exact number of rupees is 4.
