Answer 2

Given: Saroja's collection of stamps is 25% more than that of Sarita.

To find: We have to find by what percentage sarita's collection is less than Sarah's collection.

Solution:

To determine the percentage of sarita's collection is less than Sarah's collection we have to follow the below steps as follows-

Let Sarita's collection of stamps be x.

Saroja's collection of stamps is 25% more than that of Sarita.

So, Saroja's collection is as follows-

$x +x \times \frac{25}{100} \\ x + \frac{x}{4} \\ \frac{5x}{4}$

Thus Sarita's collection is less than Saroja's collection by-

$\frac{ \frac{5x}{4 } - x}{ \frac{5x}{4} } \times 100 \\ \frac{x}{4} \times \frac{4}{5x} \times 100 \\ = 20\%$

Thus Sarita's collection is less than Saroja's collection by 20%.
