(a) 20%
(b) 25%

Solution:

Given, the ratio of Fatima’s income to her savings is 4 : 1

We have to find the percentage of money saved by her.

Let the income be 4x

Let the savings be x.

Percentage of money saved = savings/(income+savings) × 100

= x/(4x+x) × 100

= (x/5x) × 100

= (1/5) × 100

= 20

Therefore, the required percentage is 20.
