Question

The ratio of Fatima’s income to her savings is 4 : 1. The percentage of money saved by her is :

(a) 20% (b) 25% (c) 40% (d) 80%

Answer 1

(a) 20%

Let assume the ratio if Fatima’s income to her savings be 4y : 1y.

Then, the percentage of money saved by her is = (her savings/(income + savings)) × 100

= (1y/4y + y) × 100

= 100/5

= 20
