Question Paper from: SBI PO Prelims 2017

The difference between the present ages of Amit and Sushil is 6 years. The ratio between their ages after 4 years will be 3 : 4 What can be the present age of Sushil?

29 years

30 years

20 years

15 years

10 years

Solution:

Chapter Name: Problems on Ages

Let Amit's age be x years and Sushil's age = (x + 6) years.

Then, $\frac{x + 4}{( x + 6 ) + 4}$ = $\frac{3}{4}$

⇒ $\frac{x + 4}{x + 10}$ = $\frac{3}{4}$

⇒ 4(x + 4) = 3(x + 10) ⇒ x = 6

$∴$ Sushil's present age = (14 + 6) years = 20 years
