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?

1:

29 years

2:

30 years

3:

20 years

4:

15 years

5:

10 years

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

Then, $(x+6)+4x+4 $ = $43 $

⇒ $x+10x+4 $ = $43 $

⇒ 4(x + 4) = 3(x + 10) ⇒ x = 6

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