Hi Karmanpreet!

The solution to your question:

Let Preet’s present age be P and Abdul’s present age be A.

Given:

P = A + 6

Six years ago:

P − 6 = 4(A − 6)

Substitute P = A + 6:

(A + 6) − 6 = 4(A − 6)

A = 4A − 24

3A = 24

A = 8

So, Abdul is 8 years old.

Preet = A + 6 = 14

Present ages:

Preet = 14 years

Abdul = 8 years

Hope you got the answer, thank you!
