The ages of two persons differ by 16 years. 6 years ago, the elder one was 3 times as old as the younger one what is the present age of the older person in years?

A 20

B 10

C 30

D None of these

Correct Answer: Option C

Let's take the present age of the elder person = x

and the present age of the younger person = x – 16

(x – 6) = 3 (x-16-6)

=> x – 6 = 3x – 66

=> 2x = 60

=> x = 60/2 = 30
