[Q] 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 are their present ages of the elder person
(a) 50
(b) 30
(c) 20
(d) 40

Solution

Answer    (b)
Explanation
----
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 = 602=30
