[Q] Choose any one of the below
(a) 52
(b) 25
(c) 35
(d) 53

Solution

Answer    (c)
Explanation
----
Let the present age of P and Q be 3x and 4x respectively.

Ten years ago, P was half of Q's age
=> (3x – 10) = 12(4x – 10)
=> 6x – 20 = 4x – 10
=> 2x = 10
=> x = 5

total of their present ages = 3x + 4x = 7x = 7 × 5 = 35
