[Q] The sum of the present ages of a son and his father is 60 years. Six years ago, father's age was five times the age of the son. After 6 years, what will be son's age?
(a) 30 years
(b) 20 years
(c) 40 years
(d) 10 years
Solution
Answer    (b)
Explanation
----
Let the present age of the son = x, then
Present age of the father = 60-x

Six years ago father's age was 5 times the age of the son
=> (60-x)-6 = 5(x-6)
=> 84 = 6x
=> x = 846 = 14

Son's age after 6 years = x + 6 = 14 + 6 = 20 years
