At present, father’s age is 4 times more than that of his son. 6 years ago father’s age was 10 times more than that of his son. What is the present age of father and son?

A 36 and 9 years

B 32 and 8 years

C 40 and 10 years

D 48 and 12 years

Solution

Correct Answer: Option A

(F-6) = 10(S-6)

=> 4S - 6 = 10S - 60

=> 6S = 54

S = 9, F = 36
