Your father is thrice your age. Five years ago, he was 4 times your age. Find both of your ages.

Answers (1)

Assume the present age of father and his doughter/son is 3x, x years respectively.

ATQ

(3x-4)/(x-4) = 4 

3x -4 = 4x - 16

x = 16 -4 =12

Hence the present age father is 36 years and his doughter/son is 12 years.
