Question

A man is four times as old as his son. in four years' time, he will be three times as old. what are there ages now?

Answer 1

Let the present age of man be 4x and age of the son be x

After 4 years

age of son will be x + 4 and age of the man will be 4x + 4

4x + 4 = 3(x +4)

4x + 4 = 3x + 12

X = 8

Hence the present ages of man and son will be 32 and 8 years respectively
