Question

Present age of father is 42 years and that of his son is 14 years. Find the ratio of age of the father to the age of son, when son was 12 years old.

Answer 1

Two years ago, the age of the son was 12 years and the age of the father was 42 − 2 = 40 years

Required ratio = `40/12 = (4 xx 10)/(4 xx 3) = 10/3`.
