Answer»

(a) Present age of father = 42 years

Present age of son = 14 years

Required ratio = 42/14 = 3/1 = 3 : 1

(b) 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 x 10)/(4 x 3) = 10/3

= 10 : 3

Required ratio = 52/24 = (4 x 13)/(4 x 6) = 13/6 = 13 : 6

(d) 12 years ago, the father was 30 years old, At that time age of son = 14 – 12 = 2 years

Required ratio = 30/2 = 15/1 = 15 : 1
