The peresent age of the father and the son are in the ratio of 8:3. After 12 years the ratio of their ages will be 2:1. What is the sum of the present age of the father and the son ?

Answer»

66 years



Let the present age of the father be
 'x' and that of the son be 'y'. Then x/y = 8/3
3X = 8Y
 Further, x + 12/y + 12 = 2/1
 ∴ x + 12 = 2y + 24
