The ratio of the present ages of a mother and a son is 4 : 1. Fourteen years from now, the ratio of their ages will be 2 : 1 The present age (in years) of mother is:

28

Lets assume, present age of mother is 4x and son is x

Given, \(\frac{4x + 14}{x + 14}\) = \(\frac{2}{1}\)

           ⇒ 4x + 14 = 2x + 28

           ⇒ x = 7

Present age of mother = 28 years
