Question

A father has double the age of his son if the total age is 49 and the difference is 31 what is the age of father and son

Answer 1

Explanation:

Let the age of son = x

then the age of father  = y

x + y = 49   --------(1)                 (Given in the question)

x - y = 31  ------(2)

(2) - (1)

2y = 18

y = 9

Put this value in (1)

x + 9 = 49

x = 40
