For Competitive Exams

The sum of the ages of a son and father is 56 years. After 4 years, the age of the father will be three times that of the son. Their ages respectively are:

12 years, 44 years

16 years, 42 years

16 years, 48 years

18 years, 36 years

Explanation:

Let the present ages of son and father be x years
and (56-x) years respectively.
Then (56-x+4)=3(x+4)
or 4x =48 or x = 12
So their ages are 12 years, 44 years respectively.
