Question

the sum of the ages of son and father is 56 years. after 4 years the age of son will be one third of his father .find the age of the father

Answer 1

Answer:

Let x be the present age of the son.

So father's age will be 56-x

After 4 years the age of the father will be 3 times that of his son

$(56 - x + 4) = 3(x + 4)$

$56 - x - 3x - 12 + 4 = 0$

4x = 56 -8 = 48

x = 12

The age of the son is 12 years.
