Step-by-step explanation:

$\huge\tt\orange{Answer}$

Let

The present age of his father be 4x

And

the present age of son be x

After 10 year his father's age will be 3 times the age of his son

Therefore we can write it like

$4x + 10 = 3(x + 10) \\ 4x + 10 = 3x + 30 \\ 4x - 3x = 30 - 10 \\ 1x = 20$

hence the age of the son will be 20 years

hence the age of the son will be 20 years and the age of the father will be

$= 4 \times 20 = 80years$
