Answer 2

Let the present age of son be x.

Let the present age of son be x.Present age of father=4x.

Let the present age of son be x.Present age of father=4x.Now,

Let the present age of son be x.Present age of father=4x.Now,Ten year hence his father age will be 3 times his son.

4x + 10 = 3(x + 10)

4x + 10 = 3x + 30

4x - 3x = 30 - 10

x = 20

So,

So,Son age is=20 years

So,Son age is=20 yearsAnd father age is=4×20=80 years
