Answer 1

Answer:

Step-by-step explanation:

Let the son's present age be 'x' years .

∴father's age = 4x

after ten years ,

son's age = x + 10

father's age = 4x + 10 ---------------1

But as per the sum ,

father's age = 3(x+10) ---------------2

from 1 and 2 ,

4x +10 =3x +30

x=20

hence, son's age = 20 years

           father's age = 4*20

                              = 80 years.
