after 10years
4x + 10 = 3 *(x+ 10)
4x+10= 3x +30
4x -3x = 30-10
x= 20
therefore father's present age = 4x
=4 * 20 = 80
son's present age = x=20
Father's present age = 4x
After 10 years,
Son's age = x+10
Father's age = 4x+10
4x+10=3(x+10)
4x+10=3x+30
4x-3x=30-10
x=20
Son's present age = 20
Father's present age =4x = 4×20=80
