You can put this solution on YOUR website! Let son's age = x
father's age =3x
..
After 15 years
son's age = x+15
father's age = 3x+15
..
3x+15=2(x+15)
3x+15=2x+30
x=15.. son's age now
Father's age now = 3x = 45
You can put this solution on YOUR website! let the present age of son be x
and the present age of father be 3x
after fifteen years
(3x+15)=2(x+15)
(3x+15)=(2x+30)
3x+15-2x-30=0
x-15=0
x=15
father age will be 3*15=45
