Let the man's age be 3x and that of his son be x.
So, 3x + 15 = (15 + x)2
X=15
Man's age=45
His son's age =15
So, 3x + 15 = (15 + x)2
X=15
Man's age=45
His son's age =15

Let his son's present age be x.
therefore his present age is 3x.
After 15 yrs.,
son's age=x+15
man's age=3x+15
According to ques.,
Man's age=2×son's age
3x+15=2×(x+15)
3x+15=2x+30
x=15
Son's present age=x=15yrs.
Man's present age=3x=3×15=45yrs.
therefore his present age is 3x.
After 15 yrs.,
son's age=x+15
man's age=3x+15
According to ques.,
Man's age=2×son's age
3x+15=2×(x+15)
3x+15=2x+30
x=15
Son's present age=x=15yrs.
Man's present age=3x=3×15=45yrs.
