let the present age of his son be x
so his present age be 5x
After 10years
his son age=x+10
his age is 5x+10
then, according to the question:
5x+10=3(X+10)
5x+10=3x+30
5x-3x=30-10
2x=20
x=10
so the present age of his son is 10years
so his present age be 5x
After 10years
his son age=x+10
his age is 5x+10
then, according to the question:
5x+10=3(X+10)
5x+10=3x+30
5x-3x=30-10
2x=20
x=10
so the present age of his son is 10years
