Question= Amans age is three times his son age . Ten years ago he was five times his sons age . find their present ages.

Answer»

Answer:

Let the son age be x and the man age be 3x.

Before TEN YEARS,the son' s age was x-10 years.

The father age was 3x-10 years.

It is given that ten years AGO A man age was five times his sons age

=3x-10=5(x-10)

=3x-10=5x-50

=3x-5x=(-50)+10

=-2x=-40

=x=40/2=20

Hence AMAN present age is 3x=20×3=60 years

And his son age is x=20 years
