Question

Aman age is 3 times his son's age 10 years ago he was 5 times his son's age find their present age

Answer 1

Let Aman's son's age be x
Therefore,Aman's age =3x

Before Ten Years,
Aman's age =3x-10=5x
Aman's son's age =x-10

According to the question,
3x-10+x-10=5x
3x+x-10-10=5x
4x-20=5x
-20=5x-4x
-20= -x
-20/-1=x
20=x
or
x=20

Therefore,
Aman's present age =3x
=3(20)
=60years.
Aman's son's present age =x
=20years.
