Question

Aman age is three times his son age ten year ago he was five times his son age find their parent age

Answer 1

Let the present age of his son be x

Then, age of Aman = 3x

10 ago, age of Aman =3x-10

age of Aman' s son =x-10

According to problem, Aman will be 5 times of his son's age

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

3x-10=5x-50

3x-5x=-50+10

-2x=-40

x=40/2=20

Aman son's present age = x= 20.

Aman' s present age = 3x = 3×20 =60.
