Answer 
Let Aman's age=x
son's age=y
x=3y..............(1)
10 years ago aman's age=x-10
10 years ago son's age=y-10
x-10=5(y-10)
x-10=5y-50
x=5y-50+10
x=5y-40............(2)
substituting (1) in (2)
3y=5y-40
5y-3y=40
2y=40
y=40/2=20
x=3y=3*20=60
Aman's age=60
Son's age=20
read lessLet Aman’s son’s age be x years. Therefore, Aman’s age will be 3x years. Ten years ago, their age was (x − 10) years and (3x − 10) years respectively.
According to the question,
10 years ago, Aman’s age = 5 × Aman’s son’s age 10 years ago
3x − 10 = 5(x − 10)
3x − 10 = 5x − 50
Transposing 3x to R.H.S and 50 to L.H.S, we obtain
50 − 10 = 5x − 3x
40 = 2x
Dividing both sides by 2, we obtain
20 = x
Aman’s son’s age = x years = 20 years
Aman’s age = 3x years = (3 × 20) years = 60 years
