and

Let the age of Sunil be y

1)

x = 4y -----------------------------------(1)

2)

x - 5 = 7(y - 5)-------------------------(2)

Putting the value of x in (2)

4y - 5 = 7y - 35

-3y = - 30

y = -30 / -3

y = 10

Putting the value of y in (1)

x = 40.

Hence the present age of Sushil is 40 yrs

And Sunil = 10 yrs
