Hey user , here's your answer ...
let present age of Sonu be x
3 years ago = 3+x
5 years later = 5+x
1/3+x + 1/5+x = 1/3
5+x+ 3+x / 3+x * 5+x = 1/3
8+2x /15 + 5x + 3x + x^2 =1/3
24 +6x = x^2 + 8x + 15
24-15 = x^2 + 2x
x^2 +2x - 9 = 0
solving it for zeroes ,
you will get the value of x =present age .
Hope it will help you :)
