**Solutions: **Let us say, the present age of Suprim is *x* years.

Three years ago, Suprim’s age was (*x* – 3) years.

Five years after, his age will be (*x* + 5) years.

Given, the sum of the reciprocals of Suprim’s ages 3 years ago and after 5 years is equal to 1/3.

∴ 1/*x*-3 + 1/*x*-5 = 1/3

*(x*+5+*x*-3)/(*x*-3)(*x*+5) = 1/3

(2*x*+2)/(*x*-3)(*x*+5) = 1/3

⇒ 3(2*x* + 2) = (*x*-3)(*x*+5)

⇒ 6*x* + 6 = *x*^{2} + 2*x* – 15

⇒ *x*^{2} – 4*x* – 21 = 0

⇒ *x*^{2} – 7*x* + 3*x* – 21 = 0

⇒ *x*(*x* – 7) + 3(*x* – 7) = 0

⇒ (*x* – 7)(*x* + 3) = 0

⇒ *x* = 7, -3

As we know, age cannot be negative.

Therefore, Suprim’s present age is 7 years
