$\sf\underline{Step-by-step \: explanation}$

Question Correction : Sumit is 3 times as old as his son. 5 years later he shall be 2.5 times as old as his son. Find their present ages.

Let Sumit's son's age be x

Then; Sumit's age will be, 3x

Five year later,

Given,

He will be 2.5 times of his son.

Acc. to the question,

3x + 5 = 2.5 (x + 5)

3x + 5 = 2.5x + 12.5

3x - 2.5x = 12.5 - 5

0.5x = 7.5

x = 15

Hence, there present ages are,

Son = ${\huge{\sf{\boxed{\boxed{15 \: years}}}}}$

Sumit = ${\huge{\sf{\boxed{\boxed{45 \: years}}}}}$
