The age of Raju after 15 years will be 5 times his age 5 years back. How old is Raju now?

Correct option is A

Given: Raju's age after 15 years is 5 times his age 5 years ago.
Solution:
Let Raju's present age be x.
x + 15 = 5 × (x - 5)
x + 15 = 5x - 25
15 + 25 = 5x - x
40 = 4x
x = 40 / 4 = 10
Therefore, Raju is 10 years old.
