Correct Answer

Explanation

If the age of Rohan is represented by y,
 and Rahul is 15 years older than Rohan, meaning his age is y+15,
 then Rahul's age 5 years ago was y+15-5. Rohan's age 5 years ago was y-5.

 If we are given that 5 years ago, Rahul was 3 times as old as Rohan, 
we can set up the equation (y+15-5)=3(y-5). 

Solving this equation gives us y+10=3y-15, or 2y=25,
 which means Rohan is 12.5 years old. This means that Rahul is 27.5 years old.
