B Correct answer
Explanation

Let Rahul's age be x, so his father's age is 3x. After 5 years, (x+5) + (3x+5) = 66, which simplifies to 4x + 10 = 66, so 4x = 56 and x = 14. Rahul is 14 and his father is 42.

AI explanation

Let Rahul's present age be x, making his father's present age 3x. After 5 years, the sum of their ages will be (x + 5) + (3x + 5) = 66. Solving the equation 4x + 10 = 66 yields 4x = 56, so x = 14. Therefore, their present ages are 14 years and 42 years.
