A Correct answer
Explanation

Let ages be 3x and 2x. 3x - 2x = 7, so x = 7. Arun's age = 3x = 21.

AI explanation

Let the common multiplier be x, so Arun's age is 3x and Vijay's age is 2x. The difference in their ages is 7 years, giving the equation 3x - 2x = 7 and x = 7. Arun's present age is 3(7) = 21 years. Arun is 21 years old.
