A Correct answer
Explanation

Let the ages be 2x and 5x. 2x + 5x = 77, so 7x = 77, x = 11. The ages are 2*11 = 22 and 5*11 = 55.

AI explanation

Let the common multiplier be x, making Gaurav's age 2x and Rahul's age 5x. Their sum is 77, so 2x + 5x = 77, which means 7x = 77 and x = 11. Gaurav's age is 2(11) = 22 years and Rahul's age is 5(11) = 55 years. The ages are 22 years and 55 years.
