B Correct answer
Explanation

A/K = 3/4. (3x+5)/(4x+5) = 10/13. 39x + 65 = 40x + 50. x = 15. Kiran's age = 4x = 60.

AI explanation

Let Aman's age be 3x and Kiran's age be 4x. After 5 years, (3x + 5) / (4x + 5) = 10/13. Cross-multiplying yields 39x + 65 = 40x + 50, which gives x = 15. Therefore, Kiran's present age is 4(15) = 60 years.
