C Correct answer
Explanation

Let ages be 7x and 9x. 9x - 7x = 7, so 2x = 7, x = 3.5. Kiran's age is 7x = 7 * 3.5 = 24.5.

AI explanation

Let the common factor for their ages be x, so Kiran's age is 7x and Bineesh's age is 9x. The difference is 9x minus 7x equals 7, which gives 2x equals 7 and x equals 3.5. Kiran's age is 7 multiplied by 3.5, which is 24.5.
