C Correct answer
Explanation

Simple interest on 4000 for 2 years is 800, so rate = 10%. For 6000 at 10% for 6 years, interest = (6000 * 10 * 6) / 100 = 3600. Amount = 6000 + 3600 = 9600.

AI explanation

First, find the simple interest rate from the first scenario where the interest is 4800 minus 4000, equaling 800, so the annual interest is 400. The rate is calculated as (400 divided by 4000) multiplied by 100, resulting in 10 percent. For the principal of Rs. 6000 over 6 years, the interest is (6000 multiplied by 10 multiplied by 6) divided by 100, which equals Rs. 3600, and adding this to the principal gives Rs. 9600.
