A Correct answer
Explanation

First, find the time from the first case: Simple Interest = 725 - 500 = Rs. 225. Using SI = P×R×T/100, we get 225 = 500×9×T/100, so T = 5 years. Now for Rs. 600 at 11% for 5 years: SI = 600×11×5/100 = Rs. 330. Amount = 600 + 330 = Rs. 930. The key insight is that time remains the same in both scenarios.
