C Correct answer
Explanation

Let MP = 2160. First discount 10% means price becomes 2160 * 0.9 = 1944. If we know the final price is 1654.40, we can find the second discount rate. Both I and II are required.

AI explanation

To find the second discount, you must calculate the price after the first discount and compare it to the final price paid, requiring the marked price, the first discount percentage, and the final amount paid. Statement I provides the marked price of Rs. 2160, and statement II provides the first discount of 10%, which allows you to calculate the intermediate price as 2160 minus 10 percent of 2160, resulting in Rs. 1944. Comparing this to the final price of Rs. 1654.40 gives the second discount amount, so only statements I and II together are sufficient to determine the answer.
