C Correct answer
Explanation

1600 * 0.9 = 1440. 1440 * (1 - x) = 1224. 1 - x = 1224 / 1440 = 0.85. x = 0.15 or 15%.

AI explanation

After the first 10% discount on Rs.1600, the price becomes 1600 multiplied by 0.9, which equals Rs.1440. The second discount reduces this price to Rs.1224, meaning the discount amount is 1440 minus 1224, or Rs.216. Using the percentage formula, the second discount rate is (216 divided by 1440) multiplied by 100, which equals 15%.
