C Correct answer
Explanation

CP = 450, Profit = 12%. Selling Price = 450 * 1.12 = 504. SP = Marked Price * (1 - Discount%). 504 = MP * 0.9. MP = 504 / 0.9 = 560.

AI explanation

The shopkeeper makes a 12% profit on the cost price of Rs. 450, so the selling price is 450 * 1.12 = Rs. 504. This selling price is achieved after allowing a 10% discount on the marked price, which means 504 represents 90% of the marked price. The marked price is therefore 504 / 0.9, which equals Rs. 560.
