C Correct answer
Explanation

Selling at 450 with 10% loss means 0.9 * CP = 450, so CP = 500. To gain 10%, the new SP is 1.1 * CP = 1.1 * 500 = 550.

AI explanation

Using the cost price formula for a loss, the cost price is 450 divided by 0.90, which equals 500. To find the new selling price for a 10 percent profit, multiply the cost price by 1.10 to get 550. The cost price is 500 and the required selling price is 550.
