C Correct answer
Explanation

Cost price = 600. Selling expenses = 15% of 600 = 90. Total cost = 600 + 90 = 690. To earn 25% profit, selling price = 690 * 1.25 = 862.5.

AI explanation

Let the net cost price be C, meaning the purchase at a 10% discount results in the equation 0.9C = 600, so C = 666.67. The selling expenses add 15% to this cost, bringing the total cost to 666.67 * 1.15 = 766.67. To earn a 25% profit, the selling price must be 766.67 * 1.25 = 862.5.
