C Correct answer
Explanation

The selling price after the first 15% discount is 10,000 * 0.85 = 8,500. To reach 7,650, the second discount x must satisfy 8,500 * (1 - x/100) = 7,650, which simplifies to 1 - x/100 = 0.9, meaning x = 10.

AI explanation

After the first 15% discount, the price becomes 85% of 10,000, which is 8,500. The second discount of x percent brings the price down to 7,650, meaning 8,500 multiplied by the quantity 1 minus x divided by 100 equals 7,650. Solving for x gives x equals 10, resulting in 10 percent.
