A Correct answer
Explanation

Successive discounts of 15% and 10% on 100: 100 * 0.85 = 85. 85 * 0.90 = 76.50.

AI explanation

Using the equivalent discount formula for two successive discounts of a% and b%, which is (a + b - ab/100)%, the total discount is (15 + 10 - 150/100) = 23.5%. For a marked price of Rs 100, the selling price is 100 - 23.5 = Rs 76.50.
