D Correct answer
Explanation

Selling price = Marked Price * (1 - discount/100). 13.20 = MP * (1 - 0.12) = MP * 0.88. MP = 13.20 / 0.88 = 15.

AI explanation

Using the discount formula, Selling Price = Marked Price * (1 - Discount/100). Substituting the given values results in 13.20 = Marked Price * (1 - 12/100). This simplifies to 13.20 = Marked Price * 0.88, so the Marked Price equals 13.20 / 0.88 = 15. The marked price is Rs. 15.
