A Correct answer
Explanation

Discount = Marked Price - Selling Price = x - y. Discount percentage = (Discount / Marked Price) * 100 = ((x - y) * 100) / x.

AI explanation

Using the formula for discount percentage, Discount Percentage equals Discount divided by Marked Price multiplied by 100. The discount is the difference between the marked price x and the selling price y, giving x minus y. Dividing by the marked price x and multiplying by 100 results in ((x minus y) times 100) divided by x.
