A Correct answer
Explanation

The selling price is calculated by subtracting the discount from the marked price. 20% of 550 is 0.20 * 550 = 110. Selling price = 550 - 110 = 440.

AI explanation

Using the discount formula, Selling Price equals Marked Price multiplied by (1 - Discount Rate). Substituting the values gives Selling Price = 550 * (1 - 0.20). This simplifies to 550 * 0.80, which calculates to Rs. 440.
