A Correct answer
Explanation

If the discount is 20%, the customer pays 80% of the marked price. Letting M be the marked price, 0.80 * M = 1600. Solving for M gives M = 1600 / 0.80 = 2000.

AI explanation

Let the marked price be x. A 20% discount means Arun pays 80% of the marked price, giving the equation 0.80x = 1600. Solving for x, we get x = 1600 / 0.80, which means the marked price is Rs. 2000.
