C Correct answer
Explanation

The marked price is 3400, and a 10% discount means the selling price is 3400 - 340 = 3060. Since the gain is 220, the cost price is selling price - gain, which is 3060 - 220 = 2840.

AI explanation

The selling price is calculated by subtracting the 10 percent discount from the marked price of 3400, resulting in a selling price of 3060. Given that the gain is 220, the cost price is found by subtracting the gain from the selling price. Therefore, the cost price is 3060 minus 220, which equals 2840. The answer is Rs. 2840.
