C Correct answer
Explanation

Let the cost price of 1000g be 100. The dealer marks it up by 20% to 120 and gives a 10% discount, making the selling price 108. Since he uses 900g instead of 1000g, his actual cost for the goods sold is 90. The profit is 108 - 90 = 18, and the profit percentage is (18/90) * 100 = 20%.

AI explanation

Assume a cost price of Rs. 1000 for 1 kg. The dealer marks the price up by 20% to Rs. 1200 and gives a 10% discount, selling it for Rs. 1080. Since he only gives 900g, his actual cost is Rs. 900. The profit percentage is calculated as ((1080 - 900) / 900) * 100, which equals 20%.
