C Correct answer
Explanation

Let CP = 1000 per kg. MP = 1200. Sells 900g for 1200. CP for 900g = 900. Profit = 1200 - 900 = 300. Profit % = (300 / 900) * 100 = 33.33%.

AI explanation

Let the cost price of 1 gram of the good be 1, making the marked price for 1000 grams equal to 1200. The shopkeeper sells 900 grams for 1200, so the cost price for those 900 grams is 900. Using the profit percentage formula ((Selling Price - Cost Price) / Cost Price) * 100, the calculation is ((1200 - 900) / 900) * 100. This results in a net profit of 33.33%.
