100 oranges are bought at the rate of Rs. 350 and sold at the rate of Rs. 48 per dozen. The percentage of profit or loss is:

Explanation

To find the percentage of profit or loss, first determine the cost price and selling price per orange. The cost price of 1 orange is Rs. 350 divided by 100, which equals Rs. 3.50. The selling price for a dozen (12) oranges is Rs. 48, so the selling price of 1 orange is Rs. 48 divided by 12, which equals Rs. 4.00.The profit per orange is Rs. 4.00 - Rs. 3.50 = Rs. 0.50. To find the profit percentage, divide the profit by the cost price: (0.50 / 3.50) x 100% = 14.27% gain.Thus, Option A is correct. Options B, C, and D are incorrect because they either miscalculate the percentage or mistakenly suggest a loss instead of a gain.
