Question
A retailer claims that he is selling tomatoes at ₹30
per kg, which cost him ₹32 per kg, but he gives only 800 g instead of 1000 g. What is the percentage of his profit? (Rounded off to two decimal places)Solution
The retailer sells 800 g of tomatoes for ₹30, so his effective selling price per kg is ₹30 ÷ 0.8 = ₹37.50. His cost price is ₹32 per kg. So, profit per kg = ₹37.50 - ₹32 = ₹5.50. Profit percentage = (5.50 ÷ 32) × 100 = 17.19%
