A trader buys 150 kg of rice at ₹20 per kg and 100 kg
of rice at ₹25 per kg. He mixes them and sells the mixture at ₹27 per kg. What is his overall profit or loss percentage?Solution
Cost of 150 kg rice = 150 × 20 = ₹3,000. Cost of 100 kg rice = 100 × 25 = ₹2,500. Total cost = ₹3,000 + ₹2,500 = ₹5,500. Total quantity = 150 + 100 = 250 kg. Selling price = 250 × 27 = ₹6,750. Profit = Selling price - Cost price = ₹6,750 - ₹5,500 = ₹1,250. Profit percentage = (Profit / Cost price) × 100 = (1,250 / 5,500) × 100 = 22.73%. Correct option: c
