A trader mixes two types of sugar costing ₹42/kg and
₹60/kg in the ratio 3:2. He sells the mixture at ₹55/kg. What is his percentage profit?Solution
Cost price of the mixture per kg = (3 × ₹42 + 2 × ₹60) / (3 + 2) = (₹126 + ₹120) / 5 = ₹246 / 5 = ₹49.2. Profit = Selling price - Cost price = ₹55 - ₹49.2 = ₹5.8. Profit percentage = (₹5.8 / ₹49.2) × 100 ≈ 11.8% .
