Question
A man buys two varieties of sugar weighing 50 kg and 80
kg at ₹60 and ₹70 per kg respectively. He mixes the two varieties and sells the entire mixture at ₹72 per kg. what will be the overall profit from selling the mixture?Solution
Step 1: Total cost of the first variety = 50 × ₹60 = ₹3,000. Total cost of the second variety = 80 × ₹70 = ₹5,600. Total cost price of the mixture = ₹3,000 + ₹5,600 = ₹8,600. Selling price of the mixture = (50 + 80) × ₹72 = 130 × ₹72 = ₹9,360. Profit = 9,360 – 8,600 = ₹ 760
