    A trader blends two types of rice, one costing ₹60 per

    kg and the other ₹80 per kg, in a 3:5 ratio. He sells the mixture at ₹75 per kg. What is his profit or loss percentage?
    A 2% profit Correct Answer Incorrect Answer
    B 2% loss Correct Answer Incorrect Answer
    C 3.45% profit Correct Answer Incorrect Answer
    D 4% loss Correct Answer Incorrect Answer

    Solution

    Cost of 1 kg of the mixture = (3 × ₹60 + 5 × ₹80) ÷ (3 + 5)  = (₹180 + ₹400) ÷ 8  = ₹580 ÷ 8 = ₹72.5. Selling price = ₹75. Profit or loss percentage = [(75 - 72.5) ÷ 72.5] × 100 = 3.45%. Answer: c) 3.45% profit.
