    A 15% Loss Correct Answer Incorrect Answer
    B 25% Profit Correct Answer Incorrect Answer
    C 18% Loss Correct Answer Incorrect Answer
    D 12% Profit Correct Answer Incorrect Answer

    Solution

    ATQ,

    Let cost price of 1 liter = 100 Marked price = 100 × 1.4 = 140 Discount 32% → Selling price per “machine liter” = 140 × 0.68 = 95.2 Machine gives 15% less → actual quantity given = 0.85 liter Cost price for 0.85 liter = 100 × 0.85 = 85 Profit = 95.2 − 85 = 10.2 Profit% = (10.2 ÷ 85) × 100 = 12%
