Question

    A shopkeeper purchases 140 kg of sugar at Rs. 55 per kg.

    He sells a portion of it at a 20% profit and the remaining at a 10% loss. If his total profit is Rs. 154, how much sugar did he sell at a profit?
    A 52 kg Correct Answer Incorrect Answer
    B 54 kg Correct Answer Incorrect Answer
    C 56 kg Correct Answer Incorrect Answer
    D 58 kg Correct Answer Incorrect Answer
    E 62 kg Correct Answer Incorrect Answer

    Solution

    Let the amount of sugar sold at a gain be x kg The amount of sugar sold at a loss = (140 – x) kg. Selling Price of sugar sold at a gain = 120% of (55×x) = 66x Selling Price of sugar sold at a loss = 90% of (140 - x) × 55 Total Cost Price = 140 × 55 = 7700 Total Selling Price = 66x + (140 - x) × 49.5 = 66x + 6930 - 49.5x  = 16.5x + 6930 Given, Total Profit = 154 So, 16.5x + 6930 = 7700+154 16.5x = 7854 – 6930 16.5x = 924 x = 56 kg
