    items, when sold at Rs. 16 per item instead of Rs. 12 per item is Rs. 128. Total cost price of these items is Rs. 256. If the items are sold at a profit of 35%, then find the total selling price of 25 such items.
    A Rs.270 Correct Answer Incorrect Answer
    B Rs.360 Correct Answer Incorrect Answer
    C Rs.225 Correct Answer Incorrect Answer
    D None of these Correct Answer Incorrect Answer

    Solution

    Let, number of items sold be ‘x’.

    ATQ, 16 × x – 12 × x = 128

    Or, 4x = 128

    So, x = (128/4) = 32

    Cos price of each item = (256/32) = Rs. 8

    Selling price of an item when sold at a profit of 35% = 1.35 × 8 = Rs. 10.8

    So, the total selling price of 25 items sold at 35% profit = 25 × 10.8 = Rs. 270
