    Question

    A merchant buys 150 books for ₹200 each and sells them at ₹250 each. Calculate the profit percentage.

    A.

    25%

    B.

    15%

    C.

    25.5%

    D.

    35%

    Correct option is A

    Given:

      Cost price of each book = ₹200

      Selling price of each book = ₹250

      Number of books = 150

      Formula Used:

        Profit per book = Selling Price - Cost Price

        Total Profit = Profit per book × Number of books

        Profit Percentage =Total Profit  Total Cost Price\frac{\text{Total Profit }}{\text{ Total Cost Price}}​× 100

        Solution:

          Profit per book = ₹250 - ₹200 = ₹50

          Total Profit = ₹50 × 150 = ₹7500

          Total Cost Price = ₹200 × 150 = ₹30,000

          Profit Percentage =750030000\frac{7500}{30000} × 100 = 25%

          Thus, the profit percentage is 25%.
