    Question

    Ashish bought some rulers at the rate of ₹180/dozen. He sold them for Rs. 24 each. His profit percentage is ______%.​

    A.

    58

    B.

    60

    C.

    62

    D.

    64

    Correct option is B

    Given:

    Cost price of rulers = Rs. 180 per dozen

    Selling price of one ruler = Rs. 24

    Find the profit percentage.

    Formula Used:

    Profit % = ProfitCost Price×100\frac{\text{Profit}}{\text{Cost Price}} \times 100​​

    Solution:

    Cost price of 1 dozen (12 rulers) = Rs. 180

    Cost price per ruler = 18012\frac{180}{12}​ = 15

    Selling price per ruler = Rs. 24

    Profit per ruler: 24 - 15 = 9

    Profit percentage: 915×100\frac{9}{15} \times 100​ = 60%
