    Solution

    ATQ,

    Cost price of 2 dozen donuts = Rs. 120

    Selling price of 18 donuts = 18 × (72/12) = Rs. 108

    Selling price of 6 donuts = 6 × (48/12) = Rs. 24

    Selling price of 24 donuts = 108 + 24 = Rs. 132

    Profit earned on selling 24 donuts = 132 – 120 = Rs. 12

    Profit percentage = (12/120) × 100 = 10%
