    B 18 Correct Answer Incorrect Answer
    C 20 Correct Answer Incorrect Answer
    D 14 Correct Answer Incorrect Answer

    Solution

    SP of 45 sweets = Rs 40

    SP of 1 sweets = 40/45

    L = 20%

    CP = 100/80 * 40/45 = 10/9

    SP 2 = (100 + 20) / 100 * CP

    SP 2 = 120/100 * 10/9 = 4/3

    SP of Rs 4/3 sweets for 1 sweets

    SP of Rs 24 for = 24/ (4/3) = (24 * 3) / 4 = 18 sweets
