    Question

    Amit is offering two consecutive discounts on a

    smartphone marked priced at Rs. 18,000. The final selling price is Rs. 12,420 after applying the first discount of 8%. Determine the percentage of the second discount provided by Amit.
    A 12% Correct Answer Incorrect Answer
    B 18% Correct Answer Incorrect Answer
    C 22% Correct Answer Incorrect Answer
    D 25% Correct Answer Incorrect Answer
    E none of these Correct Answer Incorrect Answer

    Solution

    The first discount percentage offered = 8% Let, the second discount percentage offered be 'd'% Total discount percentage offered = [(18000 - 12420) /18000] × 100 = 31% If two successive discounts of 'c'% and 'd%' are offered, then total effective discount percentage offered = c + d - (cd/100) Total discount offered = 8 + d - {(8 × d/100) } = 8 + d - [(8 × d) /100] = 31 Or, 8 + 0.92d = 31 Or, 0.92d = 23 Or, d = 25
