    B.

    48.05%

    C.

    49.36%

    D.

    44.35%

    Correct option is A

    Given:

    Two successive discounts: 29%, 18% and 9%
    Formula Used:
    Single Discount = 1(1d1100)×(1d2100)×(1d3100).1 - (1 - \frac {d_1}{100}) × (1 - \frac{d_2}{100}) × (1 - \frac{d_3}{100}).​​
    Solution:
    Single Discount = 1 - (129100)×(118100)××(19100)(1 - \frac {29}{100}) × (1 - \frac{18}{100})× × (1 - \frac{9}{100})​​
    Single Discount= 1 - 0.71 × 0.82  ×  0.91
    Single Discount= 1 - 0.529802
    Single Discount = 0.470198
    Discount = 47.02%
