    Answer: (3) 46%

    Explanation:-
    The successive discount of 10% and 20% = 10 + 20 – 10 x 20/100
    = 30 – 2
    = 28 %

    Then, the successive discount of 28% and 25% = 28 + 25 – 28 x 25/100
    = 53 – 28/4
    = 53 – 7
    = 44%
    Then, the successive discount of 10%, 20% and 25% is 46%.

    Hence, the answer is (3) 46%.
