    Answer: (1) 28 %

    Explanation:-
    Given-
    First discount is 10 %  & second discount is 20 %.
    Successive discount = ?

    Formula-
    Successive discount = X + Y – X  x Y /100
    Where, X  &   Y are two discount.

    Then, Successive discount of 10 %  & 20 % = 10 + 20 – 10 x 20 /100
    = 30 – 2
    = 28 %

    Then, the 10% discount and then 20% discount in succession is equivalent to total discount of 28 %.

    Hence, the answer is (1) 28 %.
