Best answer

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 %.
