Answer:  (3) 46% 

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

Then, the successive discount 28% & 28% = 28 + 25 – 28 x 25/100
 = 53 – 28/4
 = 53 – 7
 = 46%

Then, the successive discount of 10%, 20% and 28% is 46%.

Hence, the correct answer is (3) 46%.
