Show answer & explanation

Correct answer: D

Explanation

The correct answer is Option 4 i.e. 25.52%.

We have given the three successive discounts = 20%, 5%, and 2% 

Successive discount of x% and y% = x + y - xy/100

Successive discount of 20% and 5% = 20 + 5 - 100/100 = 25 - 1 = 24%

Successive discount of 24% and 2% = 24 + 2 - 48/100 = 25.52%

So, A single discount equivalent to three successive discounts of 20%, 5%, and 2% is 25.52%.
