Find a single discount percentage equivalent to successive discounts of 10%, 20% and 25%.
Show answer & explanation
Correct answer: B
Explanation
The correct answer is option 2 i.e. 46%
The successive discount is 10%, 20%, and 25%.
Successive discount = X + Y - (XY)/100 (Where, X = First discount and Y = Second discount)
Successive discount = X + Y - (XY)/100 = 10 + 20 - 200/100 = 28%
Again,
Successive discount = X + Y - (XY)/100 = 28 + 25 - (28 × 25)/100 = 28 + 25 - 700/100 = 46%
