A single discount equivalent to three successive discounts of 10%, 5%, and 3 1/2% will be__________.
Show answer & explanation
Correct answer: C
Explanation
The correct answer is Option 3 i.e. 18.5075%.
The net effect = x + y + xy/100
The single discount of 10% and 5% = -10 - 5 + 50/100 = -15 + 0.5 = -14.5
Single discount of 14.5% and 3.5% = -14.5 - 3.5 + 50.75/100 = 18 + 0.5075 = 18.5075%
