18.12%
22.5%
21%
23.5% if the discounts are taken successively, 25 % if the discounts are taken at the same time. The latter is the less usual meaning of this question.
It is 100*[1 - (1 - 9/100)*(1 - 14/100)] % = 100*[1 - 0.9*0.86] % = 100*[1 - 0.774] % = 100*0.226 % = 22.6 %
The single discount that is equivalent to a series of 40 and 20 is 20.
Start with 100. 20% off leaves 80, 15% of 80 is 12, leaving 68, an overall reduction of 32%
Single trade discount versus discount series what kind of example for one or the other
5/8/20
Your question implies that the discounts are applied sequentially, that is the first is applied and then the second is applied to the reduced amount.: To work out the single equivalent discount, you need to work using the value after discount all the way through. A 15% discount can be calculated by working out 15% of the value and subtracting it, but this is also the equivalent of working out 100% - 15% of the original value, that is 85%. Similarly for the 20%, that is working out 100% - 20% = 80% of the original value. So the final value after both discounts is 80% of 85% of the original value which is 80% x 85% = 68% and represents a discount of 100% - 68% = 32%. Thus the discounts of 20% and 15% applied sequentially is equivalent to a single discount of 32%.
a single trade discount is just that one trade discount.
Describe the difference between a single trade discount versus and discount series and give an example
A single trade discount is one discount like 30% where as a series discount is more then one like 20/10/5 but can not be added together, have to be discounted seperately.
