Start with 100. 20% off leaves 80, 15% of 80 is 12, leaving 68, an overall reduction of 32%

I presume you are asking for the equivalent single percentage discount when first 50% is applied, then 10%, then 10%, then 5% then 5%, ie 95% of 95% of 90% of 90% of 50% of the original price is being paid, so the total discount is 100% - this: 95% of 95% of 90% of 90% of 50% = 95/100 x 95/100 x 90/100 x 90/100 x 50/100 = 3655125/10000000 = 36.55125 % ≈ 36.55 % So the discount is approx 100% - 36.55% = 63.45 %
A single letter. 33.3% equals 1/3. 1/3 of the word 'eel' would be one letter.
it means that it kills every single organism that it comes into contact with/infects. if you're talking about a disease, then it means that if you get it, you will die- no exceptions

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.
18.12%
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 %
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%.
Single trade discount is the percentage off an individual good during an individual purchase. Discount series are several discounts given at a duration in time.
a single trade discount is just that one trade discount.

Single trade discount versus discount series what kind of example for one or the other
The single discount that is equivalent to a series of 40 and 20 is 20.
