I have the following scenarios, but I am unclear on how to handle them correctly. I start off with a value like 200 and the following scenarios are:
Remove 10% from 200, and then remove a compound 20% from that value.
Remove 10% from 200, and then remove 20% from 200. I guess this is just like removing 30%, correct?
Add 10% to 200, and then remove a compound 20% from that value.
Add 10% to 200, and then remove 20% from 200.
I am also unclear on on a certain on something else because I have been given 2 different answers. If I take 100 and want to remove 10%, is it:
100 * 0.9 = 90
or
100 / 1.1 = 90.9090....
What is the difference above?
Lastly, is there a formula than can be converted into an algorithm that will handle more than removing/adding between 1 and 2 percentages (≥3)? If so, what is it?
Initial Value = 252 Remove 10% and then a 20% Compound
Based on your answer, I am doing:
252 - (252 * (10/100)) = 226.8 226.8 - (226.8 * (20/100)) = 181.44
However, they are doing:
252 * 0.9 = 226.8 226.8 / 1.2 = 189
