Since you are increasing it by a certain percentage, just multiply it by (100 + percentage)/100.
Increase 163 by 12.3%:
Do the same for the rest.
In case it's a decrease, remove the percentage from 100.
This is probable really simple for most of you but I need to work something out and wondered if someone could lend a hand please.
I have a figure. 163
I need to know a 12.3% increase of 163. I don't have any other numbers you see, that's why I'm doing the sum.
7. 163 (+12.3%)
6. --- (+10.4%)
5. --- (+8.5%)
And so on... I just can't for the life of me figure out how to find the figure that 12.3% more than 163 is. I presume I need to convert into decimals or something?
Any help greatly appreciated.
