Thread: How to find the figure from knowing the original figure and percentage increase

1. How to find the figure from knowing the original figure and percentage increase

Hello all,

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.

Thanks

2. Since you are increasing it by a certain percentage, just multiply it by (100 + percentage)/100.

Eg.

Increase 163 by 12.3%:

$163 \times \dfrac{100 + 12.3}{100} = 183.049$

Do the same for the rest.

In case it's a decrease, remove the percentage from 100.

3. That is brilliant, you're a life saver.

Thank you ever so much.
