Percent calculation
« on: April 13, 2008, 00:30:09 AM »
Hello PCBHeaven community!

I have a question about the percent calculation
For example someone says that something has turn from 20 to 30.
What is the increment in percent % and how to be calculated?

Thank you for your help!

The simple method of 3s

at  20 -> 30
at 100 -> x?

x=30*100/20

=> x=150

So, percentage = X-100=50%
