I need to reverse the effect of subtracting 4% from a large anmount of numbers.
One example: There was subtracted 4% from 100 making it 96. What kind of formula would make it 100 again?
Above is just an example. For the vast majority of the numbers I only know that 4% was subtracted. Something like this 100 - ((100 / 100) x 4))
Is it possible to do something like we do with Danish VAT:
- Subtract 20% VAT: 100 x 0.80 = 80
- Add the 25% VAT back: 80 x 1.25 = 100
