Maths can be a tricky at the best of times. Even some of the most basic calculations, like working out percentages, can prove quite difficult, especially if you are attempting to work them all out in your noggin’. But there is a surprisingly simple solution to calculating percentages that you probably haven’t been taught in school, and it’s a game changer. So, what is this secret sum?
For example, if you had to try to work out 20% of 75 in your head, all you have to do is flip it around and work out 75% of 20, which is much easier, giving you the answer of 15. This super easy trick works with any set of numbers. 28% of 50 sounds like it might make your brain explode, but how about 50% of 28? 14 of course!
