Hi

I am trying to explain how the following works. If a object costs £100 the shop increase it by 5% so it is now £105.

The shop then reduce it from £105 buy 10% in a sale and now being £94.50.

Why is this different to the original £100 and the 5% being taken of this which would be £95.

So basically why is increasing something by 5% then reducing by 10% not the same as reducing the original by 5%

I can do the math behind these calculations, im just confused how to explain why there is a difference.

regards
