One of the most common areas of confusion and sources of mistakes in numerical reasoning questions is understanding how to apply percentage calculations to information given in a question. It is essential to understand whether you are being asked to work out a percentage change from A to B or if it\u2019s from B to A. This will determine whether the correct calculation is A \u00f7 B or A x (1-B). V\u00ed d\u1ee5:<\/p>\n
