Combining averages, ratios and percentages

Now that you have practised basic calculations, averages, ratios and percentages, you need to practise with various combinations of these types of questions. It is easier to work through any question after you have seen its answer, or after you have solved several similar questions. But when you are taking a numerical reasoning test, the questions will be mixed, so it’s important to practise a variety of questions, without being told which type of method you should use to solve it.
