Hi MEG@DK
There are a few books on amazon for numerical reasoning which reflect the kind of questions I had in 2012. It's pretty basic maths, no algebra as far as I remember. Fractions, percentages, ratio, area of rectangles and circles, Pythagoras, long division. Basic GCSE stuff.
Example: A man buys four fence posts for £40.75. They were reduced in a sale by 17.5%. How much was one fence post before the sale.
There is around 25 questions to be completed in a tight time frame so just practice lots of questions with about 30 seconds per question.
Does anyone have some more info regarding the multi tasking aptitude test with the ECAM and TCAS? Any tips would be much appreciated!
