Hi EZY_FR & FlyVeryHigh,
I think you both make a strong claim, but without coming cross as an expert in this sort of thing, I believe the centre of interest comes down to the word "Reasoning". What I can only imagine with that test is, it would perhaps have multi choice answers! The key with this sort of tests is "time management" and this test will be stretching your inert numerical knowledge against a pressing time factor which would allow very limited time for calculating for a solution. So in brief, its a intuitive "logic" IMHO.
