>>There were two glasses: one full of milk and another one full of water. The boy came and take one spoon of milk and put it into the glass of water. Then he repeated the procedure, e.g. took a spoon of this mixture and put it back into milk. The question is: do you have now more water in milk or milk in a water?

>Let's assume two things first (since this is a mathematician doing a physics test, I tend to check the assumptions first - I have a long history with physics on that, they never state everything, there's always an unspoken assumption):

>- the glasses were not completely full, there was room for at least a spoonful in each
>- the spoon was equally full each time.

>Let's say each glass contained four spoons of liquid; after the first operation you have three spoons of milk and five spoons of 4:1 mix. After a second operation, you have four spoons of the 4:1 mix (3.2:0.8 spoons, actually) in the other, and 3+0.2 spoons of milk and 0.8 spoons of water in the first one.

>And I started writing this trying to prove you'd have more water in the milk :)

I think, this quiz would be more interesting, if I would talk about wine + water or dark beer + light beer combination :) But the person, who mixes them, would not be a boy then... :)
