In Paul's kitchen a sugar bowl and a salt bowl are placed side by side.
These two containers have the same size, the same shape and their contents reach the same level.
Paul, who is a bit of joker, takes a full spoon of sugar from the sugar bowl and puts it into the salt bowl. Then he mixes the whole.
On hearing his mother's coming, quickly he puts a spoon of this mixture in the sugar bowl, in order to have the same level in each of the containers.
Is there now more salt in the sugar bowl than sugar in the salt bowl? Explain your answer.
