This is very much a logic puzzle. You are shown a series of comparisons. It's the standard - if A is heavier than B, and B is heavier than C, which is the heaviest? It's easy at first - but then they put combinations of items on scales and you have to determine through algebra which would end up being the heavier item.

This is a REALLY good skill to learn, because comparative reasoning is useful in all sorts of aspects of life. You need to think of the situations as equations, so

A = 2B
2B > C

And with that sort of set of forumulas, you figure out which is the heaviest in the set.
