Home > Logic > Weights and Scales
These problems relate to objects of different weight, and using a balanced scale to determine the odd item, be it a false coin, or an under-filled sack of grain. (Usually it's coins though)
d3: Select six weights from a set of weights (1, 2, …, 26) grams in such a way that any two subsets of the six add up to distinct total weights.

Bonus-d4: Prove that no similar subset of 7 exists.
