The Eight Pieces of Money

He who had 5 loaves was entitled to 7 pieces and he who had 3 loaves to but 1. Divide the loaves into thirds and one had 15 thirds, the other but 9 thirds, or 24 thirds in all. Now as all three ate alike they had 8 thirds each. Therefore he of the 5 loaves contributed 7 parts of the stranger's meal, while the other, who had only 3 loaves or 9 thirds in all, gave but one part.

The serpent puzzle can be worked out in a number of ways by placing the head and tail at random and then endeavouring to connect them with the remaining pieces.
