The Necklace Puzzle by Sam Loyd





"A lady bought twelve pieces of chain, as shown in the border of the picture, and wished to have them made into an endless necklace of 100 links.

The jeweler said it would cost 15 cents each to cut and join a small link and 20 cents to cut and join a large link.

The question is to tell how much the lady should pay to have the necklace made.

That is all there is to it, and it is a pretty problem for the young folks."
