Rate A Puzzle
Due to rumours that there was a world shortage of chewing gum, everyone was stocking up on packs. By the time I'd got to the store, they had sold out!
However, there were two people at the till who had already bought 4 and 5 packs respectively and they kindly offered to share their packs with me.
After the sharing, we all had the same number of packs each and I paid them $9 for my packs. How did they share the $9 between them?
