Hello everyone :]
i like to browse around the web searching for math problems and puzzles that are quite difficult, and nearly unsolvable. they are interesting brain excersises, some of which i can solve and some of which i cant. This particular one I can't figure out how to go about solving it, so I will post it here as both a challenge and a question to anyone willing to try it.
here it is:
A man has 4967 coins. Suppose he divides those coins into several coin pouches so that if you ask for any whole number of coins between 1 and 4967, he can give you the proper amount by giving you a certain number of pouches. What is the minimum number of pouches required for him to do this?
note: i did NOT make this up, i found it on the web.
even if you dont know the answer, any tips or advice on how to start this would be appreciated :]
