Apophis is correct. neo, you forgot that there has to be one more team than the highest number, because teams can't play themselves. |

This forum looked rather empty, so I decided to throw together a few puzzles:
1) Last week I bought a word processor small enough to fit in my pocket. It can write in any language and also add, multiply, subtract, divide. It has a delete facility that will correct any error made and no electricity or batteries are required to operate it. Amazingly, it only cost me 25 cents. How? [Ultimanium]
2) Divide $162 (in whole $ increments) into a number of bags so that I can ask for any amount between $1 and $162, and you can give me the proper amount by giving me a certain number of these bags without opening them. What is the minimum number of bags you will require, and what are the dollar amounts in those bags? [Kirby all the way]
3) A set of football matches is to be organized in a "round-robin" fashion, i.e., every participating team plays a match against every other team once and only once.
If 21 matches are totally played, how many teams participated? [Apophis] |
