    Pretty simple, but hey, its all I got An Indian chief captures 3 white men and takes them into his teepee, where it is completely dark. He tells them he has 5 headbands, 3 white, and 2 red, and that he is going to put them on the men randomly, so there is 2 headbands unused. He then puts them in a line, and marches them out of the teepee, like so: ^ c b a ^ = teepee, a = first man, b = second, c = third so that the third man can see the first two mens headbands, the second man can see the first man's headband, and the first man can't see anyone's headbands. The chief tells the men that they only have one chance for any of the men to name the col…

    32, 81, 64, 25... Whats the next number? This should be really easy for most people here. I'm only posting it because it hasn't been solved at my school by anybody besides me and I wanted to gauge how hard it actually is. My school is pretty mathematically and scientifically deficient. Please post how long it took you.

    A buddhist monk makes a usual journey up the mountain. He leaves at dawn from the bottom and arrives at the top just in time to see the sunset, stopping a number of times along the road to eat and meditate. At the top he rests the whole night and leaves again the next morning at dawn. During his way down he stops along the road to meditate and eat and arrives at the bottom in time to see the sunset. At which point along the road did the monk cross at the same exact time both days?

    Well my friends math teacher gave him this list of 50 math puzzles, and he passed it along to me (since he knows I like them more). Out of the 50 I haven't solved 7 (I just got them this morning and worked on them through school), so I figured I'd post them on here for you guys to try. If you really want I'll put up all 50 later. 1. Use three 5's to make 115 2. Use four 8's to make 100 3. Use two 4's to make 24 4. Use four 7's to make 70 5. Use three 4's to make 50 6. Use three of the same number to make 28 7. Use three of the same number to make 13 I think most have done these kind of things before, but just in case I'll give some examples. For instance, Us…

    This one was on today's Mensa Calender puzzle, and while I got the answer I think it was by dumb luck. I'm not sure how it can mathetmatically be determined. "A certain girl is a very astute shopper and always liked to get the best bargain. Today she was in charge of getting party favors for a Mardi Gras party. She goes to a store and makes her arguments and is successful in her fight. However had she paid 4-cents more per hundred party favors, she would have wound up buying 5 less. How much did she pay per hundred party favors?" For some reason, I can't figure out how to get the exact total since they don't give you the amount of money she spent total, nor t…

    Woooo. This question is very mind boggling. Try it: If you use a certain formula (you do something to) on 13, you end up with 7. Under the same formula (doing the same thing), 2352 becomes 16, 246 becomes 14, 700 turns into 16, and 1030 becomes 14. What would 9304 become? And WHY? A hint for those that are struggling (don't look if you can do it yourself): [hide]Think outside of base-10 system[/hide]

    A boy is leaving his house to go to class, and as he leaves he looks in the mirror and checks the time. Since the mirror is not digital and has no numbers, he mistakes it for correct (when in actualitly it was the mirror image.) He rides his bike for 20 minutes, and when he enters the room, he looks at the clock and notices it is 2 and a half hours later then when he thought he left. What time did he arrive at class? (it might help if you draw a picture )

    Okay, I modified the riddle a bit, but if you recognize it and know the answer, please don't give it away without giving everyone a chance. ******* A princess and a witch live on an island. This island has 8 poisoned wells, numbered 1 to 8. If you drink from a well, you can only save yourself by drinking from a higher numbered well. Well 8 is located at the top of a high mountain, so only the witch (with her witchy powers) can reach it. One day they decide that the island isn't big enough for the two of them, and they have a duel. Each of them brings a glass of water to the duel, they exchange glasses, and drink. After the duel, the princess lives and the witc…

    Hey, I came across this game on FetchFido, and was wondering if any of you guys could tell me how they pull it off. I feel like the answer is looking me right in the face, then I realize I'm deluding myself into thinking I'm smarter than I actually am. Play the game and my ramblings might make sense. http://www.fetchfido.co.uk/games/voodoo_curse/voodoo_curse.htm

    I searched the forum for any of the versions of this of which I am aware and found none. If I missed it, let me know. In a certain village, it is the moral duty of every woman to shoot her husband at midnight if she determines that he has been unfaithful. If a husband is unfaithful, every woman in the village, except his wife, knows it. On day, a priestess arrived in the village, told the woman that she knew of at least one adulterer in the village, and left. 39 nights passed without incident. Then at midnight on the 40th night, several women shot their husbands. How many adulterous husbands were shot that night?
