Yea, that was my guess also... all of its features are not unique, making it unique, since all of the others have a unique feature....lol
If all seven are boys, then saying "half are boys" is technically true. The other half are ALSO boys. We are meant to simply assume that the other half are girls, when in fact the riddle makes no mention of this. ---------- A fellow lives on the tenth floor of his apartment building. He gets in an elevator and rides it all the way down every morning to work. In the evening, he gets backin the elevator. Sometimes he rides it all the way up, but most of the time he rides it only to the 6th floor and then takes the stairs the rest of the way up. Why?
You have a round birthday cake. With three straight slices of a knife, divide the cake into 8 equal pieces.
can i use two slices to cut it into fourths and then slice it through the middle horizontally to make 8 with my 3rd slice?
cut the cake halfway up laterally, creating 2 equal round pieces then, use 1 slice on each piece that is left thats 8 pieces
I think he is right codell. The Slicer could be 20 foot long for all we know. All you have to do is line up the four pieces he created in a straight line and slice em. That gives you eight. The key is to take them out of the circle formation.
Ok, this was emailed to me at work, and after seeing the "expertise" we have here I thought I'd post it to see if anyone can come up with a logical answer. I don't know the answer myself so we'll see what everyone can come up with. Half of the population of a village are liars and the other half are truth tellers. The liars always lie and the truth tellers always tell the truth. You cannot tell the difference between who is lying or who is telling the truth by their looks. A stranger (refer to that person as A), walks into the village, and asks someone in the village (refer to that person as B), "are you a liar or a truth teller?" But while B was answering, A walked away without hearing B's answer. Meanwhile, A saw two other persons (C & D) who were standing close enough to hear B's answer. A asked C & D what B had said. C mention that B said he was liar. D said that B indicated he was a truth teller. Based on the above mentioned story and without asking B any more questions, A figured out what B was and who was lying or telling the truth amongst C & D. How did A figure it out? How did he know?

Seems like part of the riddle is missing. There is a riddle similar to this one which goes or similarly: A man walking down a trail comes to a fork in the trail. One trail leads to death and one is the way the man needs to go to live. The trail is blocked by two, talking stones that can tell him the right way he needs to go to live. One rock always tells the truth while the other is always lying. He can ask one question to either of them to find the right way to go. How or what does he ask? Correct answer: The correct answer is to ask either of them: "If I ask the other rock what path I should take (or what path leads to me living) what will be their answer?" If you ask that, whatever path they answer will be the wrong one. Either the one you asked lied about the other's truth, or that one tells the truth about the other's lie. Either way, your answer is the path you don't want. Just take the other. Then again, looking at your riddle it looks like this may be the right answer for it as well.
Generally, I've seen these called "knight and knave" problems -- knights never lie, knaves always lie. As Lil Pun said, I think there's something missing. Regardless of whether B is a liar or a truth-teller, he'll answer A's question with "I am a truth-teller." Therefore, C is a liar and D is a truth-teller. However, this doesn't help you determine what B is. (P.S. wizkid's 23 prisoner problem is evil. It does have a non-trick, strictly logical answer, however.)
Here is a riddle I found and do not know the answer to either but I haven't really tried to figure it out. A man gave his young son the following challenge. He offered his son R1000 if the son could accomplish the following task. The father gave his son ten envelopes and a thousand dollars, all in one dollar bills. He told his son, "Place the money in the envelopes in such a manner that no matter what number of dollars I ask for, you can give me one or more of the envelopes, containing the exact amount I asked for without having to open any of the envelopes. If you can do this, you will keep the R1000." When the father asked for a sum of money, the son was able to give him envelopes containing the exact amount of money asked for. How did the son distribute the money among the ten envelopes?
The Houston Rockets and Dallas Mavericks are playing in a professional basketball game. The Rockets have five players on the court. The Mavericks have eight players on the court. Professional basketball rules explicitly state that only five players are allowed on the court for each team. Where do the three extra players come from?
Now this is a problem for programmers. I won't give away the answer, though. (I've also seen "guess the number you're thinking of based on which cards the number's on" magic tricks very similar to this.) . . . . . A-Train's making me sad.
Hey, that's not what I was thinking you meant, but my way works too. Cut into 4 pieces, then down the middle /\ /\ /\ /\ Cut those four slices above right down the middle with one big slicer. You have eight.
