The last question is very difficult. People who need to solve problems are super sensitive to numbers. The average person should not study too much. ) I borrowed the 12 table tennis question for this question, but the answer is more interesting. There are 1 1 fuwa and 1 fuwa. Fuwa eats cakes at the same speed, but Fuwa is different. How many cakes did it take to find this Fuwa?
(Hint: In order to avoid unnecessary problems, let me clarify that the eating speed difference between Fuwa and Beiwa is less than 1% for the same cake size. It is difficult for the naked eye to tell the speed of eating, but you can accurately tell which cake to eat first, which cake to eat after or eat at the same time, and you can also order the doll to start eating and stop eating. Without a watch, you can of course break the cake in half, but without a balance, you can't guarantee that the two halves are completely equal, only approximately equal. Answer 5: Cake is made for experts, and answer 4: Cake is made for experts. How to cut watermelon into 4 pieces and leave 10 skin after eating? (This question is reposted. Although Zodiac Labyrinth Studio doesn't like reposting, I feel that the original author's answer to this question is a bit superficial. In fact, this question is much more interesting than the original author imagined.
Different understandings can have different answers:
1. No matter how you cut it, the watermelon keeps a whole (the original title is easy to understand and suitable for primary school students. )
2. Divide into two pieces across the board, and you can't cut them together (please consider this situation, which is relatively difficult).
3. You can spell it, or you can spell it after eating (at this time, add another question, how many pieces of skin can you cut with 4 knives at most? )
Straight knife, of course, not crescent knife. Zodiac Labyrinth Studio hopes to recruit more talents with high IQ, so there is another problem. This question is inspired by the "Three Buddhas", but it is difficult. Don't be depressed if you can't solve it. After all, it is not easy to join the world's top studios.
Legend has it that there is an island of Ruozhi in the distant East China Sea. Three brothers are island owners. They are all fools. The fool is a toad with a mouth and can play the harmonica. The second fool is a crooked neck. He is good at playing the violin. The third fool has six fingers. He plays the piano very well. All three people are stupid to varying degrees, and the big fool is the stupidest. The questions asked of him are always answered incorrectly. It is better to be stupid, sometimes right and sometimes wrong; Three fools are better. I studied abroad and went to college for several years. The previous person answered the question correctly, so can he. A wrong answer by the previous person means a wrong answer.
A fan who has admired the IQ of the three island owners for a long time came to Ruozhi Island to try to distinguish who is the big fool, who is the second fool and who is the third fool. I want to ask you how to use the least number of questions and how to ask them to ensure that they can be identified. Of course, every question is answered by one of them, only yes orno. In order to avoid confusion, you also wear three labels of "A Dai", "Idiot" and "Idiot" with you, and put them on their heads as soon as you land. By the way, the first question asked three silly questions, and the three silly answers must be wrong.
There are too many traps in this problem, and everyone who solves it will be recognized as a fool. In fact, this is a question designed by the author to make fun of people. Because each trap is clever, it becomes an open question. When the intelligence problem reaches this state, the real master no longer cares about the right or wrong answer, but revels in the endless aftertaste of the trap. If there is a 100-foot mountain on the island of Chicago, there are many trees on the mountain, and one of them has many walnuts. It is said that eating it will make you smarter. Of course, you are salivating. But only the second fool knows the place, but he sometimes tells the truth and sometimes lies. Only the third fool knows whether the second fool is telling the truth or lies, but the third fool only tells the truth when the previous one tells the truth and lies when the previous one tells lies. If you ask him first, he is not sure. The third fool kept lying, and he knew whether the third fool was telling the truth.
Now suppose you have met three fools, how can you ask which tree grows on the mountain or at the foot of the mountain with the least problems? A purely logical question does not require a sharp turn of thinking with an open mind. There are three people: big fool, two fools and three fools. The big fool tells lies, the second fool tells the truth, and the third fool tells the truth. There are three peaches. Fake peaches turn true and false into liars, real peaches turn true and false into telling the truth, and liars become true and false. Inverting peaches makes people use no to indicate yes, and use yes to indicate no; Suppose three people each ate a peach; Ask how to distinguish who is who and who has eaten what peaches with the least number of yes or no questions. (Note: Not everyone tells the truth after eating)
