Find interesting logic questions, very interesting logic questions

A lied in weeks 1, 2, and 3, B also lied in weeks 4, 5, and 6, and the rest of the time they told the truth.

One day a man asked, "What day of the week is today?" ”

Result A said"Yesterday I lied", b said"Yesterday I lied", so what day of the week is today?

There are three spirits, A, B, and C, one of whom only tells the truth, and the other only tells lies. There is also a random decision when to tell the truth and when to tell a lie. You can ask the three elves three yes/no questions, and your task is to find out who is telling the truth, who is telling the lie, and who is answering randomly from their answers.

The hard part of this puzzle is that these spirits use "da" or "ja", but you don't know what they mean, only that one of the characters means "right" and the other word means "wrong". What are those three questions you should ask?

A man wants to go to a castle, and there are two forks in the road to the castle, and only one leads to the castle, and there is a lion in each way, and one lion tells the truth and the other lion tells a lie, and this person can only ask one lion and can only ask one question, how can he ask to know the way to the castle.

Maria is wearing socks and Sun Ting is barefoot, and Umeko Tanaka is wearing stockings.

Assuming that A is right that Sun Ting is wearing stockings, then it is not satisfied that C said that Sun Ting was barefoot and Mary was wearing stockings, so the family said that Sun Ting was wearing stockings is wrong. Since half of each person is correct, it follows that A says that Mary is wearing stockings, and it follows that C is wrong when Mary is wearing stockings, and Sun Ting is right when she is barefoot, and B is wrong when she says that Sun Ting is wearing stockings, and Umeko Tanaka is correct when she wears stockings. In the end, Maria was wearing socks, Sun Ting was barefoot, and Umeko Tanaka was wearing stockings.

Maria wears socks, Sachiko Tanaka wears stockings, and Sun Ting is barefoot.

Which village in Xingcun Township has a meat pigeon landing king.

It's all 72.

Analysis of 144 from the third person: the number of the first two people must be the same, so that if the first or second person and the third person add up to the second person, then the third person must be equal to 0, and 0 is not a positive integer, so only the number of the third person is the sum of the numbers of the first two people, that is, 144.

One is 36 and one is 108, I think so.

Answer: I think I've seen this question before.

Follow the conventional method.

8 + 9 - 10 + 11 = 2 yuan.

If you have an investment mind, you can earn 3 yuan by selling the chicken directly to D.

Some people think it's a loss of one dollar.

Suppose A has 10 yuan, spends 8 yuan to buy chicken, and there is 2 yuan, and he sells it for 9 yuan, and he has 11 yuan, and he spends 10 yuan to buy it, and he has 1 yuan, and finally he sells it for 11 yuan, and he still has 12 yuan on his body. Earned $2.

Don't say anything, he can sell it directly to D and earn 3 yuan, and now he has earned 2 yuan and lost 1 yuan.

He didn't do that on the street this time, and only earned 2 yuan.

I made two dollars, the first time I bought 8 and sold 9 and earned one yuan, and the second time I bought 10 and sold 11 and made 1 yuan, for a total of two yuan.

It cost 8+10 to buy chickens, and 9+11 to sell chickens, column: (9+11) (8+10)=2

After thinking about it rationally and prudently, I came to this conclusion: First of all, Xiao Li shot Xiao Huang, but because Xiao Li's success rate was only 30, so the probability of this shot was not very large, assuming that Xiao Li did not hit, then after Xiao Li hit, it should be shot by Xiao Huang, of course Xiao Huang will choose to shoot 100% Xiao Lin, 50 hit rate, first of all, let's say Xiao Lin is hit, then the first to eliminate is of course this, the unlucky guy who doesn't even have a chance to shoot, but after Xiao Huang shoots, Xiao Lin who should shoot has been eliminated, so of course, it will be Xiao Li's turn to shoot, Xiao Li's 30 hit, the probability of hitting Xiao Huang in the second shot is not very high, then in the second time suppose Xiao Li did not hit, in this turn Xiao Huang shot, Xiao Huang after successfully killing the biggest competitor, his heart will definitely decompress, he will be very relaxed, then his 50 hit, the probability of another successful hit is not very large, so it will be Xiao Li's turn to shoot again, in a highly tense and concentrated state, Xiao Li missed two shots, and the third shot hit with 30 hits, the probability of hitting Xiao Huang will be greatly improved, then the probability of hitting this shot is as high as 90, and Xiao Li will have a great chance of surviving in the end.

First of all, Xiao Huang is the biggest threat to Xiao Lin, so Xiao Lin will definitely fight Xiao Huang. In the same way, Xiao Huang will definitely fight Xiao Lin. Then Xiao Li's optimal strategy to shoot first is not to shoot anyone.

This can ensure that after entering the heads-up, Xiao Li shoots first. Then in the first round, Xiao Huang has a 50% chance of killing Xiao Lin, otherwise Xiao Huang will be killed by Xiao Lin. In the second round, Xiao Li will have a 30% chance of killing his opponent, otherwise, if the opponent is Xiao Lin, Xiao Li will be killed directly, and if the opponent is Xiao Huang, Xiao Li will have a 50% chance of entering the third round.

On the whole, Xiao Li has a better chance of surviving, followed by Xiao Lin, and Xiao Huang is the worst.
