An interesting logic question, an interesting logical reasoning question

The answer should be.

1. Xiao Ming said: If I don't know, Xiao Qiang definitely doesn't know that June and December can be excluded from this sentence.

Xiao Ming said that Xiao Qiang did not know when he knew m, which means that this m corresponds to all n and does not have those numbers that are unique among all n. And June has 7 days and December has 2 days, both are unique, excluding June and December.

If the above is not easy to understand, please assume that you are Xiao Ming and m=6, do you dare to say this? Don't dare, because if n is 7, Xiaoqiang will know the result immediately. The same is true for excluding m=12.

2. The remaining dates are:

March 4, March 5, March 8.

September 1 September 5.

Xiaoqiang said: I didn't know it at first, but now I know.

This means that the n value is unique among the top 5 dates, excluding n = 5, and the remaining dates are.

March 4 March 8.

September 1 Third, Xiao Ming said: Oh, then I also know.

Xiao Ming knew that M got the result from the above three dates, indicating that M is unique among the above three dates.

And so the result was:

I also think that June and December can be excluded from the beginning

I'm going to come up with a different answer than what you offered, and I'm going to think about it slowly

I'm from the original first floor, and I think September 1st is the right answer

That's right, I see what they said, it was also launched on March 4th.

From "Mr. P: I don't know this card", it can be seen that although he knows the value of the card, he still can't know what card it is, that is, this point has at least two suits, so it can only be one of A and Q; From "Mr. Q: I know you don't know this card.

It can be seen that Q knows that the value of this suit card can only include A and Q, that is, the suit of the card can only be hearts and diamonds; From "Mr. P: Now I know the card. "You know, the number of points that P sees is unique among the three suits of hearts and diamonds, that is, it can't be an A, it can only be a Q.

If the card is an ace, Mr. P still can't tell. From "Mr. Q: I got it, too.

It can be seen that the suit can only be a square. If it is a heart, after Mr. Q excludes A, he still can't tell if it's a Q or a 4. To sum up, this card is a 5 of diamonds.

Let's start with the inappropriateness of the question. The inappropriateness of the moderator's question was that the two options were not complementary. That is, there is a situation where neither a sorcerer nor a master of national studies.

A reasonable question should include all the situations, for example, some netizens call you a master of Chinese studies, and some netizens are not so artificial, do you think you are a master?

Of all the options, only d is complementary, and what is inevitable and what is likely to be avoided is complementary. a, let's not talk about it, it's not the right number at all. b. Development sacrifices the environment, does not develop and does not destroy the environment, it is not complementary, and there is a situation where both development and environmental damage are not destroyed.

c, people are selfish, people are not selfish, and they are not complementary, there are situations where some people are selfish and some are not selfish. e, it is inevitable to win the championship, it is impossible to win the championship and it is not complementary, there is a situation where it is possible to win the championship.

In general, only d is complementary, and such a question is more appropriate.

I will give you a puzzle logical reasoning problem, come and try to solve the puzzle.

First of all, logically speaking, the truth and falsity of the original proposition and the inverse proposition are the same.

So (if Qin Chuan passes the exam, then Qian Hua, Sun Xu and Shen Nan must also pass) The inverse negative proposition is.

If someone fails Qian Hua, Sun Xu and Shen Nan, then Qin Chuan fails the exam) is also a true proposition.

Therefore, if Sun Xu fails and meets the condition of "Qian Hua, Sun Xu and Shen Nan are not qualified", then "Qinchuan failed the exam" must be established.

And "Qin Chuan failed the exam" was established, then "Qin Chuan and Shen Nan will not both pass the exam" was established.

Therefore, from "Sun Xu's grades did not pass", it can be deduced that "Qin Chuan and Shen Nan will not both pass the test", so E is right.

a, (If Qin Chuan does not pass the exam, then at least one of the three people, Qian, Sun, and Shen, will not pass.) ) is a negative proposition of the original proposition, and there is no connection between the two. So wrong.

b, b is part of a, and a is wrong, then a part of a b is also wrong.

c, c is the inverse of a, and if a is wrong, then c is also wrong.

d, in the question, Shen Nan's results have nothing to do with Qian Hua and Sun Xu, but only with Qin Chuan, so it is wrong.

May my answer be helpful to you! If you have any questions, please ask and be willing to answer them. If you understand and solve your problem, please adopt it as a satisfactory answer in time! If you have other questions, please take this question and send another click to ask me for help, it is not easy to answer the question, please understand, thank you.

That's right! The correct answer is only e.

Judging from the proposition, there is only one definite inference: if any of the three people Qian Hua, Sun Xu and Shen Nan failed, then Qin Chuan definitely did not pass. Is that right?

There's no problem with this, right? There can be no second definite inference. Then it depends on which of the following 5 options fits this inference, or directly conforms to the proposition itself.

Obviously, only E can be launched - Sun Xu didn't pass, so Qin Chuan definitely didn't pass. Qin Chuan has definitely failed. Then it is impossible for him and anyone else to "pass".

So E is right. The other 4 clearly do not conform to the proposition and inference.

Question 1: Are you normal? It is humans who answer yes, and it is ghosts who answer no. Because a normal person will say yes when he tells the truth, and a sick person will say yes if he tells a lie. A normal ghost will say no if he tells a lie, and a sick ghost will say no if he tells the truth.

After asking question one, after knowing whether the other party is a human or a ghost.

1) For example, the other party is a person.

or (2) the other party is a ghost.

I'm smart, I'm a traveler

1 You're sick, aren't you? The answer "no" is a human being, and the answer "yes" is a ghost.

2 From 1 it can be found that p is a man or a ghost Then you ask: Are you a ghost? If P is sick, answer "Yes", if you don't, answer "No" If P is a ghost, you can also ask this question.

Question 1: Are you a ghost?

Question 2: Are you sick?
