Ask for dogmatic IQ questions and describe the reasoning process

Filip is a college student, Eppel is a fighter, and Jake is a singer. Reasoning: B and C indicate that Jack and Eppel are not college students, because their age does not match, then only Filly is a college student, B shows that Filip is younger than Jack, because Filip is a college student, so through A it is explained that the warrior is Eppur, because Jack is much older than the warrior, and it is ruled out that Jack is a warrior.

The only Jack left is a singer.

Knowing that Filly is not a soldier from condition A Knowing that Jack and Eppel are not college students from condition BC Knowing that Filly is a college student Looking at condition B Feely is smaller than Jack And condition A says that Filly is bigger than a warrior So Jack is a singer Finally, we know that April is a soldier.

Filly is a college student, Ep is a warrior, and Jack is a singer, because first look at 1,2 guesses that Filly and Jack may be warriors and college students, respectively. And because of 3, so Ep is not a college student, then Philly, Jack may be a warrior, a college student, because of the big. Smaller than Jack, Filly is smaller than Warrior, so Filly is a college student.

In the analysis, it was concluded that Eppel was a warrior and Jack was a singer.

Jack is a singer, Filly is a college student, and Ep is a soldier.

Filly is a college student, Eppel is a fighter, and Jack is a singer.

Filly is not a fighter, Jack is not a college student, and Ep is not a college student.

So, Filly is a college student, Jack is older than Filly, Eppel is a warrior, and Jack is a singer.

Because it is known that B and C are college students who are Filly.

Because A, B, Eppel is a warrior.

Dejack is a singer.

I had a terrible language organization and didn't know how to say it, but what I came to it was.

Eppel is a college student, Jack is a warrior, and Filly is a singer.

If that's not clear, you can ask me, but tell me in detail, I don't know how to organize my language.

There are 3 sharpshooters, 100 shots, 3 people duel, each gun has 1 bullet, now the 1st line comes, and then, the 2nd and the last 3, they can do anything every time, of course, they can't rob other people's things, everyone wants to live as long as possible, and now they are standing on the 3 vertices of a waiting triangle, and ask the 1st what to do if he wants to win? No. 1 throws the gun to, between No. 1 and No. 3, according to everyone who wants to live as long as possible, No. 2 wants to hit No. 3, No. 1 picks up the gun, kills.

Light bulb: Imagine yourself in a room with three electrical switches. In the adjoining room there are three light bulbs (or rather lamps placed on ordinary tables) - they are not lit. Each switch controls a table lamp.

You can't see from one room to another. If you can only enter a room with the lights on once, how do you know which switch with which light? Your task is to determine all three switches (i.e. what bulbs are connected to switches 1, 2 and 3).

Answer: Turn the first light bulb on for a few minutes. It's going to get hot slowly, right?

Then you just need to ... Turn it off, turn on the other one, go into the room, feel which light is warm (the one that was turned on first), and the others can be easily distinguished...

Is it that the old man is holding the child, and the child raises a knife to kill people?

Reason: "Some witnesses said that ** is six feet tall", "there is a dark shadow moving in the corner", "the wound looks like the knife is cut from top to bottom, but the depth is not deep".

Reasoning: The old man is holding the child, "a child who looks like he is only 10 years old" raises a knife to kill, why do you say that, this child may be an adult, but he is suffering from dwarfism, "a dark shadow is moving", but two people came out. The child hid his face and cried bitterly, could it be that he didn't want to see his mature face, and the old man trembled, just because he was holding the dwarf, moving quickly, killing the family, and losing his strength?

The wound is cut from top to bottom, but the depth is not deep", because the old man is holding a dwarf and has an advantage in height, so the knife edge is cut from top to bottom. The reason for the lack of depth was that the dwarf was off the ground and had no way to borrow power.

**Yes Uncle, as for why, because the whole article is about three people, Catch Fast, Uncle, and Child;

I generally take the hypothetical approach.

Let's assume that the first sentence A says is right and the second sentence is wrong, and then we can see that the first sentence that B said is wrong The second sentence is right and the second sentence is wrong, so it is inconsistent with the original topic, so the initial assumption is not valid, that is, in fact, the second sentence said by A is correct and the first sentence is wrong, so it can be obtained that D is the third and A is not the second

The second sentence that B says is wrong The first sentence is right: [A is the first] The second sentence that C says is wrong, and the first sentence is correct is [C second].

Then B is the fourth.

To sum up: A first, C second, D third, B fourth.

Hope it helps.

Men can foresee not.

The current age, but how many years a person's life is, that is, the age at the time of death, let the woman say that she will be 51 years old in 5 minutes, then it means that she will die within 5 minutes, but the car will take 15 minutes to get to the next stop, combined with the fact that the other two people also died this year, so it is certain that the car will have a car accident during this journey, and all people will die, so the man will be blue and frightened!

That person could see someone's age at death and hear "Yes, but 51 years in five minutes!" The lady replied with a smile. The man knew that the express train was going to crash in five minutes, and no one was spared.

The answer is: September 1.

1.Xiao Ming said: "If I don't know, Xiao Qiang definitely doesn't know."

The subtext of this sentence is actually: "I should have guessed correctly, if I guessed wrong, Xiaoqiang definitely didn't know". But Xiao Ming is still not sure whether he guessed correctly or not, and Xiao Qiang needs to confirm it.

What value does m take to make Xiao Ming say that? Obviously, 6 and 12 are not advisable, if M is 6 or 12, N may be 2 or 7 - Xiaoqiang can know Mr. Zhang's birthday with a number of 2 or 7. m can only be 3 or 9, and n can only be taken in .

If m is 3, n can take three values, and the result is "If Xiao Ming doesn't know, Xiao Qiang may know (2 4, 3 8), or he may not know (3 5)." In this case, Xiao Ming's statement that "if I don't know, Xiao Qiang definitely doesn't know" is not in line with the facts, and Xiao Ming is not enough to say so confidently.

If m is 9, then Ming knows that n can only be 1 or 5. At this time, Xiao Ming's guess is n=1, and whether n is 1 or not, Xiao Ming is not sure, if n is not 1 but 5, then Xiao Ming said "If I don't know, Xiao Qiang definitely doesn't know". At this point, in fact, Xiao Ming already knows, and there are only two situations, just waiting for Xiao Qiang to confirm whether n is 5.

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

Xiaoqiang said, "I didn't know about it originally", verifying that n is indeed not 2 or 7; At the same time, Xiaoqiang also knew that "M is not 6 or 12, M only has 3 and 9 to be preferable". If n is 5, then Xiaoqiang should say "I didn't know it originally, but I still don't know it now". According to the inference of the first section, n = 1, so Xiaoqiang can say "I didn't know it at first, but now I know".

3.Xiao Ming said: "Then I know too".

Xiao Ming is waiting for Xiao Qiang's words, no matter how Xiao Qiang answers, Xiao Ming will know the correct answer. If Xiao Qiang says "I still don't know", then Xiao Ming can still know that "only n=5 will make Xiao Qiang at a loss", so the answer is September 5; If Xiaoqiang says "I know", then it must be September 1.

In fact, from beginning to end, Xiao Ming understood, he only needed Xiao Qiang to say Juhua to verify his guess, for Xiao Ming, it was a multiple-choice question of either A or B. Therefore, according to the story development clue of the topic itself, Xiao Ming's third sentence can be omitted, but many people use this condition when deriving - that is a bit like doing a math problem.

Known: Mr. P knows the value of this card, Mr. Q knows the suit of this card Mr. P: I don't know this card. Eliminate the J of spades 8 2 7 3 Grass Flower K 6, leaving hearts A Q 4 spades 4 Grass Flower Q 5 4 diamond A 5
