2. Let me introduce some interesting logical reasoning questions

Logical reasoning questions. What are they doing? Four people A, B, C, and D staying in the same room in a hotel are listening to a set of pop music. One of them is doing a manicure, one is writing a letter, one is lying on the bed, and the other is reading a book. .

1. A is not manicuring or reading a book; 2.

B is not lying on the bed or doing his nails; 3. If A is not lying in bed, then D is not doing his nails; 4.

C is neither reading nor manicuring; 5. D is neither reading nor lying on the bed.

What are they doing? Solution 1: Use the elimination method to solve 1, 2, 4, and 5. It is known that neither A nor B is trimming nails, nor is C. Therefore, the person trimming nails should be D; but this contradicts the conclusion of 3. Therefore, the premise of 3 is definitely not true, that is, A should be lying on the bed; in 4, C is neither reading nor manicuring his nails. According to the previous analysis, C cannot be lying on the bed, so C is writing a letter; and B is Reading a book. Solution 2: We can draw a 4*4 matrix, and then eliminate A B C D Manicure - - - + Write a letter - - + - Lie in bed + - - - Read a book - + - - Note: Only one can be taken from each row and column , once determined, the same column needs to be crossed out. We use "-" to indicate that someone's corresponding item has been crossed out, and "+" to indicate that someone is doing this.

①According to 1, 2, 4, and 5 in the question, we can cross out the corresponding items in the above matrix and express them with "-". (It can be seen that D is manicuring and B is reading a book) ②The solution to the question is A ≠ "lying in bed", then D ≠ "manicuring"; then the inverse proposition is: if D = "manicuring", then A = "Lying in bed".

(It can be seen from ① that A should be "lying in bed", so put a "+" in the corresponding item of "lying in bed") ③Now observe the matrix situation obtained in ①② and examine A and B , C, and D vertically, but in the row corresponding to the item "Writing a letter", you can only mark "+" at the corresponding C, that is, C is writing a letter. At this point, the matrix is ??completed.

We can draw judgments from this table. This is actually a logical reasoning question.

According to the above method, please think about the following question: There are six people of different nationalities, their names are A, B, C, D, E and F; their nationalities are American, German respectively. , Britain, France, Russia and Italy (the order of names is not necessarily consistent with the order of nationality) It is now known: (1) A and the American are doctors; (2) E and the Russian are teachers; (3) C and the German are Technician; (4) B and F have been soldiers, but the German has never been a soldier; (5) The Frenchman is older than A, and the Italian is older than C; (6) B and the Americans are arriving next week Going on a trip to England, C and the French are going to Switzerland for vacation next week. Please determine which country A, B, C, D, E and F are from respectively? Hint: You can list it as follows: A B C D E F United States - - - Russia - - - Germany - - - - English France - - - Italy - Answer: C.

British; A. Italian; B.

Russian; E. French; F.

American D. German.

4. Interesting Questions and Answers

(1) Very simple question 30 yuan - 25 yuan = 5 yuan. 3 people actually handed over 8.3 (3 cycles) yuan = 25 yuan to the waiter They took 2 yuan + 3 people each got 1 yuan + 25 yuan = 30 yuan. 3 people, 1 person took 10 yuan, 30 yuan, the boss refunded 5 yuan. The 5 yuan went to the waiter. At this time, the 3 people actually took it out, each person is 8.33 The recycling yuan waiter returned 3 yuan. At this time, each person actually took out 9.33 recycling yuan 9.3 Then it becomes (0.7+0.3)*10/2. Of course, it will cost half the money, so if you want to sell them separately, you have to raise the price (3) 3-2=1 meter on the first day and 1 meter on the second day. 1+3-2=2 meters. The third day 2+3-2=3 meters. The fourth day 3+3-2=4 meters. The fifth day 4+3=7 meters during the day. I can’t fall down so four and a half days (4 ) Buy 10 of the 15 pieces and finish eating, then exchange for 3 more peaches and there will be one hu left. After eating, you will always have four peaches. Exchange with the shopkeeper for two more peaches. After eating, just return the two peaches to him. So there are a total of ***15 (5) group numbers: A: 1234 B: 5678 C: 9, 10, 11, 12 Let the different balls be x for the first time AvsB 1. Equal weight, then x is at C.

Then take 123 vs 9, 10, 11 (1) with equal weight, then x = 12. Then 1vs12 will tell the importance.

(2) 123>9,10,11. Then 9vs10, when the weight is equal, x=11 or x=light ball. (3) 123<9,10,11. Similarly 9vs10, equal weight x=11 or x=heavy ball.

2. When A>B, divide 123456789 into three groups, 123,456,789. When the second statement is 456vs789 456=789, then x=123 and it is a heavy ball.

In 1vs2, if x 456>789 is obtained, it will be 4 heavy or 78 light. If 7vs8 has x 456<789, then 56 is lighter.

5vs6 vested x3, A

456vs789 When 456=789, 123 light, 1vs2 vested x. 456>789, 56 heavy, 5vs6 vested x. 456<789, 4 light or 78 heavy. 7vs8 vested x.(6) Of course the first time is to walk 200 kilometers.

Go back and forth 3 times and put down 2,000 sticks. The second time I walked to 553+1/3 kilometers, I put down 334 sticks and walked back with 333 sticks.

When we returned to 200 kilometers, the donkey had eaten these 333 pieces, but it had walked an extra 2/3 kilometers, but it did not need to be fed for less than 1 kilometer. This is when I took the remaining 1,000 sticks and ate 333 sticks when I walked to 553+1/3 kilometers. At the same time, I walked an extra 2/3 kilometers. At this time, I walked 1/6 kilometers further and came back 1/ 6 kilometers, make up 1 kilometer, eat 1 stick.

Then take the 334 sticks that you put down last time to make up the total of 1,000 sticks. Finally, I took these 1,000 radishes and walked out from 533+1/3 kilometers. The remaining distance is 466+2/3 kilometers, but I only need to eat 466 radishes. If the donkey dares to ask for more radishes, he will kill them. donkey.

The donkey won’t care about walking an extra 2/3 kilometers. So there are 534 sticks left.

This question is actually about making an integer game, and the focus is on this "integer thinking obsessive-compulsive disorder". (This sentence is wrong. The donkey still cares about that one. There are only 533 left in a ***. Alas.)

(7) 15621 A man gave 1 to the monkey and hid 3124 The second person gave the monkey 1 and hid 2499, leaving 9996; the third person gave the monkey 1 and hid 1999, leaving 7996; the fourth person gave 1 monkey hid 1599, leaving 6396; the fifth person gave 1 monkey, hid 1279, and left 5116; finally everyone divided it into 5 parts, each with 1023, 1 more, and gave The monkey (8) asked the little islander: If I ask you whether your left hand means yes, you will say yes, right? 1. The little islanders who tell the truth: 1. The left hand represents yes. The little islanders who speak the truth.

So the question is: If I ask you if your left hand means yes, you will say yes, right? The little islanders would say yes (I would say yes) and I would say yes. The left hand represents yes.

Truth-telling islanders. 2. If the left hand represents no.

The people who speak the truth are little islanders. Question: If I ask you if your left hand means yes, you will say yes, right? Little islanders would say no (I would say no), I would say no.

The left hand means no. True little islanders.

2. Lies to the little islanders: 3. The left hand represents yes. The little islanders who spoke are lies.

Question: If I ask you whether the left hand means yes, you will say yes, right? The little islander will say yes (because the false word little islander means I will say no), and I will say no. The left hand represents the little islanders who tell lies.

4. The left hand represents no, the speaking god is a lying islander. Question: If I ask you if your left hand means yes, you will say yes, right? The little islander will say no (because the lie is little islander, which means I will say yes), and I will say yes (contrary to the question, in fact the little islander will have nothing to say).

The islanders who have nothing to say are the islanders who lie. After determining whether what the small islander said was true or false, everything was easy to do. Ask the small islander whether the left hand represents it or not, ask the middle islander whether what the big islander said is true, and ask the big islander whether the treasure is on the mountain.

(9) The table in the room is a variable, the number of people = 315(11K+8)-1 K = 0,1,2,.

, infinite (K is a natural number) The solution to this problem is infinite EG: K=0 Number of people 2519 K=1 Number of people 5984 K=2 Number of people 9449 K=3 Number of people 12914... I have calculated this problem before, and it took me a long time to calculate it. It’s been verified! Don’t worry (10) The price of a spoon and fork is 1/21, the price of a knife is 1/28, the total price of a set is 1/21+1/28=1/12, so you can buy 12 sets for all the money. Although there are answers to this question on the Internet (11), I think the purpose of the questioner is to let you come up with solutions to the problem, so there should not be a standard answer.

I think: 1. If the river freezes in winter, then just run to it, and the police will continue to chase it and still not get rid of it. It is a waste of time to ask this question; 2. Use Swing the scarf over. This is a relatively standard answer given on the Internet. It also uses a bunch of formulas to prove the feasibility. This may be the original intention of the questioner, but the reality is, are there such high-quality scarves? Can a thief climb a 12-meter-tall tree? Can you find a suitable place to tie your scarf? Can you guarantee that you won’t get hurt while swinging there? The theory can be swung through. Does the thief have that kind of judgment? What if he is too nervous and cannot perform well and swam into the river? 3. The simplest and feasible thing. If you can swim across it, that’s the best. The 12-meter river is not far away and you won’t freeze to death even in the cold. The policeman has a lot of stuff on him and swimming has no advantage. He can get rid of it. This is my analysis, haha.

5. Interesting math questions and knowledge

1 Mr. Huang, Mr. Lan and Mr. Bai had lunch together. One is wearing a yellow tie, one is wearing a blue tie, and one is wearing a white tie.

"Have you noticed," said the gentleman in the blue tie, "that although the color of our ties happens to be the last names of all three of us, none of us has the same tie color as his own last name? ?"

"Ah! You are absolutely right!" Mr. Huang exclaimed. What color are the ties of these three gentlemen?

Mr. Huang is wearing a white tie.

Mr. Bai is wearing a blue tie.

Mr. Lan is wearing a yellow tie.

Mr. Huang cannot wear a yellow tie, because then the color of his tie would be the same as his last name. Nor could he wear a blue tie, since a tie of that color was already worn by the gentleman who asked him the question. So Mr. Huang must be wearing a white tie.

In this way, the remaining blue ties and yellow ties are tied by Mr. Bai and Mr. Blue respectively.

2 A mouse jumped into a circular lake with a radius of R to avoid being chased by a cat. The cat could not swim and could only pursue it along the lake shore, and always tried to get itself closest to the mouse ( That is, the cat always tries to position itself at the point closest to the mouse.) Assume that the maximum speed of the cat on land is 4 times the maximum speed of the mouse swimming in the lake. Can the mouse escape from the cat's pursuit? (If the cat is not at the position where the mouse landed when the mouse landed, the mouse is considered to have escaped the cat's pursuit)

Take the center of the lake as the center and R/4 as the radius to make a circle. If the mouse follows this circle Swimming, then the mouse in the water and the cat on the shore have the same angular velocity. If the radius of the mouse's swimming is slightly less than R/4, set to R', it will have a greater angular velocity than the cat. If the mouse swims long enough, It can be 180 degrees ahead of the cat, that is, the mouse is slightly less than R' to the left of the origin, and the cat is at R to the right of the origin. So now the mouse has to swim R-R', and the cat has to run 3.14*R

< p> As long as

4*(R-R')R'

The mouse can escape from the cat. In fact, this is completely possible.

p>

Solve equation (1) to get

R'>0.215R

It intersects with R'<0.25R, so the mouse can escape

3. A person used a counterfeit 50 yuan bill to buy a 20 yuan item. The boss had no money at the time, so he borrowed 50 yuan from a neighbor and paid 30 yuan to the customer, and then returned 50 yuan to the neighbor. I asked the boss how much he lost?

Actual loss: 30 yuan + the cost of the item

Adding the opportunity cost: 30 yuan + the highest possible price for the item

4 110 meters long A team moves at a speed of 1.5 meters per second. One player walks from the end of the team to the front at a speed of 4 meters per second. Then immediately returns to the end of the team at the original speed. Ask the team member from leaving the end of the team to returning to the end of the team. How many meters did the team travel? Try to change the above question into a question about finding the length of the team, and give the answer.

Taking the queue as the reference system, the speed of the team members walking from the end of the team to the front is 4-1.5=3.5m/s, It takes 4+1.5=5.5m/s from the beginning of the team to the end of the team

The time it takes for the players to leave the end of the team and return to the end of the team is t=110/3.5+110/5.5

< p> Using the ground as the reference system, the team's forward distance = 1.5*t=77.14m

Change to find the team length:

It is known that the team has moved forward s within this time, and Knowing the speed of the team relative to the ground can determine the time it takes the team to move forward. Taking the team as the reference system, the forward and return speeds of the team members are known. According to the two speed ratios, the time ratio can be known (because the forward and return displacements are the same), so the forward and return times can be obtained, and then the queue can be calculated. length.
