Q: The neighbor's question comes from Einstein. According to him, 98% of people can't do it.

There are five houses in a row, each with a different color. Five people of different nationalities live in these houses. Everyone feeds different animals, likes different drinks and smokes different cigars.

The Englishman lives in a red house.

Swedes keep dogs.

Danes drink tea.

The green house is on the left of the white house.

The owner of the green house likes to drink coffee.

People who smoke "Pomo" cigars keep birds.

The owner of the yellow house smokes "Dunshan" cigars.

People who live in the middle house drink milk.

Norwegians live in the first house.

Polish cigar smokers live with cat owners.

The owner of the horse lives next to the man who smokes Dunshan cigars.

People who smoke blue-collar cigars drink beer.

Germans smoke Prince cigars.

Norwegians live next to the blue house.

The Polish cigar smoker has a neighbor who drinks water. Who raises fish?

Are you one of those 2%?

Analysis process:

First of all, we can know that the Norwegian is in room 1 and the milk drinker is in room 3.

Norwegians live next to the blue house. 》

1 There is only one house next to the Norwegians, so the second house is blue.

The green house is on the left of the white house.

The owner of the green house likes to drink coffee.

This question can tell us that if 1 is green, then No.2 is white, but No.2 is blue.

If No.3 is green, it won't work, because people in the green room drink coffee and No.3 drinks milk.

So it only makes sense that the 4th is green and the 5th is white (attention! You can modify all the answers here. Not that green is next to white. This is just Einstein's trap. There are actually two answers. Let's assume it's next door.

The Englishman lives in a red house. Now there are only 1 and 3 without colors. How do you know who is red? It's simple. It depends on nationality. 1 is Norwegian, not British. Number three.

The house is red and the owner is English. 1 is the yellow room.

1 2 3 4 5

Norway England

Red, blue, yellow, green and white

milk coffee

There is an obvious message that the owner of the Huang family smokes "Dunshan" brand cigars. 》

1 is a red house, so he draws a mountain, and then there is a movie like Norwegian lives next to the blue house. "The problem is that there are people who smoke" Dunshan "brand cigars next door to the owner of the horse."

This is also very simple, that is, the red room 1, and he has only one neighbor, No.2.

So No.2 keeps a horse.

1 2 3 4 5

Norway England

Red, blue, yellow, green and white

milk coffee

horse

Dunshan

Then there is the difficulty that Einstein said "98% people can't do it"

Find out what information you can know first.

Danes drink tea.

The Polish cigar smoker has a neighbor who drinks water.

People who smoke blue-collar cigars drink beer.

All three questions have moisture. Let's look at them first. What house do people drink from?

The Dane may be Room 2 4 5, so he can rule out Room 4, because he drinks tea, so Denmark is one of Room 2 5.

No.65438 +0 can be ruled out if he doesn't smoke a pole (except that he doesn't smoke a pole but may drink water). Neighbor No.5 (No.4) drinks coffee (No.4), and drinking milk on No.3 can be ruled out, so the person who drinks water may be one of the rooms in 125.

1 can rule out drinking milk on the 3rd and coffee on the 4th, so the beer drinker may be the 25th.

Einstein riddle answer

Known as the most difficult problem in the world! Einstein solved the mystery at the beginning of the 20th century. He said that 98% of the people in the world couldn't answer it.

1. On a street, there are five houses painted in five colors.

People of different nationalities live in each room.

Everyone drinks different drinks, smokes different brands of cigarettes and keeps different pets.

The question is: Who raises fish?

Tip:

1, the British live in a red house.

15. People who smoke mixed cigarettes have a neighbor who drinks water.

Einstein solved the mystery at the beginning of the 20th century. He said that 98% of the people in the world couldn't answer it.

Reasoning process:

First, let's position ourselves. From left to right, 12345 is arranged according to the location of the house.

The Norwegian lives in room 1, on the far left. The British live in a red house, while the Norwegians live next to the blue house. The colors of Norwegian houses can only be green, yellow and white. The green house is on the left of the white house, and the Norwegians live next to the blue house. Norwegians can only live in yellow houses and smoke Dunhill cigarettes. The second room is a blue house. Again, the green house is on the left of the white house, and the green house can only be in the third or fourth room. If the green house is in the third room (that is, the middle room), the people living in the middle house drink milk, and the owner of the green house drinks milk, which contradicts the conditions for the owner of the green house to drink coffee. Wrong guess, the green house is in the fourth room, and its owner is drinking coffee. Further on, the third room is a red house, where the British live and drink milk. The fifth house is a white house. Danes drink tea, green house owners drink coffee, British people drink milk, people who smoke blue masters drink beer, and Norwegians can only drink water. People who smoke blended cigarettes have a neighbor who drinks water, and people who smoke blended cigarettes can only live in a second house.

Now let's tidy up. 1 The room is a yellow house. It lives in Norway, smokes Dunhill cigarettes and drinks water. The second house is a blue house. The owner keeps horses and smokes cigarettes. The third room is a red house, where English people live and drink milk. The green house is in the fourth room, and its owner drinks coffee. The fifth house is a white house. People who smoke blue masters drink beer; People who smoke blue masters and drink beer can only live in the fifth hospital. Germans smoke prince cigarettes, and Germans can only live in the fourth house. People who smoke Beiermei cigarettes keep birds, and only the British smoke Beiermei cigarettes to keep birds. The person who transfers cigarettes lives next door to the cat owner, and the person who transfers cigarettes can only be Norwegian or British, the cat owner is Norwegian or British, the British keep birds, and the cat owner is Norwegian.

Now let's tidy it up again. 1 The room is a yellow house. It lives in Norway, smokes Dunhill cigarettes, drinks water and keeps cats. The second house is a blue house. The owner keeps horses and smokes cigarettes. The third room is a red house, where English people live, drink milk, smoke Pall Mall cigarettes and keep birds. The fourth house is a green house, living in Germany, smoking prince cigarettes and drinking coffee. The fifth is the white house, where the owner smokes blue master and drinks beer. ∵ Swedes have dogs, and ∵ 1, the owners of rooms 2 and 3 don't have dogs, the owners of the fourth room are Germans, and the fifth room lives in Sweden and has dogs. 1, 3, 4 and 5 The owners of the houses are Norwegian, British, German and Swedish respectively. The owner of the second family is Danish and is drinking tea.

Finally, sort out the results. 1 The house is yellow. It lives in Norway, smokes Dunhill cigarettes, drinks water and keeps cats. The second house is a blue house, living in Denmark, smoking mixed ...>& gt.

Where did deciphering those super-classic puzzles come from in the first place?

The English live in a red house. 3. Spaniards have dogs. People who live in green houses drink coffee. 5. Ukrainians drink tea The green house is on the right of the milky white house. 7. Take the last romantic paragraph to raise snails. 8. Mint smokers live in a yellow house. 9. People who live in the middle house drink milk. 10. Norwegians live in the first house. 1 1. People who smoke chesterfield live next door to people who keep foxes. 12. People who smoke mint cigarettes live with people who keep horses. 13. People who smoke lottery tickets drink orange juice. 14. Japanese cigarettes are supreme. 15. The Norwegian lives next door to the blue house. So, who drinks water? Who keeps zebras? The earliest known source of this puzzle is the international edition of Life magazine (1962 17 February). On March 25th, 1963, the magazine published the answer and the list of hundreds of solvers around the world. There are countless variants of this puzzle, one of which is which country fish farming is more extensive on the Internet. People are afraid of famous pigs and strong pigs. This complicated puzzle is inexplicably attributed to Einstein, the smartest brain in the 20th century. This question was made up by Einstein when he was young and widely circulated, so this puzzle is often called Einstein's riddle. But some people say that the author is actually lewis carroll. Well, let's leave these groupies alone, because there is no evidence that the author is any of them now. Besides, the cigarette brand in the puzzle did not appear when Einstein was a child. Pirate Puzzle This is a popular puzzle, which contains popular elements such as piracy, money and democracy. The story goes like this: There are five rational pirates A, B, C, D and E, and they got 100 gold coins, and they want to share them. There are different levels in the pirate world. The ranking of these five pirates is as follows: A B C D E. The system of sharing stolen goods is also very democratic: first, the pirates with the highest level put forward the distribution plan, and then all pirates (including the proponents) voted to decide whether to accept it or not. If more than half of the people agree, the proposal will be passed, otherwise the sponsor will be thrown overboard, and the pirate with the second highest level will continue to propose, and so on. The factors considered by pirates are: one is to survive, the other is to get the most money; If they get the same money anyway, they are more willing to kill others. For A, the best scheme is as follows: A gets 98, B gets 0, C gets 1, D gets 0, and E gets 1. The answer is almost beyond everyone's expectation. Generally, we will give the other four pirates gold coins to save our lives through the proposal, but the answer tells us that greed is better. The mystery of pirates first appeared in the May issue of Scientific American, 1999. This article entitled "The Puzzlement of Pirates" was written by ian stewart, a British mathematician. He analyzed the problem in detail and expanded the number of pirates to n, and got a very interesting conclusion. He heard about this difficult problem from Stephen M. Moderow. It is speculated that this puzzle has been circulating for at least 10 years. This is a classic puzzle in every way. This interesting question will be mentioned in any game theory course. Where is the dollar? Three travelers checked into a hotel, and the boss accepted their 30 yuan at the price of 10 yuan per person. Later, the boss decided to give them some discounts and gave the waiter 5 yuan to return to the passengers. It is obvious that the boss can't do math and gave a number that can't be divisible by 3. The clever waiter secretly hid 2 yuan himself, and then returned 1 yuan to every passenger. Now every customer has given a discount of 1 yuan, so everyone has given it to 9 yuan, one to 27 yuan, and 2 yuan and the waiter are 29 yuan. But at first they gave the boss, 30 yuan. Where's the other dollar? Almost everyone will be fooled after reading it, and then watch it ... >>

Einstein solved a difficult problem at the beginning of the 20th century. ) Is it true that 98% of people can't answer? What if the answer comes out?

It means you are more logical and smarter.

Einstein's 1 1 abnormal myth

Einstein put forward this riddle in the early 20th century. He said that 98% of the people in the world couldn't answer it.

Intelligence test;

1. On a street, there are five houses painted in five colors.

People of different nationalities live in each room.

Everyone drinks different drinks, smokes different brands of cigarettes and keeps different pets.

The question is: Who raises fish?

Tip:

1, the British live in a red house.

2. Swedes have dogs

3. Danes drink tea

The green house is on the left of the white house.

5. The owner of the greenhouse drinks coffee

6. People who smoke keep birds.

7. The owner of the yellow house smokes Dunhill cigarettes.

People who live in the middle house drink milk.

9. The Norwegian lives in the first room.

10. People who smoke mixed cigarettes live next door to the cat owner.

1 1. Horse owners live next door to smokers on Dunhill Road.

12. People who smoke BlueMaster drink beer.

13, Germans smoke prince cigarettes.

14. The Norwegian lives next door to the blue house.

15. People who smoke mixed cigarettes have a neighbor who drinks water.

The fifth five-year plan problem (the legend is that Einstein wrote the topic)

The first room: yellow, Norwegian, keeps foxes, smokes Kuhl cigarettes and likes drinking water.

The second room: Ukrainian with blue nails, raising horses, smoking chesterfield cigarettes and drinking tea.

The third room: red, English, keeps snails, smokes Winston cigarettes and likes to drink milk.

The fourth room: ivory white, Spanish, keeps a dog, smokes Luchy Strike cigarettes and likes to drink orange juice.

The fifth room: green, Japanese, raising zebras, smoking parliaments, and enjoying coffee.

Einstein solved the mystery at the beginning of the 20th century.

The first house, the yellow house, is Norwegian, drinking water, keeping cats and smoking Dunhill cigarettes.

The second house, the blue house, is Danish, drinking tea, raising horses and smoking mixed cigarettes.

The third house, the red house, is English, drinking milk, raising birds and smoking small cigarettes.

The fourth, green house, German, drinking coffee, raising fish and smoking prince cigarettes.

The fifth house, the White House, is Swedish, drinking beer, keeping dogs and smoking BLUEMASTER cigarettes.

This answer is correct.

The green house is on the left of the white house, and the owner of the green house drinks coffee, so it can be determined that the location of the green house is the fourth house. Just rule out that it is impossible to build a house at 1235 (the reason is quite simple, I believe everyone wants it, so don't bother). The positions that can be determined are as follows.

The first house is Norwegian.

The second house, the blue house.

The third house drinks milk.

The fourth house, the green house, drinks coffee.

The fifth house, the White House

If an Englishman lives in a red house again, it can be determined that the Englishman lives in the third house and the yellow house is the first. The owner of the yellow house smoked Dunhill cigarettes, and the results were as follows.

The first house, the yellow house, the Norwegian smoked Dunhill cigarettes.

The second house, the blue house, raises horses.

The third house, the red house, British people drink milk.

The fourth house, the green house, drinks coffee.

The fifth house, the White House

The next step is the key. If Danes drink tea, then Danes can only live in 2 or 5, provided that 12. People who smoke blue master cigarettes drink beer and may appear in the No.2 or No.5 hospital. Suppose the Danes who drink tea live in Room 5, then 5 cups are tea, 2 cups are beer, cigarettes and Master Lan, and 1 cup is water. Under the condition of 15, it is obviously contradictory that a neighbor who smokes mixed cigarettes drinks water, so two cigarettes are mixed. So Danes can only live in a second house and five cigarettes.

The first house is a yellow house. Norwegians drink water and smoke Dunhill cigarettes.

The second house, the blue house, Danes drink tea, keep horses and smoke.

The third house, the red house, British people drink milk.

The fourth house, the green house, drinks coffee.

The fifth house, the White House, drinks beer and smokes blue cigarettes.

The next thing is simple, the condition is 13. Germans smoke prince cigarettes, so Germans can only live in room 4, on condition that 2. Swedes live in room 5 and have dogs. Condition 6: The pail mall was taken by an Englishman in Room 3, who keeps birds. It is concluded from the condition of 10 that the first house has cats. Finally, the answer came out. Germans raise fish. ^_^

Einstein put forward this riddle in the early 20th century. He said that 98% of the people in the world can't answer who raises fish. Are you one of those 2%?

You should be reminded: 1, English people live in red houses 2, Swedes keep dogs 3, Danes drink tea 4, green houses are on the left of white houses 5, owners of green houses drink coffee 6, people who smoke Pall Mall cigarettes keep birds 7, owners of yellow houses smoke Dunhill cigarettes 8, people who live in middle houses drink milk 9, and Norwegians live in the first room 65438+. Blends smokers live next door to cat owners 1 1, horse owners live next door to Dunhill smokers 12, blue owners smoke beer 13, Germans smoke prince cigarettes 14, and Norwegians live next door to blue houses.

A bit like Sudoku, my method is to create a table (figure 1), fill in the blanks according to the prompts, and finally reason. If one of the given prompts is obviously used, delete one. (All * * * numbers in the table are related prompt numbers, the same below).

Figure 1

Firstly, determine the most direct condition, namely 9, 14, 8;

At this time, 4 and 5 are judged jointly. Because B is a blue house, A can't be green. Because C drinks milk, C is not green. Only D is green, E is white, and D drinks coffee.

At this time, it can be determined that 1, the Englishman living in the red house is C;

Then there are only seven tips related to the color of the house; Then 1 1 is also determined. Here, the color of the house has been determined, but we are just beginning to understand the fish farmers. (Figure 2)

Figure ii

Next, because the brand of cigarettes is too complicated, I will abbreviate it:

Pall Mall=pm

Mixed =bs

Blue master =bm

Prince = public relations

At this point, observing the rest of the tips and our watches, we know that two Swedes with dogs can only stay in D or E; 3 Danes who drink tea can only be in B or E; People who smoke bm can only smoke B or E, suggesting that most of them are disorderly cigarettes. Ethnic groups and drinks have been determined in two ways, while animals and cigarettes have only been determined in one way, so we start reasoning from drinks and branches, which is feasible as long as it does not conflict with other tips in the process.

Branch 1: Starting from 12, suppose that people who smoke bm drink beer in B and Danes drink tea in E, then 15 cannot be established.

Branch 2: Starting from 12, suppose that people who smoke bm drink beer in E, and then three Danes drink tea in B. At this time, people who smoke bs in 10 and 15 must be in B, because only A is a neighbor who drinks water, but it doesn't matter who owns a cat in A and C, see 13. Germans can only stay in D, so Swedes keep dogs in E, so only one smoking spot is pm6, and he keeps birds. Looking back at this time 13, only A keeps cats, and finally it is concluded that D is a German who lives in a green house, drinks coffee and smokes pr cigarettes. (Figure 3)

Figure 3

Other possible situations (starting with nationality) can be tried again by yourself.

Friendly reminder: smoking is harmful to health!
