The latest answers to Einstein s super questions

When they climbed out of the chimney, one was clean, and the other was covered with soot! ~

This question should not be a logical one! Although I am too different from Einstein! But I think Einstein is misleading about this issue!

How can there be a correct answer to a wrong question? I guess Einstein wanted to tell us! When we have a problem!

Consider the reasonableness of the question itself! As for what kind of question this question belongs to! I'm sorry, I'm not a good learner!

I won't do it here! ~

Einstein's logic.

One day, Albert Einstein asked his students, "There are two workers who are repairing old chimneys, and when they climb out of the chimneys, one is clean, and the other is covered with soot, who of them will take a bath?" ”

One student said, "Of course the soot-covered worker will go to the shower!" ”

Einstein shook his head and said, "Really? Please notice that the clean worker saw another man with a face covered in soot and thought it was dirty to crawl out of the chimney, and the other saw that the other was clean and did not think so. I'll ask you now, who's going to take a bath? ”

Another student seemed to be enlightened and excited to discover the answer: "Oh! I know!

When a clean worker sees a dirty worker, he thinks he must be dirty, but when a dirty worker sees a clean worker, he thinks he is not dirty! So it must have been the clean worker who ran to take a shower! ”

Einstein looked at the other students, all of whom seemed to agree with the answer.

Albert Einstein smiled and said slowly, "This answer is also wrong." How can two people crawl out of an old chimney at the same time, one is clean and the other dirty? This is called logic. ”

Problem description: Albert Einstein came up with this question at the beginning of the 20th century, and it is said that 98% of the world's people cannot answer it.

On one street, there are 5 houses, sprayed with 5 colors. Each room is inhabited by people of different nationalities. Everyone drinks different drinks, smokes different brands of cigarettes, and has different pets.

The question is: who raises fish?

2. Swedes have dogs.

3. Danes drink tea.

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

5. The owner of the green house drinks coffee.

6. People who smoke palmall cigarettes raise traces of birds.

7. The owner of the yellow house smokes a dunhill cigarette.

8. People who live in the middle house drink milk.

9. Norwegians live in the first room.

10. The person who smokes blends cigarettes lives next door to the person who owns a cat.

11. The horse breeder lives next door to the person who smokes dunhill cigarettes.

12. People who smoke bluemaster drink beer.

13. Germans smoke prince cigarettes.

14. Norwegians live next door to the blue house.

15. The person who smokes blends cigarettes has a neighbor who drinks water.

Analysis: There are many people who know the results, but they all know what they are, and they don't know why.

It should be hard, and I don't want to be one of the 2%.

But I really am which 98%.

Please landlord, give advice, I am very grateful. Yuzhou Bu.

Scientist Albert Einstein did this question:

A long staircase, if you take 2 steps per step, then there is 1 step left at the end; If each step spans 3 steps, then there are 2 orders left at the end; If each step spans 5 steps, there are 4 steps left at the end; If each step crosses 6 steps, there are 5 steps left at the end; Only when you take 7 steps per step will you be exactly finished, and there will be no one step left. Q: How many steps are there at least on this ladder?

Solution: In other words, this topic is:

A long ladder, its order is divided by 2 by 1, by 3 by 2, by 5 by 4, by 6 by 5 by 5, by 7 divisible by 7, find at least how many steps?

In this way, the topic is compressed and simplified, which can be used to facilitate thinking. There are a total of 5 conditions in the question, which can be solved in two steps.

In the first step, according to the four conditions of "the order is divided by 2 by the remainder 1, by 3 by the remainder 2, by 5 by the remainder 4, by 6 by the remainder 5", it can be seen that as long as 1 is added to the order, it is a multiple of the four numbers.

The smallest common multiple is: 30

So 29 (30 1) is the least natural number that satisfies these four conditions.

The second step, the fifth condition, is "divisible by 7", and 29 obviously does not meet this condition. How can this condition be met? Using 29 as the base number, add the least common multiple of 30 consecutively to obtain:

29＋30=59 59＋30=89 89＋30=119……The resulting sum, after calculation, if it can be divided by 7, then the answer is found. Here 119 7 = 17 is already in line with the goal, so there is no need to add any more. 119 is the minimum number of steps.

Answer: This is an divisibility question.

As you can see, this number plus 1 is divisible.

And this number is divisible by 7.

Add 1 divisible number and 30 60 90 120 150....

Subtracting 1 is divisible by 7 to 120, minus 1 = 119, divisible by 7, so the smallest number is 119

Add one order first, and the least common multiple of the ladder that is divisible by is 30

So the number of steps is 30a-1

The number of steps is a multiple of 7.

So 7x = 30n-1, i.e. x = (30a-1) 7 and 30 7 = 4 and 2

Therefore, a n-3 can be satisfied.

That is, the number of steps is: 30*(7n-3)-1=210n-91Answer: There are 210n-91 steps in the ladder.

The minimum is 210-91=119 orders.

According to each step across 5 steps, the last remaining 4 steps can be obtained, the mantissa of this step is 4 or 9, by each step across 2 steps, the last remaining order can be obtained, the mantissa of this step is an odd number, it can be concluded that the mantissa of this step can only be 9, and according to the time of crossing 7 steps, it is just the end, from this can be obtained that the number of steps is a multiple of 7, and according to the mantissa is 9, so it can only be 7 * 7, or 7 * 17, or 7 * 27....After calculation, 7*17=119 is exactly the same, so the number of steps is 119

The number x is a multiple of 7 and x+1 is a common multiple of x+1=120

x=119There are 119 steps on this ladder.

1.The British live in the Red House.

2.Swedes have dogs.

3.Danes drink tea.

4.Germans smoke prince cigarettes.

5.Norwegians live in the first room.

6.Norwegians live next door to the blue house. The Blue House is the second one.

7.The green house is to the left of the white house; The Blue House is the second; The British live in the Red House. It is concluded that the Yellow House is the first; Norwegians live in yellow houses.

8.The owner of the yellow house smokes a dunhill cigarette. It was concluded that Norwegians smoke dunhill cigarettes.

9.The horse breeder lives next door to the man who smokes dunhill cigarettes. It was concluded that the owner of the blue house raised horses.

10.The Yellow House was the first; The Blue House is the second; The green house is on the left side of the white house; The owner of the green house drinks coffee; People who live in the middle house drink milk. It is concluded that the Red House is the third; The Green House is the fourth; The White House is the fifth.

The owner of the red house drinks milk.

11.The British live in red houses. The owner of the red house drinks milk. It was concluded that the British drank milk.

12.Danes drink tea. The British drink milk; The owner of the green house drinks coffee; Smokers of the Blue Master drink beer; Norwegians live in yellow houses; Norwegians smoke dunhill cigarettes; It was concluded that Norwegians drink mineral water.

13.The person who smokes blends cigarettes has a neighbor who drinks water; The Blue House is the second; It was concluded that the owner of the blue house smoked a mixed cigarette.

14.Danes drink tea. The British drink milk; Norwegians drink mineral water; The owner of the green house drinks coffee; Smokers of the Blue Master drink beer; Germans smoke prince cigarettes. It is concluded that Germans drink coffee and live in green houses; Swedes smoke Blue Master cigarettes and drink beer.

15.Norwegians live in yellow houses; The British live in the Red House. Germans live in green houses; The owner of the blue house raises horses; Swedes have dogs. It is concluded that the Danes live in blue houses; Swedes live in white houses.

16.The owner of the Blue House smokes a mixed cigarette; The Danes live in the Blue House. It is concluded that the Danes smoke mixed cigarettes.

17.Norwegians smoke dunhill cigarettes; Danes smoke mixed cigarettes; Germans smoke prince cigarettes. Swedes smoke Blue Master cigarettes. It is concluded that the British smoke Pall Mall cigarettes.

18.Brits smoke Pall Mall cigarettes; People who smoke Pall Mall cigarettes keep birds. It is concluded that the British raised birds.

19.People who smoke mixed cigarettes live next to cat owners; Danes smoke mixed cigarettes; The Danes live in the Blue House. The Blue House is the second; The British kept birds; The British live in the Red House. The Red House is the third. Came up with the first house owner with a cat. i.e. Norwegians have cats.

SO rooms 1-5 are: yellow, blue, red, green, white.

Yellow: Norway, punhill, cat, water.

Blue: Denmark, blnds, horses, tea.

Red; England, Pall Mall, Birds, Milk.

Green: German, prince, fish, coffee.

White: Swedish, blue master, dog, beer.

So it was the Germans who raised fish.

Remember to deduce the possibility in room 2 with the possibility that it may be Denmark or Germany, and finally deduce all the possibilities and then determine that 2 is Dan through the reverse deduction of the probability, and then it is all determined!

First house:

Norwegians, the house is yellow, drinks water, smokes dunhill, has a cat.

Second house:

Danes, the house is blue, they drink tea, smoke blends, they have horses.

The third house:

British, the house is red, they drink milk, they smoke a pall mall, they have birds.

The fourth house:

Germans, the house is green, they drink coffee, they smoke prince, they raise fish.

Fifth house:

Swedes, the house is white, drinks beer, smokes a blue master, and has a dog.

It was the Germans who raised the fish.

It's all wrong! The correct answer should be Danish people who raise fish!

If there is no restriction on the green house next to the white house, then the answer will be that the Germans raise fish or the Danes raise fish.

No, because it doesn't say that the fish is the one left.

Dane! I'm exhausted.
