You're not full of questions.

The Germans raise fish This problem is analyzed a lot on the Internet, and it is very complicated to look at it slowly, and I have also done this problem myself, and the key is that the green house is on the left side of the white house, and this sentence should be understood according to the green house and the white house, rather than the house between them, and first of all, Norwegians can only live in green, white, and yellow houses, according to 4, Norwegians can only live in yellow houses, and then you can know that Norwegians smoke dunhill cigarettes, and the people in the second blue house raise horses, and then analyze 4, The green house can only be the third and fourth houses, first assuming that it is the third house, i.e. the middle house, but it conflicts with 5, so it can only be the fourth house, so the following result is obtained: Nationality Norway United Kingdom Color Yellow Blue Red Green White Drink Milk Coffee Pet Horse Cigarette dunhill Proceeds to the analysis, assuming that the owner of the blue house smokes bluemaster and drinks beer, because only the blue and white houses have not yet identified cigarettes and drinks Then it is learned from 3 that Norwegians drink water Nationality Norway Great Britain Color Yellow Blue Red Green White Drink Water Beer Milk Coffee Tea Pet Horse Cigarette dunhill bluemaster According to 15, it is known that Norwegians cannot drink water, so it is necessary to overturn the assumption that the owner of the blue house drank beer in front of him, then it is certain that the people of the white house drink beer and smoke bluemaster Nationality Norway United Kingdom Color Yellow Blue Red Green White Drink Milk Coffee Beer Pet Horse Cigarette dunhill bluemaster Then we can know from the table that Norwegians must drink water, The owner of the blue house is Danish and drinks tea (since 3), smokes blends Nationality Norway Denmark United Kingdom Color Yellow Blue Red Green White Drink Water Tea Milk Coffee Beer Pet Horse Cigarette dunhill blends bluemaster Then according to 13, the Green House is German and smokes prince, because the cigarette brand is still two people are not determined, and 13 of them give the answer Nationality Norway Denmark United Kingdom Germany Color Yellow Blue Red Green White Drink Water Tea Milk Coffee Beer Pet Horse Cigarette Dunhill Blends Prince Bluemaster Then needless to say, the people in the white house are Swedes, who have dogs, the British smoke pallmall, raise birds, and then according to 10, I know that Norwegians have cats, and finally at a glance, it is the Germans who raise fish! Nationality: Norway, Denmark, United Kingdom, Germany, Sweden, Color: Yellow, Blue, Red, Green, White, Drink, Water, Tea, Milk, Coffee, Beer, Pet, Cat, Horse, Bird, Fish, Dog, Cigarette, Dunhill Blends, Pallmall, Prince Bluemaster

Is this problem gone??

As far as I know, he has already been solved, and your question is not detailed enough ......

Einstein at the beginning of the 20th century did not come up with this problem, it is said that 98% of the world's people do not come out.

Problem: On a street, there are 5 houses, sprayed with 5 colors. There is no house with 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 to the left of the white house.

5.The owner of the green house drinks coffee.

6.People who smoke palmall cigarettes raise 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 bleeds cigarettes lives next door to the person who has a cat.

11.The horse breeder lives next door to the man 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 a bleed cigarette has a neighbor who drinks water.

Is this it??

The Germans raise fish, this is logical reasoning, and it is not difficult.

Norwegians live in the first house, drink water, raise pigs, smoke dunhill cigarettes, live in yellow houses. Danes live in a second house, drink tea, raise horses, smoke blends cigarettes, and live in a blue house. The British live in a third house, drink milk, raise birds, smoke pall mall cigarettes, and live in a red house.

Germans live in a fourth house, drink coffee, raise fish, smoke princely cigarettes, live in a green house. Swedes live in a fifth house, drink beer, have dogs, smoke blue master cigarettes, and live in white houses.

Let's say you originally had 50 dollars, buy the first one.

One, two, three, and four things cost a, b, c, and d, and at the end there is 0 left, then 50 = a+b+c+d.

Remaining after buying the first item: 50-a;

Remaining after buying the second item: 50-a-b;

Remaining after buying the third item: 50-a-b-c;

Remaining after buying the fourth item: 0; So the sum of the remaining money is: 150-3a-2b-c.

Since a, b, and c are indefinite numbers, the sum of the remaining money has an infinite number of outcomes. It means that the sum of the remaining money is related to the amount of money spent each time, and is not equal to the original amount of money.

There is exactly a difference of 1 in the question, which is purely a coincidence of numbers

The sum of the balances is meaningless, for example: 1 yuan for buying something: 49 remaining

Buy things for 1 yuan, and the remaining 48

Then it is the Germans who raise fish!
