The peasant needs to transport a wolf, a goat and a cabbage across the river. But the boat is such that only a peasant can fit in it, and with him either one wolf, or one goat, or one cabbage. But if you leave a wolf with a goat, then the wolf will eat the goat, and if you leave a goat with cabbage, then the goat will eat the cabbage. How did the peasant transport his cargo?
Solution 1: It is clear that we have to start with a goat. The peasant, having transported the goat, returns and takes the wolf, which he transports to the other bank, where he leaves it, but he also takes the goat and takes it back to the first bank. Here he leaves her and transports the cabbage to the wolf. Then, returning, he transports the goat, and the crossing ends safely. Solution 2: First, the peasant again transports the goat. But the second one can take the cabbage, take it to the other bank, leave it there and return the goat to the first bank. Then transport the wolf to the other side, return for the goat and again take her to the other side.

At first glance, it may seem that a person will take the last pill in an hour and a half, because this is exactly three times for half an hour. In fact, he will take the last pill not in an hour and a half, but in an hour. The person immediately drinks the first tablet. Half an hour passes. He takes the second pill. Another half hour passes. He takes the third pill. Therefore, the person will take the last tablet an hour after the start of treatment.

261. In the dense Murom forest, ten springs of dead water gush out of the ground; they are numbered from No. 1 to No. 10.
Anyone can take dead water from the first nine springs, but source No. 10 is located in Koshchei’s cave, which no one except Koshchei himself can get into.
The taste and color of dead water is no different from ordinary water, however, if a person drinks from any source, he will die. Only one thing can save him: if he drinks poison from a source whose number is higher. For example, if he drinks from the seventh spring, then he must wash it down with poison No. 8, No. 9 or No. 10. If he drinks not the seventh poison, but the ninth, only poison No. 10 can help him. And if he immediately drinks the tenth poison, then nothing will help him.
Ivanushka the Fool challenged Koshchei to a duel. The conditions of the duel were as follows: everyone brings a mug with liquid and gives it to their opponent to drink. Koschey was delighted: “I will give poison No. 10, and Ivanushka the Fool will not be able to escape!” And I myself will drink the poison that Ivan the Fool brings me, I will drink it with my tenth and I will be saved!”
On the appointed day, both opponents met at the appointed place. They honestly exchanged mugs and drank what was in them. It turned out that Koschey died, but Ivanushka the Fool remained alive! How did this happen?
Ivanushka gave Kashchei plain water, and it turned out that Kashchei drank poison from the 10th spring. Before the duel, Ivanushka himself drank poison from any one source and it turned out that he washed down the poison with Kashcheev 10, and as a result this poison was neutralized..

263. How to divide five apples between five people in such a way that one apple remains in the basket? (Joke task)
One out of five people must pick up their apple along with the basket. The effect of this not very serious task is based on the ambiguity of the expression “the apple is left in the basket.” After all, it can be understood both in the sense that no one got it, and in the fact that it simply did not leave the place of its original stay, and these are completely different things. Add what is highlighted in yellow as a note to the same task, we have it.

According to the condition, the number of leaves doubles every day, and if on the 99th day the pond is half covered with leaves, then the next day the second half of the pond will be covered with lily leaves, i.e. The pond will be completely covered with them in 100 days.

268. The missionary was captured by savages, who put him in prison and said: “There are only two exits from here - one to freedom, the other to death; Two warriors will help you get out - one always tells the truth, the other always lies, but it is not known which of them is a liar and which is a truth-teller; You can only ask any of them one question.” What question do you need to ask to get free?
We must turn to any of the warriors with the following question: “If I ask you whether this exit leads to freedom, will you answer me “yes”?” With this formulation of the question, the warrior who lies all the time will be forced to tell the truth. Suppose you, showing him the exit to freedom, say: “If I ask you whether this exit leads to freedom, will you answer me “yes”?” In this case, the truth will be if he answers “no,” but he has to lie and therefore he is forced to say “yes.”

The girl fell silent, but when they got there, she realized that the driver was playing a joke on her. How did she guess?

272. A train leaves Moscow for Vladivostok every day. Also, every day a train leaves Vladivostok for Moscow. The move lasts 10 days. If you left Vladivostok for Moscow, how many trains going in the opposite direction will you encounter during your trip?
At first glance, it may seem that during the trip we will meet ten trains. But this is not so: we will meet not only those ten trains that left Moscow after our departure, but also those that were already on their way by the time of our departure. This means that we will meet not ten, but twenty trains.
Correct answer
273. There is a simple and cheap way to travel, which, surprisingly, no one uses. As you know, the Earth rotates around its axis, and quite quickly (in just 24 hours, each point on the Earth’s equator travels approximately 40,000 km - a path equal to the length of the equator). This means that instead of going somewhere by train or flying by plane, or sailing on a ship, we just need to rise high above the earth in a balloon or airship and stay there motionless for some time. During this time, the Earth will turn towards us with another part of its surface and we just need to descend to the right place. Is this reasoning correct? If not, what mistake was made in it?
This method of travel is, of course, unsuitable. The atmosphere, attracted by the Earth, rotates with it. And even if the atmosphere were stationary, then, having risen into it from the rotating Earth, we would continue the earth’s movement for some time by inertia. In addition, if the atmosphere were motionless, and the Earth continued to rotate in it (and quite quickly: see the problem statement), then in this case a huge hurricane would not cease to rage on Earth, which would make not only any travel impossible , but also human life itself.
Correct answer
274. Is it possible to boil water over an open flame in a paper box?
The question of the problem, at first glance, seems very strange, because if you hold the paper over the fire, it will definitely catch fire. But the fact is that the boiling point of water is much lower than the ignition temperature of paper. Since the heat of the flame is absorbed by the boiling water, the paper cannot reach the required temperature and therefore does not ignite. The paper just needs to be thick enough, otherwise the water will simply tear it and spill onto the flame. A cardboard box is quite suitable for boiling water. The same explanation underlies the phenomenon of fireproof paper tightly wound around a metal rod (or steel nail) and introduced into the flame of a candle. The heat of the fire will be absorbed by the rod, preventing the paper from heating to the desired temperature and igniting.
Correct answer
275. In one class, the students were divided into two groups. Some were always supposed to tell only the truth, while others only told lies. All students in the class wrote an essay on a free topic, which had to end with the phrase: “Everything written here is true” or “Everything written here is a lie.” There were 17 truth tellers and 18 liars in the class. How many essays did you get with a statement about the veracity of what was written?
All the truth-tellers truly claimed that everything they wrote was true, but all the liars falsely claimed that everything they wrote was true. Thus, all 35 essays contained a statement about the veracity of what was written.

278. A bottle with a cork costs 1 rub. 10 kopecks. A bottle is 1 ruble more expensive than a cork. How much does a bottle cost and how much does a cork cost?
At first glance, it may seem that a bottle costs 1 ruble, and a cork costs 10 kopecks, but then the bottle is 90 kopecks more expensive than a cork, and not 1 ruble, as is the case. In fact, a bottle costs 1 rub. 05 kopecks, and a cork costs 5 kopecks.
Correct answer
279. Katya lives on the fourth floor, and Olya lives on the second. Rising to the fourth floor, Katya climbs 60 steps. How many steps does Ole have to go up to get to the second floor?
At first glance, it may seem that Olya walks 30 steps - half as many as Katya, since she lives half as low as her. Actually this is not true. When Katya goes up to the fourth floor, she climbs 3 flights of stairs between floors. This means there are 20 steps between the two floors: 60: 3 = 20. Olya rises from the first floor to the second, therefore, she climbs 20 steps.
Correct answer
280. How can you pour exactly half of a mug, ladle, pan or any other dish of regular cylindrical shape, filled to the brim with water, without using any measuring instruments?
Any dish of regular cylindrical shape, when viewed from the side, is a rectangle. As you know, the diagonal of a rectangle divides it into two equal parts. In the same way, a cylinder is divided in half by an ellipse. Water must be poured from a cylindrical container filled with water until the surface of the water on one side reaches the corner of the container, where its bottom meets the wall, and on the other side the edge of the container through which it is poured. In this case, exactly half of the water will remain in the dish:
Correct answer
281. Three hens lay three eggs in three days. How many eggs will 12 hens lay in 12 days?
You can immediately answer that 12 hens will lay 12 eggs in 12 days. However, it is not. If three hens lay three eggs in three days, then one hen lays one egg in the same three days. Therefore, in 12 days she will lay: 12: 3 = 4 eggs. If there are 12 hens, then in 12 days they will lay: 12 · 4 = 48 eggs.

However, the seller did not lie. How is this possible? (The task is a joke.)
The parrot can indeed repeat every word it hears, but it is deaf and cannot hear a single word.
Correct answer
284. There is a candle and a kerosene lamp in the room. What will you light first when you enter this room in the evening?
Of course, a match, since without it it is impossible to light a candle or a kerosene lamp. The question of the problem is ambiguous, because it can be understood either as a choice between a candle and a kerosene lamp, or as a sequence in lighting something (first a match, then everything else from it).

286. Over time, man will definitely visit Mars. Sasha Ivanov is a person. Consequently, Sasha Ivanov will definitely visit Mars over time. Is this reasoning correct? If not, what mistake was made in it?
The reasoning is incorrect. It is not at all necessary that Sasha Ivanov will eventually visit Mars. The external correctness of this reasoning is created due to the use of one word (“man”) in two different senses: in the broad (abstract representative of humanity) and in the narrow (specific, given, this particular person).
Correct answer
287. It is often said that one must be born a composer, or an artist, or a writer, or a scientist. Is this true? Do you really have to be born a composer (artist, writer, scientist)? (The task is a joke.)
Of course, a composer, as well as an artist, writer or scientist, must be born, because if a person is not born, then he will not be able to compose music, draw pictures, write novels or make scientific discoveries. This joke problem is based on the ambiguity of the question: “Do you really have to be born?” This question can be taken literally: is it necessary to be born in order to engage in any type of activity; and this question can also be understood in a figurative sense: is the talent of a composer (artist, writer, scientist) innate, given by nature, or is it acquired during life through hard work.
Correct answer
288. In order to see, it is not at all necessary to have eyes. Without the right eye we see. We also see it without the left one. And since we have no other eyes besides the left and right eyes, it turns out that not a single eye is necessary for vision. Is this statement true? If not, what mistake was made in it?
The reasoning is, of course, incorrect. Its external correctness is based on the almost imperceptible exclusion of one more option, which also needed to be considered in this argument. This is an option when no eye can see. It was he who was missed: “We see without the right eye, without the left one too, which means that the eyes are not necessary for vision.” The correct statement should be: “Without the right eye we see, without the left we also see, but without the two together we do not see, which means we see either with one eye, or with the other, or with both eyes together, but we cannot see without eyes, which, thus essential for vision.”
Correct answer
289. The parrot lived less than 100 years and can only answer “yes” and “no” questions. How many questions should he be asked to find out his age?
At first glance, it may seem that you can ask a parrot up to 99 questions. In reality, you can get by with a much smaller number of questions. Let’s ask him this way: “Are you over 50 years old?” If he answers yes, then his age is from 51 to 99 years; if he answers “no,” then he is from 1 to 50 years old. The number of options for his age after the first question is halved. The next similar question: “Are you over (you can ask, less than) 25 years old?”, “Are you over (less than) 75 years old?” (depending on the answer to the first question) reduces the number of options by four times, etc. As a result, the parrot needs to ask only 7 questions.
Correct answer
290. One man who fell into captivity says the following: “My dungeon was in the upper part of the castle. After many days of effort, I managed to break out one of the bars in the narrow window. It was possible to crawl into the resulting hole, but the distance to the ground was too great to simply jump down. In the corner of the dungeon I found a rope forgotten by someone. However, it turned out to be too short to climb down. Then I remembered how one wise man lengthened a blanket that was too short for him by cutting off part of it from the bottom and sewing it on top. So I hastened to divide the rope in half and tie the two pieces together again. Then it became long enough, and I safely went down it.” How did the narrator manage to do this?
The narrator divided the rope not across, as most likely it might seem, but along it, making two ropes of the same length. When he tied the two pieces together, the rope became twice as long as it was at first.

The main goal of the course on entrepreneurship and innovation by Tina Seelig, a Stanford teacher and the author of the new product"Make yourself ", - show students that for any problem you need to look for a creative solution.
To do this, she offers her students several exercises that you can use.
Exercise 1. The best of the worst
The group is divided into small teams, each of which must come up with the best and worst idea to solve the problem. Once the teams are finished, they write down each of their ideas on a separate piece of paper, one with "BEST" written on it and "WORST" on the other. Then the sheets with the BEST ideas are demonstratively destroyed and each team receives a sheet of paper with the WORST ideas of the other team. After that, they are given the task of turning this idea into a great one.
Result
After taking a closer look at new ideas, participants usually realize that they are not so bad after all. For example, a group that got the idea to sell bikinis in Antarctica came up with the slogan “Bikini or Death.” Their new idea was to take people who wanted to get in shape on a trip to Antarctica. By the end of the arduous journey, they could fit into a smaller bikini.
The group, who needed to perfect the idea of cockroach sushi, came up with a proposal to open a restaurant called Cucaracha, serving a variety of exotic sushi made from unconventional yet nutritious ingredients, for an adventurous audience.
This exercise is a great opportunity to open your mind to problem solving. It shows that most ideas that may seem stupid at first often contain an interesting kernel. It helps challenge assumptions that ideas are inherently good or bad, and shows that with the right state of mind, you can find something valuable in any idea or situation.
Exercise 2. Upside down circus
Write down all the stereotypes about a traditional circus: big tent, animals, cheap tickets, barkers selling souvenirs, several simultaneous acts in the arena, loud and upbeat music, clowns, popcorn, strongmen, fire eaters, etc.
Next, imagine the antipode of each of the described characteristics. For example, the new list may include a low roof, no animals, expensive tickets, no barkers, sophisticated music, no clowns or popcorn.
Result
Once you've done the circus exercise, you'll find it much easier to think about changes in other industries: fast food restaurants, hotels, airlines, sports facilities, educational institutions, and even courts and municipalities.
When all circus shows in the 1980s were terribly predictable and derivative, with audience numbers steadily declining, the idea of Cirque du Soleil challenged every established idea of what a circus should look like.
Exercise 3. Taking out wallets
Participants are asked to take out their wallets. Then they pair up and tell each other about their wallets. They discuss what they love or hate about them, or talk about how they use them for shopping and document storage.
Result
Most people who use wallets are frustrated to some degree by the limitations of the item. Therefore, after completing the interview, each of the participants begins to create a new wallet design for their interlocutor, the “client”. The designer has only simple objects at his disposal: paper, adhesive tape, markers, scissors, paper clips, and the like. Customers love the new concepts and often say that if such a wallet were on sale, they would definitely buy it.
There are a ton of lessons to be learned from this exercise. Firstly, a wallet is a symbol of the fact that problems can be found everywhere, even in your own pocket.
Second, solving these problems may require only minor efforts. People are usually happy to tell you about their problems.
Thirdly, simple solutions can be found through simple experiments. They do not require a significant amount of work, resources or time. And even if you fail, your costs are minimal. And all you need is to just start over.
Exercise 4. Drive is more important than competition
In an entrepreneurial environment, drive is always more important than competition. In order to confirm this thesis, Tina Seelig has developed a special exercise.
Six teams receive five completed puzzles of 100 pieces each. Participants are given a minute to look at the finished pictures, after which the elements of all the puzzles are put together into one huge pile and mixed.
All the pieces are then distributed among the six teams. In addition, each team receives 20 poker chips, which can be used as currency. Teams must complete the puzzle in one hour.
Since the number of puzzles is smaller than the number of teams, participants must decide whether they will compete, cooperate, or combine both strategies to collect the required pieces.
Result
To achieve success, teams must work together. Since they know that the number of puzzles is less than the number of teams, at least one team must decide not to complete the puzzle, but to play some other role. Sometimes two or three teams merge. At times, a team may take on the role of a broker, exchanging pieces of the puzzle with other teams. Sometimes all the teams merged into one and worked together to solve the puzzle. The worst outcome occurs when all teams decide to compete with each other.
This exercise forces participants to understand that in environments with limited resources, motivating oneself and others to succeed is often a more productive strategy than pure competition. People who are able to tune in to this wavelength are able to more actively take on the skills and tools that others bring to the process, and also enjoy the successes of others.
