Logic tasks for preschoolers
Preschool development, Education and upbringing
One of the popular sites social networks moms love to post different kind puzzles that are not only too tough for their children, but also for the parents themselves. Sometimes they are even funny, but they call them logical. Recently, indeed, teachers have been paying increased attention to the development of logic, and note that this process must begin long before the start of school life.
Logic tasks for preschoolers
What are logic puzzles for?
Logical thinking is a kind of symbiosis of mental, mental and cognitive skills that are formed in a baby from birth. The main task of parents and educators is to teach the child to use them so that he sees the relationship between them and learns to draw conclusions.
A child is able to make independent logical conclusions by the age of five. Of course, with the condition that both parents and educators paid due attention to the development of logic.
Later, at school, and throughout life, such a child will quickly and correctly reflect any processes, navigate the system of new knowledge and cope with new activities.
What can be logical tasks for preschoolers
It is not at all necessary to look for logical tasks for preschoolers in special manuals or books on development. They are at every turn! It is enough for parents to carefully look around and see that logic surrounds us everywhere.
For example, you came with the baby to the rink. Try telling him a turnaround phrase: “It's summer now, and that's why we came to the skating rink. When winter comes, we will go to the river together.
Follow the reaction and ask to restore this situation correctly.
Most often, you can use the already existing knowledge of the child in order to draw a new conclusion. For example, a five-year-old son perfectly counts to 10. Put 5 apples in front of him and ask: “How many apples do you need to report here so that there are 10 of them?” Children really like such tasks, they happily begin to think, wrinkling their foreheads.
Another very entertaining way to develop logic in preschoolers: looking at pictures where there are extra elements. For example, in the group of thematic cards "Outerwear" put a picture with sandals.
Children are very fond of listening to sounds, so you can turn on the audio recording of the voices of different animals, and between them - the singing of a bird. Usually kids take it as a game.
Examples of logic tasks
If you do not have enough imagination or time to invent yourself logic puzzles use our resources. Recommended for children under 5 years of age.
- Task 1. Kolya's apple is green and sour, and Zhenya's is big and sweet. What is the same in these apples?
- Task 2. Tanya and Marina played with dolls. Tanina's name was Masha, and Marinin's was Klava. What was the name of Tanya's doll, if her name was not Klava?
- Problem 3. Vanya and Sanya were drawing together. Vanya drew a cat, and Sanya drew a bowl of milk for him. What did Vanya draw if Sanya did not draw a cat?
- Problem 4. Petya, Borya and Slavik lived in the same house with four entrances: Petya - in the 3rd entrance, Borya - in the 2nd, Slavik - in the 4th. In what entrance did their new friend Vasya live, if he did not live, neither I, one of the guys?
Logic tasks with answers
Logic tasks with answers are more like riddles, however, tricky ones. But children love them just because the answer can be the most unexpected.
Give them the opportunity to think, reflect, maybe even give the wrong version. But thanks to this, the preschooler's logical thinking, his attentiveness and confidence are trained.
Be sure to encourage your son or daughter for the correct answers, and if an error occurs, it’s okay, explain how to reason correctly. Then the time spent together will be joyful for both you and the child.

Logic for preschoolers.
This topic is relevant, because. thinking presupposes a logical structure of thought, without constructing thoughts logically correctly it is impossible to draw conclusions. It is at preschool age that elements of logical thinking begin to form in children.
Based on the figurative and is the highest stage in the development of children's thinking. Reaching this stage is a long and difficult process, as full development logical thinking requires not only high activity mental activity, but also generalized knowledge about the general and essential features of objects and phenomena of reality, which are enshrined in words.
One should not wait until the child is 14 years old and reaches the stage of formal-logical operations, when his thinking acquires the characteristic mental activity adults. The development of logical thinking should begin in preschool childhood.
But why logic little child, preschooler? The fact is that at each age stage, a certain “floor” is created, as it were, on which mental functions are formed that are important for the transition to the next stage.
Thus, the skills acquired in preschool period, will serve as the foundation for gaining knowledge and developing abilities at an older age - at school. And the most important among these skills is the skill of logical thinking, the ability to "act in the mind."
A child who has not mastered the methods of logical thinking will find it more difficult to study - solving problems, doing exercises will require a lot of time and effort. As a result, the health of the child may suffer. Weaken, and even completely fade away interest in learning.
Having mastered logical operations, the child will become more attentive, learn to think clearly and clearly, be able to concentrate on the essence of the problem at the right time, convince others that he is right. Learning will become easier, which means that both the learning process and school life itself will bring joy and satisfaction.
The logic of thinking involves active mental activity based on direct interest. Based on the logic of action, decisions are made mental tasks, which are implemented by means of the game in game actions.
In the work on the development of logical thinking, such methods are used as finding a solution through ingenuity, resourcefulness, initiative, as well as a variety of entertaining material - these are games, tasks, puzzles. All this gives the basis for the ability to analyze, systematize, find the right solutions, patterns that require the use of mathematical methods and conclusions.
The effectiveness of the development of logical thinking of preschoolers increases if visual models act as teaching aids, acquaintance with which should begin already in the younger and middle groups.
To do this, a good developmental environment should be created in the group: didactic games, visual and didactic aids, hand-made games, tables. In the book corner, place not only books for reading and viewing, but also various entertaining material for the development of logical thinking - crosswords, puzzles, rebuses and magazines.
Children with great desire solve logical exercises, identify patterns and continue them. They are persistently looking for solutions that lead to a result.
When entertaining task is available to the child, a positive attitude towards it develops, which stimulates mental activity. Children are interested in the ultimate goal: to add, find desired shape, transform - it captivates them.
You need to start your work with the simplest: children's ability to compare objects, find how they are similar and how they differ, find an extra or missing object. In work, use tasks and games “What has changed?”, “What is missing?”, “Find two identical objects”. Based on this, to form the ability of children to identify patterns in the arrangement of figures in diagrams, tables “What object to draw?”, “Put a figure instead of a question?”.
Pay attention to the development of logical thinking in children. To form the ability to single out and compare parts and the whole in objects and actions. Use the games "Make a picture", "Magic square".
Suggest didactic exercises“Which ball is missing”, “What house should be built?”. With interest, the children performed practical tasks to find the pattern "Plant a flower", "Continue the row".
Playing logic games is useful at any age. Therefore, you should not set any specific age limits for the participants in the game.
Here are a few of them:
For understanding: "Pathfinder". Traces of animals and people are drawn, guess whose traces.
On the development of artistic and figurative thinking: "Clouds" what do clouds floating across the sky look like? "Shadow" - determine from the shadow what object it is from.
Games for intuition: "Drawings". Draw a figure.
"Rhymes". Finish the poem. Use the works of Korney Chukovsky, Samuil Marshak, Agniya Barto.
Games for the development of attention: “What is superfluous?”, “Find the differences”
These logic games can be played as kindergarten. So at home with my parents.
Through didactic games, it is possible to form new knowledge, to acquaint them with methods of action. Didactic games included in the content of the lesson, as one of the means of implementing program tasks.
Most often, didactic games are used as an educational task in order to form new knowledge, consolidate program material. For example, through the didactic game "Merry Logic" to exercise children in the ability of visual examination and analysis of objects. Using various didactic games in working with children, I was convinced that when playing, children learn the program material better and correctly perform complex tasks.
Application didactic games increases efficiency pedagogical process, in addition, contribute to the development of memory, thinking in children, having a huge impact on mental development child. Teaching children in the process of playing, I strive to ensure that the joy of games turns into the joy of learning.
With the help of such tasks, a logical operation is worked out - NEGATION, which is performed with the help of "not". The logical link "not" is very important for the development of logical thinking and speech. The solution of such problems requires concentration of attention, develop memory and ingenuity.

AnswerThe problem says that Vasya is three years older than Koshkin. This indicates that his last name is not Koshkin. Therefore, Vasya Sobachkin, and Kolya Koshkin.
2. What is the last name of each of the girls? Olya and Katya have the surnames of Lisichkina and Zaitseva. What is the last name of each of the girls, if it is known that Katya and Zaitseva are classmates?
AnswerThe problem says that Katya and Zaitseva are classmates. So Katya is not Zaitseva, but Lisichkina. Then Olya - Zaitseva.
3. Three brothers - Petya, Seryozha and Dima - studied in different classes of the same school. Petya was no older than Dima, and Seryozha was no older than Petya. Name the oldest brother, the middle brother and the youngest.
Answer: Dima is the eldest, Petya is the middle one, Seryozha is the youngest.
4. Three friends studied in the same class: Seryozha, Tolya and Yura. They were all different sizes. Seryozha was not lower than Tolya, and Yura was not higher than Tolya.
Which of them was shorter than all, average in height and taller than all?
Answer: Yura is below everyone, Tolya is average, and Seryozha is above everyone.
5. 12 students from the same school live in the same house. This school has three first, three second and three third grades. Do you think that among the students living in this house there are at least two people who study with the same teacher.
Explain your answer.
In total, there are 3+3+3=9 classes in the school, and there are 12 students living in the house. Therefore, there will definitely be those who study in the same class.
6. When Anya, Sveta and Nina asked what marks they got for the test, the teacher answered:
Try to guess for yourself if I say that there are no bad grades in your class, but the three of you have different grades, and Anya has not 3, Nina has not 3 and not 5. What grade did each of these students receive?
Answer: Nina has a score of 4, Anya - 5, Sveta - 3.

Which of these guys should leave the house before everyone else, who a little later, and, finally, which of them meets the other two so that they can come to school at the same time?
Answer Volodya should leave before everyone else, then Tolya and, finally, Sasha.
8. There are 400 students in our school. How to prove that among the students there are at least two people who have the same date and month of birth without viewing documents, without interviewing students or their parents.
Answer: There are 365 days in a year, and there are 400 students in the school, that is, more than the number of days in a year. This means that there will definitely be students who have the same date and month of birth.
9. The envelope contains squares, circles and triangles cut out of paper - a total of 7 pieces. There are 3 times more squares than triangles. How many circles are in the envelope?
AnswerFirst, let's find out how many squares and triangles can be in the envelope separately. If there were 2 triangles, then 2*3=6 squares, and only 2+6=8, that is, more than 7. So the triangle was 1, and 1*3=3 squares. Together they were 1+3=4.
Now let's count how many circles are in the envelope: 7-4=3.
10. There are two varieties of sweets in the package. They take a few sweets at random. What is the smallest number of sweets you need to take so that there are at least two candies of the same variety among them?
Answer: If you take only two candies at random, then they can be of different varieties. If you take three sweets, then they cannot all be of different varieties, since there are only two varieties. Therefore, you need to take at least three sweets.
11. There are 34 students in the class. Prove that there are at least two students in this class whose last names begin with the same letter.
There are 33 letters in the alphabet. Since there are more students in the class than there are letters in the alphabet, there will definitely be several surnames in it that begin with the same letter.

How to teach a child math
In this article, we will talk more about how to prepare a child for learning mathematics.
You have a child, and you are beside yourself with surging happiness only from the realization that you have now become a happy mother and, finally, there will be someone to pass on your maternal love and knowledge. Not without reason, from time immemorial, all the leading philosophers have emphasized in every possible way that when parents want to raise their child in the image and likeness, hard or soft, they voluntarily or involuntarily want their baby to look like themselves. This process is called education.
It is not for nothing that people say that a kind person helps everyone, while a smart one helps only those in need. And if you want to see your child not only kind, but also smart, then you need to start the whole process of education from infancy. But where do you start?
You need to start small. From logic. In order for your child to believe in the existence of causal relationships, you must always and must fulfill your parental promises (for example, “if you behave, then we will definitely go to the zoo.”)
If your kid is already seriously interested in children's books, then it will be useful to add verbal logical puzzles and tasks with answers, like: “If this is so, then this is because ...” or “What will happen if I do the opposite?” “How can all this be explained?” The development of logic is helped by simple children's riddles, puzzles, rebuses. Make it a rule to have a mystery night at least once a week. Teach your child to make puzzles.
Your child is entering a stage when everything becomes extremely interesting for him, and you can and should play on his curiosity so that he can quickly learn and, most importantly, understand the world. And simple worldly logic will only be to his advantage.
To make it easier for your child to understand and understand all this, it will be useful to include in role-playing games some elements of ready-made conclusions, like: “Your dolls go to bed in the evening, because they get tired during the day. But my Volodya is also tired, and it’s time for him to go to bed too.”
You can also show such an example from the world of “Moydodyr” that if “the children do not wash and comb their hair, then the rest of the children in the kindergarten will not play with him.” Already in the process of growing up your child will be able to give much deeper concepts with logical overtones. Here you need to apply the main and basic principle - so that your child already begins to clearly understand that in this world there is always both a cause and an effect.
History of mathematics for children
The history of the development of mathematics is not only the history of the development of mathematical ideas, concepts and trends, but it is also the history of the relationship between mathematics and human activity, the socio-economic conditions of different eras. The formation and development of mathematics as a science, the emergence of its new sections is closely related to the development of society's needs for measurements, control, especially in the fields of agriculture, industry and taxation.
The first areas of application of mathematics were associated with contemplation of the stars and agriculture. The study of the starry sky made it possible to build trade sea routes, caravan roads to new areas and dramatically increase the effect of trade between states.
The exchange of goods led to the exchange of cultural values, to the development of tolerance as a phenomenon underlying the peaceful coexistence of different races and peoples. The concept of number has always been accompanied by non-numeric concepts.
For example, one, two, many... These non-numerical concepts have always protected the realm of mathematics. Mathematics gave a finished look to all the sciences where it was applied. In Europe, there is a division into the humanities and natural sciences according to the degree of influence of mathematics on these parts.
The oldest math problem.
It was invented 2650 years ago and in the Russian version it sounds like this:
On the way to Dijon I met a husband and his seven wives. Each wife has seven bales, Each bale has seven cats. How many cats, packs and wives peacefully moved to Dijon?
The biggest numbers.
The largest number found in explanatory dictionaries and having the name - the power of 10, is the centillion, first used in 1852. This is a million to the hundredth power, or a unit with 600 zeros.
One followed by one hundred zeros is called a googol. This term was proposed by the 9-year-old nephew of Edward Kasner (USA).
10 to the power of a googol is called a googolplex.
10 - ten

One of the essential indicators of the intellectual development of the child and its age-appropriateness is logical thinking. It develops in stages, starting from the simplest to the most complex. And thanks to modern developing technologies and unusual tasks, from boring and monotonous training, it can be turned into exciting game which is sure to please both parents and children.
The development of logic is one of the most important aspects intellectual development
Patterns of development of thinking in preschool age
In general, the thinking of preschoolers goes through three basic stages in its development:
- Visual-effective thinking allows you to solve the problems that arise before the child by manipulating the objects around him.
- Visual-figurative thinking begins to develop in the preschool period. It already allows the child to solve some problems in the mind with the help of the images in his memory.
- Verbal-logical thinking enables the child to think with the help of not the objects themselves, but their verbal designations. This type of thinking manifests itself already in the older preschool age.
Board games - The best way development of logical thinking Logic is one of the highest stages in the development of thinking.
General rules for the development of logic in a child
Play is the main activity in preschool age. However, despite this, logic plays an important role for preschoolers. Imagination during this period is still not well developed, and in order to make learning easier and more efficient, it is necessary to use a maximum of visual material in the process of classes: toys, pictures, puzzles, counting sticks, etc. Bright didactic material will turn any activity into an exciting game in which the child will be happy to take part.
Geometric figures- development of logic in a game form As the child grows older, he will need less and less demo material. And the solution of an increasing number of tasks will occur in the mind, by connecting already verbal-logical thinking.
Logical thinking in early preschool age
The younger preschool age covers the period from 2 to 4 years. At this time, the child learns to compare objects, classify according to such elementary features as color, shape, size.
Developing classes at this age are best done using bright toys or didactic cards. It is desirable that the images are as simple as possible and contain a minimum of distracting details.
Classes with the baby teaches him to think logically Logic tasks for younger preschoolers are varied. Typical exercises for the development of logic at this age can be:
"Put it in order"
The game helps the child understand cause and effect relationships, and also improves his perception of time.
For this exercise, you will need cards with pictures of animals and their babies. Children can be offered to pick up a pair for each card, having previously laid out adult animals in front of him and giving him cubs. After all the cards have taken their places, it will be possible to explain to the child that a chicken or a rooster grows out of a tiny chicken, a dog grows out of a puppy, etc. Over time, this task can be made more difficult by offering the child pictures of scenes from his favorite fairy tales. And offer to put them in order, restoring the plot.
Matching game "Finish the chain"
The child is offered logical chains of objects or pictures belonging to a certain class: these can be flowers, trees, animals or birds. And next to it is a group of different pictures, among which there should be one belonging to the items in the chain. The task of the child is to complete the chain with a suitable element.
This task, despite its simplicity, well develops the ability to generalize and analyze, compare and classify.
"Whose subject?"
In this task for preschoolers, you can invite the child to name:
- items used by representatives of various professions;
- details of certain machines or devices;
- parts of the human body, animals, birds;
- house elements.
Online game Find exactly the same cat - the kid can play on the Internet "Remove the excess"
A group of pictures is laid out in front of the child, depicting various items, or toys, among which there should be one extra that does not fall under the general category. The task of the child is to find and remove this object with the help of logical thinking. It is very desirable that the child could also explain his choice, telling why this or that object turned out to be superfluous.
Game Choose the smallest object Over time, the task can be somewhat complicated by adding specific items. natural phenomena, flowers, etc. The logical connections between them are somewhat more complicated, and in order to cope with this task, the child will need to try very hard.
Classes for the development of logic in senior preschool age
The senior preschool period is marked by the intensive development of many mental processes. In particular, by the age of four, children begin to manifest verbal-logical thinking, which allows them not only to solve certain tasks, but also to clearly argue their position.
Joint games develop logic in older preschoolers The child is no longer in need of visualization due to a fairly well-developed imagination and an increase in memory capacity. And although it is still desirable to use all kinds of didactic material in the classroom, as early as 4 years old, you can offer your child to solve some problems in his mind.
Here are just some logic tasks for older preschoolers.
"Ranging"
The development of the thought processes of preschoolers is very well facilitated by ranking (for example, by size, color, and later - the severity of a particular feature). It is imperative to clarify to the child what exactly serves as the basis for ranking.
Spot the Difference game is one of the varieties of ranking games "General and private"
To the elder preschool age in the conceptual apparatus of the child, ideas about the general and the particular are already fully formed. Therefore, he can already be offered to complete tasks on this topic.
Logic maze is a favorite pastime for preschoolers Games for the formation of ideas about the general and the particular are quite simple. It is enough just to lay out objects or cards with objects of the same type in front of the child and invite the child to determine the logical connections between them, naming them in one word. Just like in previous games, here you need to move from simple to complex, first using the simplest categories, where the common feature will lie on the surface. And over time - to complicate the task, expanding the number of groups used.
If in the process of completing tasks, preschoolers will have any difficulties, be sure to talk to them about it. And solve problems together.
The thought processes, in particular, logic, of preschool children develop at a fairly intensive pace and by the time they enter school they are already at a good level, which allows them to master the school curriculum as efficiently as possible.

80. A problem invented by the learned monk and mathematician from Ireland Alcuin (735-804).
The peasant needs to be transported across the river wolf, goat and cabbage. 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 the wolf with the goat, then the wolf will eat the goat, and if you leave the goat with the 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 shore, where he leaves him, but he takes and carries the goat back to the first shore. Here he leaves her and transports the cabbage to the wolf. Then, returning, he carries a goat, and the crossing ends happily. Solution 2: First, the farmer again transports a goat. But the second one can take the cabbage, take it to the other side, 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 it to the other side.

261. In the dense Murom forest, ten springs gush out of the ground dead water, they are numbered from #1 to #10.
From the first nine sources, everyone can take dead water, but source No. 10 is located in Koshchei's cave, into which no one except Koshchei himself can get.
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 greater. For example, if he drinks from the seventh source, then he must definitely drink 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.
Ivan the Fool challenged Koshchei to a duel. The terms of the duel were as follows: each brings a mug of liquid with him and gives it to his opponent to drink. Koschei was delighted: “I will give poison number 10, and Ivan the Fool will not be able to escape! And I myself will drink the poison that Ivanushka the Fool will bring me, I will drink it with my tenth and be saved!
On the appointed day, both opponents met at the agreed place. They honestly exchanged mugs and drank what was in them. It turned out that Koschei died, but Ivan the Fool remained alive! How did it 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 ..

The missionary was captured by the savages, who put him in prison and said: “From here there are only two ways out - 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 lover; you can ask any of them only one question.” What question should be asked to get out to freedom?
It is necessary to apply to any of the warriors with next question: "If I ask you if this exit leads to freedom, will you answer me yes?" With such a formulation of the question, the warrior who lies all the time will be forced to tell the truth. Suppose you, pointing him to the exit to freedom, say: “If I ask you, does this exit lead to freedom, will you answer me “yes”?” In this case, it will be true if he answers “no”, but he needs to lie, and therefore he is forced to say “yes”.

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 the 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 travel, which, surprisingly, no one uses. As you know, the Earth rotates around its axis, and quite quickly (in just 24 hours, each point of the earth's equator travels approximately 40,000 km - a path equal to the length of the equator). So, instead of going somewhere by train, or flying by plane, or sailing on a ship, it is enough for us to rise high above the ground on hot-air balloon or an airship and stay there motionless for some time. During this time, the Earth will turn to us with another part of its surface and it will only be necessary to descend into Right place. Is this reasoning correct? If not, what is wrong with it?
This way of travel is, of course, unsuitable. The atmosphere, attracted by the Earth, rotates with it. And even if the atmosphere were motionless, then, having risen into it from the rotating Earth, we would continue the earth's movement by inertia for some time. In addition, if the atmosphere were motionless, and the Earth would continue to rotate in it (and fast enough: see the condition of the problem), then in this case the greatest hurricane would not stop raging on Earth, which would make impossible not only any travel but also human life itself.
Correct answer
274. Is it possible to boil water on an open flame in a paper box?
The question of the problem, at first glance, seems very strange, because if you hold paper over a 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 from the flame is taken away by the boiling water, the paper cannot be heated to desired temperature and therefore does not light up. It is only necessary that the paper is thick enough, otherwise the water will simply tear it and pour out onto the flame. A cardboard box is quite suitable for boiling water. The same explanation underlies such a phenomenon as a fireproof piece of paper tightly wound around a metal rod (or steel nail) and brought into the flame of a candle. The rod will take the heat of the fire, preventing the paper from heating up to the desired temperature and catching fire.

Correct answer
279. Katya lives on the fourth floor, and Olya lives on the second. Rising to the fourth floor, Katya overcomes 60 steps. How many steps does Olya need to climb 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 two times lower than her. Actually it is not. When Katya goes up to the fourth floor, she overcomes 3 flights of stairs between floors. This means that there are 20 steps between two floors: 60: 3 = 20. Olya climbs from the first floor to the second, therefore, she overcomes 20 steps.

280. How to pour exactly half of a mug, ladle, pan and any other dish of regular cylindrical shape, filled to the brim with water, without using any measuring instruments?
Any dish of the correct cylindrical shape, when viewed from the side, is a rectangle. As you know, the diagonal of a rectangle divides it into two equal parts. Similarly, a cylinder is bisected by an ellipse. It is necessary to drain water from a cylindrical dish filled with water until the surface of the water on one side reaches the corner of the dish, where its bottom meets the wall, and on the other side, the edge of the dish through which it is poured. In this case, exactly half of the water will remain in the dishes:

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.

287. It is often said that one must be born a composer, or an artist, or a writer, or a scientist. Is this true? Is it really necessary to be born as 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 understood literally: is it necessary to be born in order to engage in any type of activity; and this question can 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 by hard work.

288. In order to see, it is not at all necessary to have eyes. We see without the right eye. We also see without the left. And since we have no other eyes besides the left and right eyes, it turns out that neither eye is necessary for vision. Is this statement correct? If not, what is wrong with it?
The reasoning is, of course, wrong. Its external correctness is based on the almost imperceptible exclusion of one more option, which in this reasoning also had to be considered. This is an option when not a single eye sees. It was he who was omitted: “Without the right eye we see, without the left 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 two together we cannot see, which means that we see either with one eye, or the other, or two together, but we cannot see without eyes, which, thus necessary for vision."

289. The parrot has lived less than 100 years and can only answer yes and no questions. How many questions does he need to ask to find out his age?
At first glance, it may seem that a parrot can be asked up to 99 questions. In fact, you can get by with a much smaller number of questions. Let's ask him like this: "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 year to 50 years old. The number of options for his age after the first question is halved. The next similar question: “Are you more (you can ask - less) 25 years old?”, “Are you more (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 be asked only 7 questions.

290. One man who fell into captivity tells the following: “My dungeon was in the upper part of the castle. After many days of effort, I managed to break one of the bars in the narrow window. It was possible to crawl through 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 be able to go down it. Then I remembered how one wise man lengthened a blanket that was too short for him, cutting off part of it from below and sewing it on top. So I hurried to split the rope in half and re-tie the two resulting parts. 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 it most likely might seem, but along it, making two ropes of the same length out of it. When he tied the two pieces together, the rope became twice as long as it was at first.
