Difficult tasks. Tasks for logical thinking

Preschoolers solve this problem in 5-10 minutes. For some programmers, it takes up to an hour to complete it. But many people, after writing a few sheets of paper, give up.

Parking space number

A six-year-old child usually takes no more than 20 seconds to solve this problem. But unprepared adults, she often enters into a stupor. So what number is hidden under the car?

A riddle for a genius

A genius finds a solution in 10 seconds. Bill Gates - in 20 seconds. Graduate of Harvard (Harvard University) - in 40 seconds. If you found the answer in 2 minutes, then you belong to the top 15% of the most gifted people. 75% of people are not able to solve this problem.

Ruler of the island

The autocratic ruler of one island wanted to prevent aliens from settling on the island. Wanting to keep the appearance of justice, he issued an order according to which anyone who wants to settle on the island should, after thinking well, make any statement, and after a preliminary warning that his life depends on the content of this statement. The order read: “If the stranger tells the truth, he will be shot. If he tells a lie, he will be hanged." Can an alien become a resident of the island?

Project approval

According to the agreement, the procedure for approving a new project, in the development of which institutions A, B, C participate, is as follows: if A and B participate in the approval first, then institution C must also join the participation. If approval occurs first in institutions B and C, Institution A also joins. The question is: are such cases possible when approving a project, when only institutions A and C would take part in it, while the participation of institution B would not be necessary (while maintaining an agreement on the procedure for approving projects)?

Two tribes

Two tribes live on the island: well done. Who always tell the truth, and liars who always lie. The traveler met an islander, asked him who he was, and when he heard that he was from a tribe of fellows, he hired him as a guide. They went and saw another islander in the distance, and the traveler sent his guide to ask him what tribe he belonged to. The guide returned and said that he claims to be from a tribe of fellows. The question is: was the conductor a good fellow or a liar?

Aborigines and aliens

Before the court are three people, of which each can be either an aborigine or an alien. The judge knows that natives always answer questions truthfully, and aliens always lie. However, the judge does not know which of them is an aborigine and which is an alien. He asks the first one, but does not understand his answer. Therefore, he asks first the second, and then the third about what the first answered. The second says that the first said that he was an aborigine. The third says that the first called himself an alien. Who were the second and third defendants?

beetle on tape

The beetle went on a journey. He crawls along the tape, the length of which is 90 centimeters. At the other end of the ribbon, two centimeters from the end, is a flower. How many centimeters will the beetle have to crawl to the flower: 88 or 92 (provided that it crawls all the time on one side and only at the end can it cross over to the other side through the end of the tape)?

Purchase

Marina took a long time choosing which jug to buy. Finally chose. The saleswoman put the purchase in a box. What did Marina buy? How many jugs did the saleswoman put on the shelves on which they stood before?

Tourist

The tourist walked to the lake. He came to a crossroads, from where one road led to the right and the other to the left; one went to the lake, the other did not. Two guys were sitting at the crossroads, one of them always told the truth, the second always lied. Both of them answered any question with either "yes" or "no". All this was known to the tourist, but he did not know which of them was telling the truth and which was lying; he also did not know which road led to the lake. The tourist put only one question to one of the guys. What was the question, since he knew from the answer which road leads to the lake?

broken window

There were nine students left in the class during the break. One of them broke the window. The teacher's question was answered as follows:

How many triangles? What team?

Read carefully and do not write anything down: Torpedo tops the standings, Spartak is in fifth place, and Dynamo is right in the middle between them. If Lokomotiv is ahead of Spartak, and Zenit takes place immediately behind Dynamo, then which of the listed teams is in second place? You have 30 seconds to think.

Project approval procedure

The enterprise has three workshops - A, B, C, agreed on the procedure for approving projects, namely: 1. If workshop B does not participate in the approval of the project, then workshop A does not participate in this approval. 2. If workshop B participates in approval of the project, then shops A and C take part in it. The question is: under these conditions, is shop C obliged to take part in the approval of the project, when shop A participates in the approval?

An evening walk

Which of these nine mustaches went on an "evening walk"?

7 buttons

Which of the 7 buttons should be pressed. For the bell to ring? It is recommended to find the path mentally.

Make a table

In the Moscow semi-finals of the European Basketball Championship, which took place in Soviet times, the places were distributed as follows: the USSR - 14 points, Italy and Czechoslovakia - 12 points each, Israel - 11, Finland - 10, East Germany and Romania - 9 points each and Hungary - 7 points. According to the position. Each team received 2 points for a win, 1 point for a loss, and 0 points for a no-show. Draws were not allowed. Make a summary table of the results of the games if it is known that the Finnish team won against the Italian team and lost to the Romanian team.

Explanation is inevitable

On Tuesday, at about 10 am, a stranger burst into Inspector Warnicke's room. He was extremely excited. His hands were trembling, his tousled hair stuck out in all directions. A few minutes later, after lighting a cigarette and calming down, the visitor began his story: - This morning I returned from vacation. All night I had to shake on the train. I didn't get enough sleep and when I got home I decided to lie down on the sofa. From fatigue, I did not immediately notice that the piano had disappeared from the room, and the coffee table and armchair had been moved. On this sheet of paper, I drew a plan for the arrangement of the furniture in the room before I left. - Here's what, dear, - said Inspector Varnicke, glancing briefly at the drawing, - First of all, it's quite clear to me that you didn't have a piano at all. Now let's find out why you needed this lie. Why did Inspector Varnicke doubt the veracity of the visitor's story?

LOGIC TASKS

Logic tasks, as well as mathematics, is called "mind gymnastics". But unlike mathematics, logic tasks- this is an entertaining gymnastics, which in a fun way allows you to test and train thought processes, sometimes in an unexpected perspective. To solve them, you need quick wit, sometimes intuition, but not special knowledge. Solving logic problems is to thoroughly analyze the condition of the problem, to unravel the tangle of contradictory connections between characters or objects. Logic tasks for children- these are, as a rule, whole stories with popular characters, in which you just need to get used to, feel the situation, visualize it and catch the connections.

Even the most difficult logic puzzles do not contain numbers, vectors, functions. But the mathematical way of thinking is necessary here: the main thing is to comprehend and understand the condition logical task. The most obvious decision on the surface is not always the right one. But more often than not, solving a logic problem turns out to be much simpler than it seems at first glance, despite the confusing condition.

Interesting logic tasks for children in a variety of subjects - mathematics, physics, biology - arouse their increased interest in these academic disciplines and help in their meaningful study. Logic tasks for weighing, transfusion, tasks for non-standard logical thinking will help to solve everyday problems in a non-standard way in everyday life.

In the process of decision logic tasks you will get acquainted with mathematical logic - a separate science, otherwise called "mathematics without formulas." Logic as a science was created by Aristotle, who was not a mathematician, but a philosopher. And logic was originally part of philosophy, one of the methods of reasoning. In the work "Analytics" Aristotle created 20 schemes of reasoning, which he called syllogisms. One of his most famous syllogisms is: “Socrates is a man; all men are mortal; So Socrates is mortal. Logic (from other Greek. Λογική - speech, reasoning, thought) is the science of correct thinking, or, in other words, "the art of reasoning."

There are certain methods solving logic problems:

way of reasoning, with the help of which the simplest logical problems are solved. This method is considered the most trivial. In the course of the solution, reasoning is used that consistently takes into account all the conditions of the problem, which gradually lead to a conclusion and the correct answer.

tables way, used in solving text logic problems. As the name implies, solving logical problems consists in building tables that allow you to visualize the condition of the problem, control the process of reasoning, and help draw the right logical conclusions.

graphs way consists in sorting out possible scenarios for the development of events and the final choice of the only correct solution.

flowchart method- a method widely used in programming and solving logical transfusion problems. It consists in the fact that, first, operations (commands) are allocated in the form of blocks, then the sequence of execution of these commands is established. This is the block diagram, which is essentially a program, the execution of which leads to the solution of the task.

billiard way follows from the theory of trajectories (one of the sections of probability theory). To solve the problem, it is necessary to draw a billiard table and interpret the actions of the movements of the billiard ball along different trajectories. In this case, it is necessary to keep records of possible results in a separate table.

Each of these methods is applicable to solving logical problems from different areas. These seemingly complex and scientific techniques can be used in solving logic problems for grades 1, 2, 3, 4, 5, 6, 7, 8, 9.

We present you with a variety of logical tasks for grades 1, 2, 3, 4, 5, 6, 7, 8, 9. We have selected for you the most interesting logic puzzles with answers which will be interesting not only for children, but also for parents.

  • choose for the child logic tasks according to his age and development
  • do not rush to open the answer, let the child find it himself logical solution tasks. Let him come to the right decision himself and you will see what pleasure and a sense of delight he will have when his answer coincides with the given one.
  • during solving logic problems Leading questions and indirect clues indicating the direction of reflection are acceptable.

With our selection logical tasks with answers you will really learn how to solve logical problems, expand your horizons and significantly develop logical thinking. Dare!!!

Logic problem solving — the first step in child development.

E.Davydova

Logic is the art of coming to an unpredictable conclusion.

Samuel Johnson

Without logic, it is almost impossible to bring into our world ingenious finds of intuition.

Kirill Fandeev

A person who thinks logically stands out nicely against the background of the real world.

American saying

Logic is the morality of thought and speech.

Jan Lukasiewicz

Good day, dear friends! Do you remember what grades you got in school? I remember. There are no triples in my certificate. But during any year of study there were triples, deuces, and even cola sometimes happened. So I think, who is Alexandra, my daughter, like? Excellent student, hangs on the honor roll! Apparently those additional exercises that we do with her are bearing fruit.

Lesson plan:

Exercise 1

A very interesting exercise! Useful not only for children, but also for adults. This exercise is used as a test at the casting of radio hosts. Imagine, you come to the casting, and they say to you: “Come on, my friend, connect us a chicken with a pole.” In all seriousness, they say so!

The meaning is precisely in this, it is necessary to combine two absolutely unrelated concepts. Radio presenters need this in order to quickly and beautifully compose lead lines to songs during live broadcasts, for easy transitions from one topic to another.

Well, the kids are suitable for the development of creative, creative, quick thinking.

So how do you connect a chicken with a pole? Lots of options:

  1. The chicken walks around the post.
  2. The chicken was blind, walked and crashed into a pole.
  3. The chicken was strong, hit the pole, and it fell.
  4. The pillar fell right on the chicken.

Do you want to work out? Good. Connect:

  • chamomile with milk;
  • headphones with a jellyfish;
  • moon boots.

Exercise 2. Word Breakers

If in the previous exercise we connected, then in this we will break one long word into many short ones, consisting of letters of a large word. According to the rules, if a letter occurs once in a long word, then it cannot be repeated twice in short words.

For example, the word "switch" breaks down into:

  • tulle;
  • key;
  • beak.

I don't see any more options, do you?

You can break any long words, for example, “holiday”, “picture”, “towel”, “polar explorer”.

Exercise 3. Puzzles

Solving puzzles helps to think outside the box, creatively. Teaches the child to analyze.

Rebuses may contain images, letters, numbers, commas, fractions, placed in a very different order. Let's try to solve some simple puzzles together.

  1. On the first we see the syllable "BA" and "barrel". Connect: BA + Barrel = Butterfly.
  2. On the second, the principle is the same: Baran + KA = Bagel.
  3. The third is more difficult. Cancer is drawn, and next to it is “a = y”. So in the word cancer, the letter "a" must be replaced with the letter "y", we get "hands". To this we add another "a": hand + a = hand.
  4. The fourth rebus with a comma. Since the letter “A” is the first, the guess word begins with it. Next, we see the “fist”, after the picture there is a comma, which means that the last letter must be subtracted from the word “fist”. Let's get "cool". Now we combine everything together: A + kula = shark.
  5. The fifth rebus is only at first glance difficult. You need to remove the letter “and” from the word “saw”, and read the word “cat” backwards. As a result, we get: pla + current = handkerchief.
  6. The sixth, fully alphabetic rebus. Everything is clear with the first and last letters, but what about the middle? We see the letter "o" drawn in the beech "t", so let's say "in t o". We connect: A + WTO + P \u003d AUTHOR.

Trained? Now try to solve the puzzle yourself.

You can share your answers in the comments. You will find many puzzles in children's magazines and.

Exercise 4. Anagrams

Can an orange be turned into a spaniel and vice versa? "Easily!" anagram lovers will answer. You don't even need a magic wand.

An anagram is a literary device that consists in rearranging the letters or sounds of a certain word (or phrase), which results in another word or phrase.

Just as easily, a dream turns into a nose, a cat into a current, and a linden into a saw.

Well, shall we try? Let's make it so:

  • the "carriage" flew to the stars;
  • "word" grew on the head;
  • "lace" learned to fly;
  • "atlas" became edible;
  • "pump" settled in the forest;
  • "mote" became transparent;
  • the “roller” was placed on the table before dinner;
  • "bun" learned to swim;
  • "chamomile" was spinning by the lantern on summer evenings;
  • "Park" could not live without water.

Exercise 5. Logic problems

The more logic puzzles you solve, the stronger your thinking becomes. After all, it is not for nothing that they say that mathematics is gymnastics for the mind. Indeed, when solving some of them, you directly feel how the brain moves.

Let's start with the simpler ones:

  1. Kolya and Vasya solved problems. One boy decided at the blackboard, and the other at the desk. Where did Vasya solve problems if Kolya did not solve them at the blackboard?
  2. Three old grandmothers live in the same entrance, on the third, fifth and seventh floors. Who lives on what floor, if grandmother Nina lives above Valya's grandmother, and Galya's grandmother lives below Valya's grandmother?
  3. Yura, Igor, Pasha and Artem finished in the top four in the running competition. Who took what place? It is known that Yura did not run first or fourth, Igor ran after the winner, and Pasha was not the last.

And the next three problems Sashulya brought from the Mathematical Olympiad. These are tasks for the third grade.

“The gardener planted 8 seedlings. Of all but four, pear trees have grown. All but two pear trees grow pears. Pears from all fruit-bearing pear trees except one are not tasty. How many pear trees have tasty pears?”

“Vasya, Petya, Vanya wear ties of only one color: green, yellow and blue. Vasya said: "Petya does not like yellow." Petya said: "Vanya wears a blue tie." Vanya said: "You are both deceiving." Who prefers what color if Vanya never lies?

And now attention! A task of increased difficulty! "On the backfill," as they say. I couldn't solve it. I suffered for a long time, and then I looked at the answers. She is also from the Olympics.

“The traveler needs to cross the desert. The transition lasts six days. The traveler and the porter who will accompany him may take with him a supply of water and food for one person for four days each. How many porters will the traveler need to realize his plan? Enter the smallest number."

If you still fall asleep on any task, then contact me, I will help)

Exercise 6. Match puzzles

Matches are not toys for children! A tool for training thinking. For safety reasons, I suggest replacing matches with counting sticks.

These simple little sticks make very complex puzzles.

First, let's warm up:

  • fold two identical triangles from five sticks;
  • of seven sticks, two identical squares;
  • remove three sticks to make three identical squares (see picture below).

Now more difficult:

Move three sticks so that the arrow flies in the opposite direction.

The fish also needs to be turned in the other direction, while shifting only three sticks.

After shifting only three sticks, remove the strawberry from the glass.

Remove two sticks to make two equilateral triangles.

The answers can be found at the end of the article.

Exercise 7

And now let's work as Sherlock Holmes! Let us seek the truth and discover lies.

Show the child two pictures, on one of which depict a square and a triangle, and on the other a circle and a polygon.

And now offer cards with the following statements:

  • some figures on the card are triangles;
  • there are no triangles on the card;
  • there are circles on the card;
  • some of the figures on the card are squares;
  • all shapes on the card are triangles;
  • there are no polygons on the card;
  • There are no rectangles on the card.

The task is to determine whether these statements are false or true for each picture with figures.

A similar exercise can be carried out not only with geometric shapes, but also with images of animals. For example, put a cat, a fox and a squirrel on the picture.

Statements can be as follows:

  • all these animals are predators;
  • there are pets in the picture;
  • all the animals in the picture can climb trees;
  • all animals have fur.

Pictures and statements to them can be selected independently.

Exercise 8. Instruction

We are surrounded by a variety of things. We use them. Sometimes we do not pay any attention to the instructions that are attached to these items. And it also happens that there are simply no instructions for some very necessary items. Let's fix this misunderstanding! We will write the instructions ourselves.

Take, for example, a comb. Yes, yes, the usual comb! That's what we got with Alexandra.

So, instructions for using the comb.

  1. A comb is a device for making hair smooth and silky, made of plastic.
  2. Use a comb should be with increased shaggy and curly.
  3. In order to start combing, approach the comb, gently take it in your hand.
  4. Stand in front of a mirror, smile, bring the comb to the roots of your hair.
  5. Now slowly move the comb down to the ends of your hair.
  6. If there are obstacles in the form of knots on the way of the comb, then run the comb over them several times with weak pressure, while you can scream a little.
  7. Each strand of hair is subject to processing by a comb.
  8. Combing can be considered finished when the comb does not meet a single knot on the way.
  9. After combing, it is necessary to rinse the comb with water, put it in a place specially designated for it.
  10. If a tooth has broken off a comb, you need to throw it in the trash.
  11. If all the teeth of the comb have broken off, send it after the tooth.

Try writing instructions for a pot, or slippers, or a glasses case. It will be interesting!

Exercise 9. Making up a story

Stories can be composed in different ways, for example, based on a picture or on a given topic. By the way, this will help. And I suggest you try to compose a story based on the words that must be present in this story.

As always, an example.

Words are given: Olga Nikolaevna, poodle, sequins, turnip, salary, gray hair, castle, flood, maple, song.

Here's what happened to Sasha.

Olga Nikolaevna walked down the street. On a leash, she led her poodle Artemon, the poodle was all shiny. Yesterday he broke the lock on the locker, got to the box of glitter, and poured it all over himself. And Artemon gnawed through the pipe in the bathroom and made a real flood. When Olga Nikolaevna came home from work and saw all this, gray hair appeared in her hair. And now they were going for turnips, as turnips calm the nerves. And the turnip was expensive, worth half the salary. Before entering the store, Olga Nikolaevna tied the poodle to a maple tree and, singing a song, went inside.

Now try it yourself! Here are three sets of words:

  1. Doctor, traffic light, headphones, lamp, mouse, magazine, frame, exam, janitor, paper clip.
  2. First grader, summer, hare, button, gap, bonfire, Velcro, shore, plane, hand.
  3. Konstantin, jump, samovar, mirror, speed, sadness, trip, ball, list, theater.

Exercise 10

We have already worked as detectives. Now I propose to work as a police officer. The fact is that the words in well-known proverbs and sayings violated the order. We will deal with violators of the order. Try to arrange the words the way they are supposed to stand.

  1. Food, comes, time, in, appetite.
  2. You will pull out, not, labor, from, a fish, a pond, without.
  3. Measure, one, a, one, seven, cut, one.
  4. And, ride, sled, love, carry, love.
  5. Waiting, no, seven, one.
  6. Word, cat, and, nice, kind.
  7. One hundred, a, rubles, have, don't, have, friends, a hundred.
  8. Falls, not, apple trees, far, apple, from.
  9. Flowing, stone, not, water, recumbent, under.
  10. Autumn, consider, by, chickens.

I want to clarify. We don't do this on purpose. That is, it doesn’t happen that I say: “Come on, Alexandra, sit down at the table, let’s develop thinking!” No. All this in between times, if we go somewhere, we go, before going to bed instead of books. It is very interesting to do it, so you don’t have to force anyone.

Well, now the promised answers to matchstick puzzles!

Puzzle Answers

About two triangles of five matches.

About two squares out of seven.

We get three squares.

Expand the arrow (watch the color of the sticks).

We turn the fish.

And about two equilateral triangles.

I recently found this video on the internet. It has completely different exercises. We tried, until it turns out with difficulty. Well, let's practice. See if you can use it too.

Different types of puzzles for adults will help you develop your memory and quick wit - logic tasks, complex, funny or tricky questions, various intellectual mathematical games.

Logic games and puzzles for adults

To solve a variety of logic puzzles, a high level of education is not required, starting to solve them is a useful activity for absolutely everyone.A variety of trick riddles for adults train non-standard thinking, which will help in everyday life to quickly find rational solutions in difficult everyday situations.

Riddles for adults

This type of task will allow you to immediately check the correctness of your solution. What are these short riddles good for? You can thematically, according to the answers, make a selection for a specific holiday or feast to entertain guests. Depending on the composition of the invitees, riddles with a trick, tasks that will make your friends laugh, or math tasks are good.

With a catch

In tasks with a trick, the question itself often looks illogical at first glance, for example: what language is spoken silently? When the answer is announced, the first reaction of a person is manifested as disagreement with him. At first glance, the question and the chosen answer are connected in an unusual way and with a double subtext. But after a little thought, you can’t help but agree that such a daring decision is correct and very logical (answer: in sign language).

funny

It is a pleasure to play solving funny riddles. While your guests will express answers to tricky questions, the whole company is guaranteed to be shaken by explosions of laughter.

Mathematical

In such riddles, one must guess the given figure, or calculate the result, relying not so much on arithmetic as on quick wits. An answer that looks obvious and seems to lie on the surface is often wrong.

Mind games

Logic tasks for adults are multi-way combinations for training thinking. To solve them correctly, you need to think through the actions several steps ahead. Such tasks are relatively difficult, often they are in the form of original pictures, where you need to rearrange or finish some elements.

Logic tasks for adults

Often, logical tasks involve the use of improvised materials: matches, paper, pencils, etc. The solution of such tasks is multi-way, it requires the construction of a strategy - for example, to calculate how to add matches or connect dots in a certain way.

Logic tasks are perhaps the most effective tool for developing logic and thinking in both children and adults.

Solving a logic problem involves a complex thought process. This is the consistent performance of certain logical actions, working with concepts, using various logical constructions, building a chain of precise reasoning with correct intermediate and final conclusions.

Unlike most mathematical and other types of problems, when solving logical problems, the key is not to find the quantitative characteristics of an object, but to determine and analyze the relationships between all objects of the problem.

Take a holistic approach

Among the whole variety of logical tasks, children often choose a couple of their favorite categories and immerse themselves in solving them. is that enough?

Surely most of us at least once passed tests for the level of logic. Most of them are made up of some syllogisms or trick questions. We do not offer such tests, because we know for sure that it is impossible to determine the level of development of logical thinking with the help of a dozen or two questions, even approximately. As well as developing non-standard thinking, solving only certain types of logical problems.

Classical logical, combinatorial and truth problems, regularities and mathematical puzzles, problems about figures in space and sweeps, for permutations and movement, for weighing and transfusion; solved from the end, with the help of tables, segments, graphs or Euler circles - this is far from the whole variety of logical tasks, in the solution of which all kinds of mental operations are activated and creative, non-standard thinking develops.

Logic is a yummy for the mind

This is exactly what the students wrote on the blackboard before the start of one of the classes in our logic circle. What is the beauty of logical problems?

  • they will be equally interesting for children who are passionate about mathematics and for “humanists”;
  • many of them do not require knowledge of the school curriculum;
  • even a preschooler without reading skills can solve them (for example, sudoku, rebuses, matchstick puzzles, gears and other tasks in pictures).

Children love to solve logical problems and riddles. They are interested! When I worked at school, I saw that the guys cope with the program, mechanically remembering the way to solve certain typical problems.

And tasks with asterisks immediately enlivened the class, both strong and weak students were included in the discussion process. At home, the children already could and wanted to explain this task to their parents. But even these problems with asterisks were located on the pages of the textbook in a random way, no system was developed.

Bitno Galina Mikhailovna

head teacher of LogicLike, teacher of the highest category

Only a systematic and integrated approach creates favorable conditions for the formation of non-standard thinking. "Food for thought" should also be balanced and varied. Try it yourself and invite your children to solve just such a selection of problems. This will help identify those links in the logic that need to be worked harder.

Try it yourself

In the Logiclike online platform, created to develop logic and mathematical abilities in children aged 5-12, the authors tried to implement everything that is often so lacking for both students and teachers in school curricula. Consistency, involvement, interactivity, visibility, motivation ... But first of all, it is food for the mind, the very “yummy” that makes the child think, reason, test his strength, be creative and rejoice when he manages to find the right solution.

  • If you want to develop non-standard thinking and flexible logic in a child, give him a good exercise for the mind in the form of a variety of logical problems, for which you need to use different logical laws and solution methods (method from the end, tabular method, using graphs or Euler circles, etc.). e.)
  • Approach learning systematically: from theory to tasks, from simple to complex, from getting to know new types of tasks to reflection.
  • Consider the specifics of thinking in children of primary school age - use visual images and visual materials.
  • It is important not to impose a solution method on children, but to try to analyze it so that they themselves, through logical reasoning, find the correct answer.
  • Introduce game elements into the learning process, use the learning capabilities of IT.
  • Logic classes, like sports training, need regularity and a gradual increase in the complexity of tasks.

The tasks of this section are designed for different age groups and are suitable for solving: adults, students, teenagers, schoolchildren, children.

A logic task is a task that, as a rule, requires logical thinking, ingenuity, and sometimes the use of non-standard thinking, rather than high-level special knowledge. Therefore, its solution will help you both test and increase your quick wit, logical thinking.





In a forest dispensary in a clearing, two athletes play table tennis. After another strong blow with a racket, the tennis ball flew far and rolled into a steel pipe, vertically dug deep (several meters) into the ground. The ball ended up at the very bottom of the pipe (a few meters from the surface of the earth). For athletes, this was the only ball. Can you please tell me how to pull out a tennis ball without much effort, without resorting to digging such a long pipe?
