Ruler of the IslandThe autocratic ruler of one island wanted to prevent aliens from settling on the island. Wanting to maintain the appearance of justice, he issued an order according to which anyone wishing to settle on the island must, after thinking carefully, make any statement, and after a preliminary warning that his life depended on the content of this statement. The order read: “If the alien tells the truth, he will be shot. If he tells a lie, he will be hanged." Can an alien become an island resident?
Project approvalAccording to the agreement, the procedure for approving a new project in the development of which institutions A, B, and C participate is as follows: if A and B participate in the approval first, then institution B must also participate. 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 B would take part in it, while the participation of institution B would not be necessary (while maintaining the agreement on the procedure for approving projects)?
Two tribesThere are two tribes living on the island: well done. Those who always tell the truth, and liars who always lie. The traveler met the 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 to what tribe he belonged. The guide returned and said that he claimed to be from a tribe of fellows. The question is: was the guide a good guy or a liar?
Aborigines and AliensThree people stand before the court, each of whom can be either an aborigine or an alien. The judge knows that natives always answer questions truthfully, but aliens always lie. However, the judge does not know which of them is a native 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, what the first answered. The second one says that the first one said he was an Aborigine. The third says that the first called himself an alien. Who were the second and third defendants?

Explanation is inevitableOn Tuesday at about 10 o'clock in the morning a stranger burst into Inspector Warnicke's room. He was extremely excited. His hands were shaking, his tousled hair stuck out in all directions. A few minutes later, having lit a cigarette and calmed down, the visitor began his story: - This morning I returned from vacation. I had to shake on the train all night. I didn’t get enough sleep and, when I came home, I decided to lie down on the sofa. Because of fatigue, I did not immediately notice that the piano had disappeared from the room, and the coffee table and armchair had been moved out of place. On this piece of paper I drew a plan for the arrangement of furniture in the room before I left. “Here’s what, dear,” said Inspector Warnicke, taking a quick look at the drawing, “First of all, it’s absolutely 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 Warnicke doubt the veracity of the visitor's story?
LOGIC PROBLEMS
Logic problems, just like mathematics, is called “mental gymnastics.” But, unlike mathematics, logic problems is an entertaining gymnastics that allows you to test and train your thought processes in a fun way, sometimes from an unexpected perspective. Solving them requires intelligence, sometimes intuition, but not special knowledge. Solving logic problems consists in thoroughly analyzing the conditions of the problem, unraveling the tangle of contradictory connections between characters or objects. Logic problems for children- these are, as a rule, whole stories with popular actors, in which you just need to get used to, feel the situation, visualize it and grasp the connections.
Even the most difficult logic problems do not contain numbers, vectors, functions. But a mathematical way of thinking is necessary here: the main thing is to comprehend and understand the condition logical problem. The most obvious solution on the surface is not always the right one. But most often, solving a logic problem turns out to be much simpler than it seems at first glance, despite the confusing condition.
Interesting logic problems for children in a variety of subjects - mathematics, physics, biology - cause them increased interest in these academic disciplines and help in their meaningful study. Logic problems for weighing, transfusion, non-standard tasks logical thinking will help in Everyday life solve everyday problems in a non-standard way.
In the process of solving logic problems 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 his work “Analytics,” Aristotle created 20 patterns of reasoning, which he called syllogisms. One of his most famous syllogisms is: “Socrates is a man; all people are mortal; So Socrates is mortal." Logic (from ancient Greek. Λογική - speech, reasoning, thought) is the science of correct thinking, or, in other words, the “art of reasoning.”
There are certain techniques solving logical problems:
way of reasoning, with the help of which the simplest logic problems. This method is considered the most trivial. During 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.
table method, used in solving text logic problems. As the name suggests, solving logical problems involves constructing tables that allow you to visualize the conditions of the problem, control the reasoning process, and help you draw correct logical conclusions.
graph method consists of brute force possible options development of events and the final choice of the only correct decision.
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 a flowchart, which is essentially a program, the execution of which leads to the solution of the task.
billiards method follows from trajectory theory (one of the branches of probability theory). To solve the problem, you need to draw a billiard table and interpret the actions by the movements of the billiard ball along different trajectories. It is necessary to keep records 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 a wide variety logic problems for grades 1, 2, 3, 4, 5, 6, 7, 8, 9. We have selected for you the most interesting logic problems with answers, which will be of interest not only to children, but also to parents.
- choose for the child logic problems in accordance with his age and development
- take your time to reveal the answer, let the child find it himself logical solution tasks. Let him get there on his own the right decision and you will see what pleasure and feeling of delight he will have when his answer coincides with the given one.
- in progress solving logic problems Leading questions and indirect clues indicating the direction of reflection are acceptable.
Using our selection logic problems with answers you will really learn to solve logical problems, expand your horizons and significantly develop logical thinking. Go for it!!!
Solving logical problems - the first step towards child development.
E. Davydova
Logic is the art of arriving to an unpredictable conclusion.
Samuel Johnson
Without logic it is almost impossible to enter our world brilliant discoveries of intuition.
Kirill Fandeev
A person who thinks logically stands out nicely against the backdrop of the real world.
American saying
Logic is the morality of thought and speech.

In this article we will look at the most interesting puzzles intended for children, but not every adult can master them. They managed to stupefy more than one Internet user and gained enormous popularity on the Internet, as did comic tests with answers - but how quickly can you cope with them? The correct answers are waiting for you at the end of the article!
Where does the bus go?
If we talk about the most popular children's tasks on the Internet, this is one of them. Here is a picture of a bus. Which way is he heading?
How many points are there?
More attentiveness tasks for the most eagle-eyed users: how many black dots do you see at the intersections of lines?
Which circle is bigger?
Now let's solve interesting graphic puzzles. Can you answer which of the yellow circles shown in the picture is larger?
Moving the matches
The following children's puzzles are also often given to first-graders to solve: they require you to move matches in a certain way to get a given figure.
Find the panda!
The Internet was also blown up by the following graphic puzzles by artists who placed an image of a panda in complex pictures and invited other users to find it. They hid the panda in the crowd of stormtroopers from " Star Wars”, in a gathering of metalheads, and even tried to hide her among the myriad of massage tables. Check your attentiveness!
Japanese IQ test
But what kind of IQ test did the Japanese come up with? On the shore there is a man with two sons, a mother with two daughters and a policeman with a criminal. In front of them is a raft on which they need to get to the other side. Try to think about how they can be transported there, taking into account such interesting conditions:
- Only two people can fit on the raft at a time, and it cannot float without people at all.
- Children can only travel on the raft with an adult. But sons cannot remain alone with the girls’ mother, and daughters cannot remain alone with the boys’ father.
- And the criminal cannot be left alone with others without the supervision of a policeman.
Found the answer? If not, watch this interesting test in the video:
Right answers
There can be two correct answers to this puzzle. The first is that the bus goes to the left, since on the other side, invisible to the viewer, there are doors through which passengers get inside. This answer is valid for our roads with right-hand traffic. But for countries where traffic left-handed, the correct answer is right.
The picture shows parking spaces, and a car occupies one of them. If you turn the picture over, you will realize that you originally saw the numbers upside down. Therefore, the number under the car is 87. No matter how much you try to calculate some clever polynomial here, such interesting puzzles are not designed for algebraic logic, but rather for ingenuity.
Missing value = 2. To solve such children's puzzles, you need to put yourself in the shoes of the children. Do kids know how to solve complex equations and count arithmetic progressions? But they notice that the values in the columns depend on the number of circles in each set of numbers. Let's take, for example, the row 6855: in the number 6 there is one circle, and in the number 8 there are two, so the output is 1+2 =3, that is, 6855=3. And in row 2581 only the number 8 has two circles, so the solution is 2.
There are 12 points in total in the figure. But our brain is designed in such a way that it does not allow us to see them all at the same time, so at a time we can only notice three or four black dots.
The mugs are exactly the same! Such simple puzzles are built on visual illusion. The blue circles on the left side of the picture are large and some distance from the yellow one. The circles on the right side are small and stand close to the yellow circle, which is why it seems to us that it is larger than the first one.
Here's how to solve interesting children's puzzles with matches:
Unmasking the panda:
These tasks can be given to children on the way to school, while traveling, or you can arrange a competition for children's party. It’s rare that anyone will be able to answer the question right away, so you should gradually give small hints, this will make solving it more fun and interesting.
We hope that you don’t just put your child in front of the computer so that he can immediately look at all the answers. Don't forget that no car can replace your son or daughter parental love and attention.

80. Problem invented by the learned monk and mathematician from Ireland Alcuin (735–804).
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.

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..

272. A train leaves Moscow for Vladivostok every day. Also, every day a train leaves from Vladivostok to 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 ground on hot-air balloon or an 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 stationary, 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 the 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. Because the heat from 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. Suitable for boiling water cardboard box. 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.

Correct answer
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.
Correct answer

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).
Correct answer

Correct answer
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.
