No matter how many correct answers you get, this is not an IQ test. It is important to force your brain to think outside of the ordinary. Below we will give you some tips that will help tune your brain to the right wave and prevent it from aging.

brain exercises

Let a crossword, puzzle, sudoku, or any other similar thing that interests you always be in a conspicuous place. Every morning spend a few minutes on them, activate the brain.

Constantly attend exhibitions or conferences on topics unfamiliar to you. Think about how you can apply what you've learned to your industry.

How do you feel about taking a break from the gray routine for a few minutes and stretching your brain a little? Then choose any interesting logic question from this article and try to find the answer to it yourself. Just be careful not to peep into the answers right away - this is not only dishonest, but also uninteresting!

Mental workout for toddlers

Many of these mysteries have been well known since Soviet times, but still do not lose their relevance. The answers to them are so simple and obvious that it is almost impossible to guess right away. Ready? Then full speed ahead!

1. “Why do you go to bed when you want to sleep?” The whole "chip" of this question lies precisely in the wording. After all, if you say it out loud, the brain immediately perceives the first two words as one. Why? Well, how is this "why"? You can lie down on the bed, cover yourself with a blanket, close your eyes and ... And, by the way, the correct answer is "On the floor."

2. "When can a person be in a room without a head?" Another logic question with an elementary answer. However, it can be very difficult for a child to reach the right decision, because not even every adult can immediately guess what happens when we stick our head out the window.

3. "Can an ostrich call itself a bird?" You may be surprised, but no special knowledge from the field of zoology is needed in order to correctly answer this question, because even the most educated and erudite ostrich will not be able to name himself in any way. At least because he can't speak.

4. “Which words have a hundred consonants?” And here the child will undoubtedly become thoughtful. After all, it is difficult to even imagine such a word - as many as 100 consonants, and if you add vowels as well? What kind of lexical monster is this? But the correct answer, as always, lies on the surface - “STOL”, “STOP”, “STOP”, “STOP”, “STOP”.

5. “In front of you is a bathtub filled with water. On the edge lies a mug and a spoon. What should be used to quickly remove all the water from the bath? Think it's a mug? Because she's bigger? But a rational person, looking at your torment, will silently come up and pull out the cork.

6. “Three little pigs were walking through the forest. One walked ahead of the two, one behind them all, and one between the two. How did they go? To be honest, even adults often cannot answer such questions of logic with a catch. In fact, the pigs in this riddle are just following each other.

7. “The bull plowed the field all day. How many footprints did he eventually leave on the arable land? In fact, the bull leaves no traces at all, because the plow that he pulls behind him erases them.

8. “At 12 o'clock in the morning there is a torrential downpour. Could it be that after 72 hours there will be warm, sunny weather? No theory of probability will help you here, relax. But knowing how many hours in a day will help - there can be no sunny weather. If only because after the indicated 72 hours it will be midnight again.

So, we have considered some curious logic questions for children. And now let's move on to other, more complex and interesting tasks.

Other logic puzzles

We bring to your attention other interesting questions on logic that can make you think not only for kids, but also for their parents.

Wordplay

• “On the seashore lay a stone, on the surface of which a word of 8 letters was scratched. When the rich read this word, they began to cry, the poor, on the contrary, rejoiced, and couples in love parted. What was that word? We will not comment on the answer in any way, because everything will become clear by itself. And the word was - "Temporarily."
• “What word has 3 letters “l” and 3 letters “p” at once? - "Parallelepiped".

For math connoisseurs

• “How much earth is in a hole 3 meters in diameter and 5 meters deep?” Still trying to calculate and look for the density of different soil types? Don't forget that this is a question of logic. Already by the fact of its existence, the pit is empty, otherwise it would not be a pit.
• "How many times can you subtract 6 from 30?" Don't share, take away! Only one, because next time you will subtract 6 not from 30, but from 24.

Vital

• “Two friends were walking around the city and suddenly stopped, starting to argue. One began to assert that "this is red." Another objected to him and said that "this is black." The first was not at a loss and asked: "Why, then, is she white?", To which he heard: "Yes, because she is green." What were they talking about?" The correct answer to this riddle is currant.
• “Three centuries ago, this procedure was carried out at a distance of 50 meters. Now this distance has been reduced by 10 times, and all thanks to the invention of a Soviet scientist, which you have probably seen more than once. What is it?" Nothing comes to mind? In fact, we are talking about a table for checking eyesight, also known as

American scientists, who came across this picture and questions to it, considered that this is one of the most effective IQ tests in the history of mankind. Take a close look at the image, and then try to give the correct answer to just 9 questions.

Questions

1. How many tourists stayed at this camp?
2. How long ago did they come here: today or a few days ago?
3. How far is the camp from the nearest settlement?
4. How did the tourists get here?
5. What time of day is it now?
6. Where does the wind blow: from the south or from the north?
7. Where did Shura go?
8. Give the name of the person who was on duty yesterday.
9. What is the date and what month?

Right answers

Breaking your head? Well, time to reveal the cards and demonstrate how elementary the answers are to even the most difficult logic questions:

1. Four. To understand this, just look at the list of attendants (it has four lines), as well as the number of plates and spoons on the mat.
2. Not today, because between the tree and the tent, a nimble spider managed to weave a cobweb.
3. It is unlikely, because the guys were able to bring a live chicken with them (or she ran into them by accident, which, however, does not change the essence).
4. On the boat. Near the tree you can see a couple of oars, and since there were not very many cars in Soviet times, this is the most logical answer.
5. Morning, because the shadow falls to the west, and therefore the sun shines from the east.
6. This question on logic really requires additional knowledge. For example, you need to remember that on the south side of the tree the branches are always longer than on the north. Next you need to look at the fire - it deviates slightly towards the north, which means that the wind blows from the south.
7. Shura went to catch butterflies - from behind the bushes you can see a net falling on a winged beauty.
8. As you can see, Shura went for butterflies, and the boy sitting near the backpack with the letter "K" is Kolya. That is, two options already disappear. Another boy is engaged in photographing the surrounding nature. He also cannot be on duty. But what is his name? Looking closely, you can see that in the backpack with the letter "B" is a tripod - an indispensable attribute of the photographer. We conclude that the name of the photographer begins with the same letter, which means that Vasya is photographing. By the method of elimination, we find out that Petya is on duty today, and from here we come to the conclusion that Kolya was on duty yesterday.
9. The answer to this question is closely related to the previous one. So, Petya is on duty today. Near his name, the number 8 is written on the board - the 8th number. As for the month, the very situation in the picture suggests that it takes place in August - only then watermelons appear in our latitudes. Of course, there are also in September. But it can be quite difficult to find butterflies in early autumn, and the first fallen leaves appear on the ground.

Interesting? Did you know that only 6% of people can answer all 9 questions correctly? If you succeeded, you can accept congratulations, because this means that your IQ is 130 or more.
