A savvy task to remember a math teacher with an unevil, quiet word

Human intelligence will help to find a way out of any situation. But many believe that a person can be intelligent only from birth, and it is impossible to acquire this quality. Is that really true?

We're in the newsroom. "Site" You can become more intelligent if you systematically develop your brain. We regularly look for curious people. clevernessWhich can put anyone at a loss. Though smart people will probably find the solution quickly. Test yourself?



Tasks to be smart

1. To solve the first problem, we suggest considering the simplest examples in the picture to immediately figure out what the solution path is. You have to figure out what numbers are hiding behind each image and what value should be in place of the question mark at the bottom.

2. The second task will be a trick problem. We only know that 5 cars in 5 minutes can produce 5 T-shirts. Given this performance, we need to figure out how long it will take to produce 100 of the same garments for 100 machines.

3. Next, we propose a more difficult task. Here you will have to find out what numbers are hidden behind cute black cats, white mice and pieces of cheese. You will have to show not only intelligence, but also attentiveness.

4. And finally, let's leave a problem where you just need to fill one cell. However, clear-cut A six doesn't fit here. Can you guess what this is about?
   
   
   
   

Problem-solving

1. Behind a pair of sneakers is 30/3 = 10. From here you can find the number that hides behind the image of a man (20 – 10) / 2 = 5. Then behind a pair of bandages lies (13 - 5) = 8. And behind one bandage is 4. Now let's solve the last example. There's only one sneaker and one bandage. However, special attention should be paid to a man who both shoes and holds one bandage in each hand. So the man here replaces 5 + 10 + 8 = 23. The last example is 5 + (23 * 4) = 5 + 92 = 97.
   
   
   
   
   
   
2. If 5 cars produce 5 T-shirts in 5 minutes, then 1 machine takes 5 minutes to produce one T-shirt. And if we have 100 cars, then 5 minutes is enough for 100 T-shirts.
3. To find out what value is hidden behind the black cat, you need to find the root of the square number (38 – 2) = 36. He'll be 6. The value hidden behind the mouse will already equal the square root of 150/6 = 25. Which means 5. In this case, behind 4 pieces of cheese is hidden 180/6/5 = 30/5 = 6. Behind 2 pieces, then 3 hides. Therefore, the last example takes the following form (6 * 2) - (5 * 3) = 12 - 15 = - 3.
   
   
4. This picture is not an ordinary numerical problem. What we see in the picture is a diagram of the car's gearbox. Therefore, in an empty cage should show off the beech R.
   
   
   
   

We hope that solving these problems gave you pleasure. Write down which task was the hardest and which one was the hardest. cleverness They were solved by you without much effort.
