Mathematical problems and tasks

1. The egg problem
   I had 6 eggs. I broke two eggs, fryed two and ate two. How many eggs are left after that?
   
   
2. Find logic.
   What is the logic behind the numbers? Try to figure it out.
   
   
   
   15 * 15 = 9
   26 * 26 = 19
   37 * 37 =?
   
   
3. Fill the empty cell.
   In this task, you only need to fill one cell. However, the obvious solution in the form of a six is not suitable. Can you guess what this is about?
   
   
   
4. How do I open the lock?
   Guess the code to the lock using the conditions indicated in the picture. You only need 3 digits, but finding them is not easy. You will have to think carefully to see which combination will work. Can you handle it?
   
   
   
5. How to measure 1 liter of kvass?
   Imagine you have a whole barrel of kvass. In addition, there are two empty bottles of 3 and 5 liters. How to use these bottles to measure exactly one liter of kvass?

1. Well, you don't have to be Gregory Perelman to recognize a catch. It is logical to assume that the author fried the same eggs that he broke. Because frying eggs without breaking them, it's pretty hard. In addition, it can be concluded that he also ate probably not raw eggs. So, 2 eggs were broken, they were cooked, they were eaten. Stays. 4 eggs.
   
   
2. First, write down the correct answers. 15 * 15 = 225
   26 * 26 = 676
   37 * 37 = 1369
   
   How do you get 9 out of 225? Consistently adding up all his numbers! Using this method, we get the following.
   
   225 -> 2 + 2 + 5 = 9
   676 -> 6 + 7 + 6 = 19
   1369 -> 1 + 3 + 6 + 9 = 19
   
   Number sought: 19.
   
   
3. 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 lettering!
   
   
   

First look at the first line 6, 8, 2. What's the right number here and there? The fourth line says there is no 7, no 3, no 8 in the code. So the first line is either 6 or 2. However, under the terms of the second line, the number 6 can also be dropped. It becomes clear that the code looks like XX2, where XX is the numbers that still need to be found. From the penultimate and final conditions, we understand that the code has the number 0. From the third condition, we find that 0 is not in second place. That's right. The code takes the form of 0X2. And from the second and third conditions, we understand that X is the number 6. Because code 062.

First, fill to the brim a bottle of 3 liters. Then pour everything from a three-liter bottle into a five-liter bottle. Then again pour kvass into a three-liter bottle from the barrel. It remains to pour kvass into a five-liter bottle before filling. Voila, in the three-liter bottle remained exactly 1 liter of kvass.

We hope that solving these problems gave you pleasure. Write down which problem was the most difficult and which problems were solved without much effort.
