A tricky problem that 90% of people answer wrong, you need to think hard.

At first glance, it seems like a very simple mystery. A lot of people will answer it, and it turns out to be untrue. Normal logic does not always come to the rescue. Sometimes, to solve an example, you need to carefully think and calculate everything. How to solve the problem The editorial staff will tell you right today. "Site". And you'll test yourself to see if your answer is correct.



Peels So, repeat the condition of the problem again. The brick weighs 1 kg and half a brick. How much does a brick weigh?

Our brain needs constant training. And this task is just a godsend for testing the brain's endurance. When solving this problem, not everyone will win. And this is not surprising, because we give the first answer without thinking. If it immediately occurred to you that the entire brick is 1.5 kg, then this is the wrong answer. What makes this task so difficult? Read on. How much does a brick actually weigh?



In everyday life, we do not have time to solve problems and puzzles. We are in a constant stream of information that requires our attention. Our brain is constantly working without respite. And he, like any other device, needs reboots. In such cases, we recommend that you sometimes do such small intellectual warm-ups. They will help to distract and rest, and then the brain will quickly find a solution in various situations.



In this problem, there is little to rely on logical thinking. Here you need to use your knowledge in mathematics. Remember how we were taught in high school to make simple equations. It’s not easy to remember what you learned years ago. But our memory is a unique organ, it remembers everything and at the right moment simply provides us with the right memories or knowledge. So to solve this problem, take a piece of paper and a pen. It is best to write down the equation so as not to score anything or lose sight of it.



To solve this problem, we need to write its condition in the form of a mathematical formula. Many people think it will look like 1 kg + 0.5 kg = 1.5 kg. 80% of people think that this is the right solution to this problem and are very wrong. Let’s see why this decision is wrong. In our task, the weight of the brick is unknown. And we're going to call it the usual X. Then we get the following equation: X = 1 kg + 0.5 X kg. The equation of 0.5X is nothing more than half the weight of a brick.



Now, remembering elementary school, move 0.5X to the left side of the equation, while not forgetting to change the sign from plus to minus. We get an equation of the following kind: X-0.5X=1. Here everything becomes quite simple and clear, and even a primary school student will cope with this equation. The next step is to take X-0.5X and get 0.5X. Then our equation looks like this: 0.5 X = 1. Now we leave X on the left side and we have 1/0.5 on the right. And so we have X=2.

And now we know that the weight of one brick is 2 kg. What answer did you get? Write in the comments your calculation options.
