I start the morning with solving logical problems, invigorate coffee, activate the brain for the whole day.

Every day in our personal lives or at work, we face a series of big and small problems. We can even say that our whole life is a continuous solution. And to deal with them without the ability to correctly, logically reason would be very difficult. Therefore, logical problems that develop thinking are so important. They teach us to notice patterns, to build chains of reasoning, to draw conclusions. In addition, tasks will be a pleasant addition to your leisure.

1. Coffee with milk
   Should you add milk to your fragrant and invigorating coffee? The opinions of experts on this matter differ. But Anne, as we can see, has already made her choice. And we just have to figure out what she drinks: coffee with milk or milk with coffee.
   
   
   
   GettyImages Let's start simple and deal with coffee. Initially, the cup was full of coffee, but eventually it was empty. She has never had coffee in her cup. Regardless of the size, she drank only one cup of coffee.
   
   
   
   
   
   It remains to be seen how much milk was consumed. And it's much easier to make it, knowing that Anne has completely drunk everything she poured. So, first she added half a cup of milk and then another half cup. It turns out that all Anne drank a cup of milk. So, both coffee and milk were drunk equally: exactly one cup.
   
   
2. Two coils of rope
   For smart people who easily solve such tasks, recruiters of IT corporations chase in the sweat of their faces. After all, finding graduates with high scores in the labor market is not a problem.

   To solve the intricate problem with ropes, you will have to work well with a lighter. Judge for yourself: it will be necessary to burn the first rope at two ends and at the same time the second, but already from one. It is logical to assume that after 30 minutes the first rope will burn completely. Then the second should remain a 30-minute period. You set it on fire at both ends and you get another 15 minutes.
