My grandson at school was asked a logical problem, which almost boiled my brain Bashny.Net

Logical tasks for children Sometimes so confusing that even adult aunts and uncles are unable to find the key to the solution. And this is not surprising, because students constantly solve problems in a variety of subjects. While adults are mired in daily routine and even a small warm-up for the mind do not allow themselves.



And today's edition. "Site" Ask readers to solve several problems. Take a few minutes of your time to find the right answers. At the same time, you will see how easily and quickly you manage to cope with tasks on logic.

Logical tasks for children

1. To solve the first logical problem, you need to help the head of the guard to strengthen the security of the fortress. Moreover, the wall that surrounds the fortress is built in the form of a square. Also on each wall there is a gate, near which two soldiers are on duty. It turns out that the chief of the guard is subordinate to 8 soldiers. And he needs to organize everything so that each wall is guarded not by two soldiers, but by three. Is that possible?
   
   
   
   
2. She made five cupcakes for her daughter and her friends. The child came home with five friends. And now we need to figure out how to divide five cupcakes so that each of the six children gets an equal share. How to do this without cutting each cupcake into six pieces? After all, if you cut the cupcake into six parts, it will completely crumble.
   
   
   
   
3. In the ancient forest, tourists found three beautiful stones. Here they saw a sign stating that the total weight of the stones is 360 kg. The first stone is 2 times lighter than the second. The third stone is three times heavier than the first. Can tourists figure out how much each stone weighs?
   
   
   
   

Tips and solutions

1. First, place one soldier near each gate. Many readers will be able to guess what to do next. All that remains is to place the remaining four soldiers in the corners of our square to complete the task. Each wall is guarded by three soldiers.
   
   
   
   
2. It is enough to cut three cupcakes in half and give each child half. And then cut the remaining cupcakes into three pieces each to give the six guys another slice. Everyone is happy, no one is without sweets. Of course, except for the woman who made the cupcakes.
3. From the conditions we understand that the first stone is the lightest. We can take his weight for it. The second stone will weigh 2x and the third stone will weigh 3x. In this case + 2 + 3 = 360 kg. Then 6 = 360 kg, and = 360 ÷ 6 = 60 kg. Therefore, the second stone weighs 60 × 2 = 120 kg. The third stone weighs 60 × 3 = 180 kg.
