We offer you to solve the puzzle about dogs, reports Rus.Media. It can be found in school textbooks. But I’ll tell you honestly, not every adult could cope with it. I hope you’re not among them.

The brain, like muscles, need to train to keep his mental tone. This job is perfect for stage to warm-up.

Math. Develops logical and analytical thinking and visual perception.

So. We have two different breeds of dogs and bones. With the latter you have to suffer the least. Each bone represents one number — one.

Need to find the answer: the number that should come in place of question mark in the fourth example. But you must deal with the three previous ones, with each separately.

Let’s start with the first one. Three Dinghy to a total of 15. They are absolutely identical. This means that each of them represents the same number. To learn it, you just need to divide fifteen by three.

In the second example, the Fido add two dogs named Scarlett. All of these animals together make up the number thirteen. As in the case of the bulldog, every Dalmatians also is the same number. To learn it, you need of the thirteen subtract the number that corresponds to the first dog (and you know it). And then the answer divided by two.

The number, which is encrypted Scarlett, you already know. But you can test yourself. If by adding six, as in the third example, as much seed, you’ll get back ten, you know that all your previous calculations were correct.

In the fourth example, instead of each animal use the corresponding number and get the answer. Feel like a connoisseur of “What? Where? When?” who successfully guessed the contents of the black box.

Probably you did it, maybe even without prompting. In return for this hold the right answers.

Fido is 5, Scarlett is 4 and a question mark — 14.
