The mathematical and viral challenge that almost no one can solve

This seems to be a simple account, an accessible challenge to solve in seconds and send us the piece. But no. There is an enclosed cat – or rather details – that make this equation more complicated than it seems.

They say that it appeared in China, but quickly became viral around the world. Do you dare to play? Here is the picture we need to solve. The "numbers" are slippers, a trainer and a whistle. Do you know the answer?

The first thing that many calculate is the value of each object. But even with these numbers, there are different theories. For some, the answer is 30. For others 25. And there are those who play with a 20. Has anyone got it? NO!

First and foremost the most important. The values ​​of each object. The shoes are worth 10, Coach 5 and Whistle 4. These numbers are good.

Then there is another confusion, the most basic mathematics. The 10 shoes must be added to the 15 cars (5) and the whistle (4). 10 + 20 = 30. Is the answer correct? No

As we have said from the beginning, the important thing is the details.

First clue? There is only one shoe in the last equation.

The second index is more subtle: the DT does not have a whistle on the neck, which changes the numbers.

With this key data, the account changes. The shoe is worth 5 and it is necessary to add 4 (coach 5 – 4 of the whistle = 1. And 1 x 4 of the whistle = 4). The correct answer is 9.

Were they right?
