Only the chosen ones will solve: a math puzzle that will show your IQ level

How confident are you that you remember your school arithmetic curriculum well? A puzzle will help you test your knowledge of this seemingly simple subject.

At first glance, there is nothing complicated in the picture published by OBOZ.UA. The only mathematical operation here is addition. But can you give the right answer in 9 seconds? Let's find out.

Experts say that doing such exercises regularly helps improve your problem-solving skills and trains your brain. But you have to fulfill one requirement: give the answer yourself, and then check it against the explanation and solution. So, set the timer for 9 seconds. If you don't make it within this time, it's okay - it's a champion result that you can be proud of, but not a prerequisite for passing the test. You can spend more time on it. Are you confident in your calculations? Then proceed to the explanation.

So, in the picture, we see equations with pictures of animals instead of numbers. We see three variants of unknowns: an owl, a mouse, and a puppy. You need to solve the first three equations to determine all the unknowns and find the sum in the last one.

So, in the first equation, we see that four owls equals 80. Let's replace the owl with X, and then the example can be written as 4X=80. This means that X is 80 divided by 4. So the owl here stands for the number 20.

Next, we see an example in which one owl and two mice total 30. Since we already know the "value" of the owl, let's substitute the mouse as Y in the equation. We get 2Y+20=30. Subtract the number we know from the sum and we get 2Y=10. We divide the result by 2 to find the "price" of the mouse and get 5.

All that remains to be calculated is the "cost" of the puppy. To do this, use the last equation with a known sum. It's the simplest because it has only two terms. We know what the mouse means, and we'll denote the puppy by the letter Z. Then the example can be written as follows: 5+Z=15. To find the answer, you just need to subtract 5 from 15. And it turns out that the puppy stands for the number 10.

All that remains is to substitute the found values into the last equation. It turns out that owl + puppy + mouse = X + Z + Y = 20 + 10 + 5 = 35. The correct answer to the puzzle is 35.
