How to solve the problem: how many saucers of the basket, if only 40 mushrooms in the basket

Mathematics tasks are easily solved if you understand the principle of solution. In this article you will find an affordable explanation of the simplest task.

Mathematics is a complex subject. To solve the problem, you need to know the formulas. But sometimes it is enough to think logically and the solution comes by itself. Below we will consider solving the simplest problem about mushrooms.

How to solve the problem - in the basket there are 40 mushrooms: of which 17 have at least one red and 25 mushrooms have at least one rush?

Question of the problem: How many mushrooms are in a basket?

We decide like this:

Of the 17 mushrooms, there are at least 1 red. Now we will find how many loads in the basket can be: 17-1 \u003d 16-so many or less loads.
Now we will find how many saucers can be: 40-16 \u003d 24-so many saucers or less.
Of the 25 mushrooms lies at least 1 rush, which means the number of mushrooms-redfish: 25-1 \u003d 24-so many saucers or more.
As a result, we know that the number of mushrooms-redfish mushrooms is 24 or less, and at the same time there can be less than 24 or the same. It follows that the number of saucers is 24.

Answer: Mushrooms-redfish in the basket is 24.
