Problem Statement

В школьной библиотеке на трех полках лежит 285 книг. На первой полке 109 книг, на второй на 32 книги больше, а на третьей полке остальные книги. Сколько книг на третьей полке?

Solution

Let's solve the problem step by step.

1. We know that there are a total of 285 books on the three shelves. 2. On the first shelf, there are 109 books. 3. On the second shelf, there are 32 more books than on the first shelf. 4. The remaining books are on the third shelf.

To find the number of books on the third shelf, we can subtract the number of books on the first and second shelves from the total number of books.

Let's calculate the number of books on the third shelf:

Total number of books = 285 Number of books on the first shelf = 109 Number of books on the second shelf = Number of books on the first shelf + 32

Now, let's substitute the values and calculate the number of books on the third shelf:

Number of books on the second shelf = 109 + 32 = 141

Number of books on the third shelf = Total number of books - Number of books on the first shelf - Number of books on the second shelf

Number of books on the third shelf = 285 - 109 - 141

Number of books on the third shelf = 35

Therefore, there are 35 books on the third shelf.
