Problem Analysis

The problem states that a librarian has arranged books in a shelf with 8 shelves, and the last 2 shelves are empty. Each shelf can hold 25 books. We need to determine the total number of books arranged by the librarian.

Solution

To find the total number of books arranged by the librarian, we need to calculate the number of books on the non-empty shelves.

Since each shelf can hold 25 books, the number of books on the non-empty shelves is given by: ``` Number of books on non-empty shelves = Number of shelves * Number of books per shelf ```

Substituting the given values: ``` Number of books on non-empty shelves = 8 * 25 ```

Calculating the result: ``` Number of books on non-empty shelves = 200 ```

Therefore, the librarian has arranged a total of 200 books.

Answer

The librarian has arranged a total of 200 books in the shelf, considering that there are 8 shelves and the last 2 shelves are empty.
