Problem Analysis

In the school library, 15 students came. Out of these, 7 students took 3 books each, and the remaining students returned their books. We need to find out how many books the students took from the library.

Solution

To solve this problem, we can calculate the total number of books taken by the students who borrowed books.

Let's break down the solution step by step:

1. Calculate the number of books taken by the 7 students who borrowed books: - Number of students who borrowed books: 7 - Number of books each student borrowed: 3 - Total books taken by the 7 students: 7 * 3 = 21

2. Calculate the number of books returned by the remaining students: - Total number of students: 15 - Number of students who borrowed books: 7 - Number of students who returned books: 15 - 7 = 8

3. Calculate the total number of books taken by the students: - Total books taken = Books taken by the borrowing students + Books returned by the remaining students - Total books taken = 21 + 0 (since the remaining students returned their books) = 21

Therefore, the students took a total of 21 books from the library.

Answer

The students took a total of 21 books from the library.
