Problem Analysis

We are given the following information: - The first book has 139 pages. - The second book has 87 pages less than the first book. - The third book has the same number of pages as the first and second books combined.

We need to find the total number of pages in the three books.

Solution

Let's break down the problem step by step:

1. Find the number of pages in the second book. - The second book has 87 pages less than the first book. - So, the second book has 139 - 87 = 52 pages.

2. Find the number of pages in the third book. - The third book has the same number of pages as the first and second books combined. - So, the third book has 139 + 52 = 191 pages.

3. Find the total number of pages in the three books. - The total number of pages is the sum of the pages in the first, second, and third books. - So, the total number of pages is 139 + 52 + 191 = 382 pages.

Therefore, the three books have a total of 382 pages.
