142 pages. Step-by-step explanation: The provided parameters state that the first page of the lost portion of the book is numbered 143. The last page has the same digits as 143. As the book is divided into two segments, one segment begins at page one, while the other follows after the first segment ends. Therefore, the pages in the first section are numbered from 1 up to the first page of the second part minus one, which means the missing part of the book contains pages from 1 to 142, resulting in 142 pages.
