A book has a total of 200 pages, and 120 pages have been read. The percentage of the book can be calculated by calculating the ratio of the number of pages in the book to the number of pages that have been read. The total number of pages in the book is 200, and the number of pages that have been seen is 120. Therefore, the ratio of the number of pages that have been seen to the number of pages in the book can be calculated as: 120 ÷ 200 × 100% ≈ 625% Therefore, he had read about 625% of the book.
