If you read a book, you can read a quarter of the book on the first day, and two-fifths of the book on the second day. There are still 14 pages left. How many pages are there in this book?
Suppose the book has x pages. On the first day, he read a quarter of the book, which was 1/4 * x page of the book. The next day, he read two-fifths of the book, which was 1/4 * x pages, 2/5 = 5/16 * x pages. There were still 14 pages left, so: 14 ÷ (5/16 * x - 1/4 * x) = 14/(1/4 * x - 1/4 * x) = 14/(1/16 * x - 1/16 * x) = 14/(5/8 * x) = 14/(1/8 * x) To simplify it: 14/(1/8 * x) = 14 So 8 * 14 = x Solution:x = 96 So this book had a total of 96 pages.
