Hehe, it's 480 pages. Suppose there are x pages in the whole book, then 1 / 2x-1 / 3x = 80, it's not difficult to find x = 480



A story book, Xiaoxiao read one third more than two pages of the whole book on the first day, one half less than one page on the second day, and there are still ten pages left
How many pages are there?


Let this book have X pages,
(1/3*x+2)+(1/2*x-1)+10=x
The solution is: x = 66
