Answer 1

Answer:

The book should have 320 pages

Step-by-step explanation:

Given there are 240 pages in a book each page contain 40 lines.

Total number of lines=pages*no of lines for each page

                                  =240*40

                                  =9600

If number of pages=30

No.of  pages=total lines/No.of lines in each page

                     =9600/30

                      =320

It requires 320 pages
