Answer: 30 days
Step-by-step explanation:No.of pages a girl can read in 1day= 9pages
After 50 days she completes reading the book
No.of pages in the book= 50×9=450 pages
Second part:
If the no.of pages she reads in a day= 15 pages
No.of pages of the book= 450
Therefore, no.of days she will take to complete the book=450÷15=30 days
