I take a book from a library containing 378 pages to be returned in a week's time. If I can read 14 pages an hour for three hours daily, for how long should it be renewed so that the book can be fully read?
4 pages per hour .
He will read 14×3=42 pages in 3 hour.
So,he will take(378/42)=9 days to complete the book .
So, he needs(9-7)=2 days more to renew .
D is correct choice.
