How many questions are there in a book, if there are a total of 11 chapters in a book and each chapter contains 240 questions?
The total number of chapters in a book = 11 chapters
1 chapter = 240 questions
the total number of questions is-
240 × 11 = 2640
240 \times\ 11 = 2,640
So, a total of 2,640 questions are there in a book.
