Problem Analysis

We are given that there are 44 books arranged on three shelves. The number of books on the top shelf is twice the number on the bottom shelf, and the number of books on the middle shelf is four times the number on the top shelf. We need to determine the number of books on each shelf.

Solution

Let's assume the number of books on the bottom shelf is x. According to the given information: - The number of books on the top shelf is twice the number on the bottom shelf, so it is 2x. - The number of books on the middle shelf is four times the number on the top shelf, so it is 4(2x) = 8x.

We know that the total number of books is 44, so we can write the equation: x + 2x + 8x = 44

Simplifying the equation: 11x = 44

Dividing both sides by 11: x = 4

Therefore, there are 4 books on the bottom shelf, 2x = 2(4) = 8 books on the top shelf, and 8x = 8(4) = 32 books on the middle shelf.

Answer

There are 4 books on the bottom shelf, 8 books on the top shelf, and 32 books on the middle shelf.
