Problem Analysis

We are given that there were an equal number of books on two shelves. On the top shelf, 2 books were initially taken, and then 8 books were placed on top of them. On the bottom shelf, 4 books were placed. We need to determine how many more books are on the top shelf compared to the bottom shelf.

Solution

Let's calculate the number of books on each shelf step by step:

1. Initially, there were an equal number of books on both shelves. 2. Two books were taken from the top shelf, so the number of books on the top shelf decreased by 2. 3. Eight books were placed on top of the remaining books on the top shelf. 4. Four books were placed on the bottom shelf.

To find the difference in the number of books between the top and bottom shelves, we need to subtract the number of books on the bottom shelf from the number of books on the top shelf.

Let's calculate the number of books on each shelf:

- Top shelf: Initially equal, then 2 books were taken, and 8 books were added on top. So, the number of books on the top shelf is 2 + 8 = 10. - Bottom shelf: Initially equal, then 4 books were added. So, the number of books on the bottom shelf is 4.

To find the difference, we subtract the number of books on the bottom shelf from the number of books on the top shelf:

10 - 4 = 6

Therefore, there are 6 more books on the top shelf than on the bottom shelf.

Answer

There are 6 more books on the top shelf than on the bottom shelf.
