Answer 1

Представим что на двух полках было по 10 книг. С верхней взяли 2,  значит уже 8 книг. И еще поставили 8, уже 16. А на нижнюю поставили еще 4, становится 14. Отнимаем 16 от 14 получаем 2 книги. Ответ: на 2 книги.

На 2 книги больше на верхней полке

Answer 3

Problem Analysis

We have two shelves with an equal number of books initially. From the top shelf, we take 2 books and place 8 books on top of them. On the bottom shelf, we place 4 books. We need to determine the difference in the number of books between the top and bottom shelves.

Solution

Let's assume that the initial number of books on each shelf is x.

After taking 2 books from the top shelf, there are x - 2 books remaining on the top shelf.

After placing 8 books on top of the 2 books, the total number of books on the top shelf becomes (x - 2) + 8 = x + 6.

On the bottom shelf, we place 4 books, so the total number of books on the bottom shelf becomes x + 4.

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

Difference = (x + 6) - (x + 4) = x + 6 - x - 4 = 2

Therefore, the difference in the number of books between the top and bottom shelves is 2.

Answer

The number of books on the top shelf is 2 more than the number of books on the bottom shelf.
