Pile Y has the greater mean number of pages per book because it is 5 books less than pile W.

<h3>How to calculate greater mean number of pages?</h3>

From the complete information, we can deduce that the number of each pile of book is given as follows:

<u>For pile W;</u>

Red books = 10 × 5 = 50 red books.

Blue books = 5 × 5 = 25 blue books.

Therefore, total books in pile W = 50 + 25 = 75 books.

Mathematically, the mean for each pile can be calculated by using the following formula:

Mean = [F(x)]/n

Mean = 75/10

Mean = 7.5.

<u>For pile Y;</u>

Red books = 10 × 5 = 50 red books.

Mean = [F(x)]/n

Mean = 50/5

Mean = 10.

In conclusion, pile Y has the greater mean number of pages per book because it is 5 books less than pile W.
