Calculation of Total Number of Books in the Library

To calculate the total number of books in the library, we need to use the given information about the percentage of books in different languages.

According to the information provided: - English books make up 36% of all books in foreign languages. - French books make up 75% of the English books. - The remaining 185 books are in German.

Let's calculate the total number of books in the library step by step:

1. Calculate the number of English books: - English books make up 36% of all books in foreign languages. - Let's assume the total number of books in foreign languages is represented by "x". - The number of English books can be calculated as 36% of "x". - Number of English books = 36/100 * x = 0.36x.

2. Calculate the number of French books: - French books make up 75% of the English books. - The number of French books can be calculated as 75% of the number of English books. - Number of French books = 75/100 * (0.36x) = 0.27x.

3. Calculate the total number of books: - The total number of books in the library can be calculated by adding the number of English books, French books, and the remaining German books. - Total number of books = Number of English books + Number of French books + Number of German books. - Total number of books = 0.36x + 0.27x + 185.

Therefore, the total number of books in the library is 0.36x + 0.27x + 185.

Please note that we don't have the exact value of "x" or the total number of books in foreign languages. Without that information, we cannot determine the exact total number of books in the library.
