In the school's library, there are 2300 different books. 80% of all the books are in English, but only 60% of these books were published in the country. How many English-language books have been published outside the country? Let's answer step by step:
There are 80 / 100 * 2300 = 1840 books in English at the library. Out of these books, only 60 / 100 * 1840 = 1104 were published inside the country. So there are 1840 - 1104 = 736 books in English published outside of the country. The answer: 736.
