Answer 2

Answer: 1,89,000 books

Step-by-step explanation:

Given:

50% of books are in Hindi

40% of books are in Telugu

50+40 = 100 - 90 = 10% of books are in Marathi

To find: Total number of books in library

i.e. 18900 books = Remaining 10% of books

Let the total number of books in library = X

$\frac{10}{100} * X = 18900$

$X = 18900 * 100/10$

$X = 18900 * 10 \\X = 1,89,000$

Therefore, total number of books in library are 1,89,000
