Step-by-step explanation:

a library has books for primary classes,middle classes and higher classes. 5/9 of all the books in the library are for primary classes and 2/15 of all the are for middle classes. if there are 7294 books for higher classes.

Let say total books 45T

Primary class books = (5/9)45T = 25T

Middle class books = (2/15)45T = 6T

Higher class books = 45T -25T -6T

= 14T

14T = 7294

T = 521

Primary class books = 25 * 521 = 13025

Middle class books = 6*521 = 3126
