Let the total number of books in the library be x
50% of total number of books is of Marathi.
Number of Marathi books = 50% of x
= (50/100)x
= x/2
The books of English are (1/3) of Marathi books.
Number of books of English = (1/3) x (x/2)
= x/6
The books on Mathematics are 25% of the English books.
Number of books of Mathematics
= 25% of x/6
= (25/100) x (x/6)
= x/24
Since, there are 560 books of other subjects, the total number of books in the library are
∴ 24x – 17x = 17x + 13440 – 17x
∴ 7x = 13440
∴ x = 1920
∴ The total number of books in the library are 1920.
