Answer:
In the library there are in total 800 books.
Step-by-step explanation:
The number of non fiction books = 3 for every 7 fiction books.
⇒Ratio of Non Fiction : Fiction books = 3 : 7
Now, The total Non fiction books in library = 240
Let the total number of fiction books in the library = m
⇒Ratio of Non Fiction : Fiction books in Library = 240 : m
Now, By THE RATIO OF PROPORTIONALITY:
or,
⇒ m = 560
or, the number of fiction books in library = 560
So,the total number of books in library
= Fiction books + Non - fiction books
= 560 + 240 = 800
Hence, in the library there are in total 800 books.
