Given:
The ratio of the number of fiction books to the number of non-fiction books in a library is 5:2.
Total number of books = 1421
To find:
The number of books of each type.
Solution:
Let the number of fiction books be 5x and number of non-fiction books be 2x.
Total number of books = 1421
Now,
Number of fiction books :![5(203)=1015](/tpl/images/0880/2481/1797e.png)
Number of non-fiction books :![2(203)=406](/tpl/images/0880/2481/c6914.png)
Therefore, the number of fiction and non-fiction books are 1015 and 406 respectively.
