Answer:
609
Step-by-step explanation:
Let the ratio be 5x : 2x.
Difference = 5x - 2x = 3x
According to Question,
5x + 2x = 1421
7x = 1421
x = 203
Difference = 3 × 203 = 609
Hence, there are 609 more mathematics books than science books in the library.

Answer:
There are 609 more mathematics books than science books.
Step-by-step explanation:
Let no of books of Mathematics be 5x. (according to ratio)
Books of science = 2x.
Total books = 5x + 2x = 7x
7x = 1421 (given)
x = 203 books
Books of mathematics = 5x = 5 * 203 = 1015 books
Books of science = 2x = 2 * 203 = 406 books
Difference of books = 1015 - 406 = 609 books
