450 :300 : : 300 : x
450/300=300/x
x= 300×300/450=200
so., no of maths book= 200
450 :300 : : 300 : x
450/300=300/x
x= 300×300/450=200

Let the number of maths books be x.
Given that the ratio of science books to social books are same as the ratio of social studies books to maths book. 450 books in science and 300 in social.
= > 450 : 300 :: 450 : x
= > (450/300) = (450/x)
= > 450x = 300 * 450
= > 450x = 135000
= > x = 300.
Therefore the number of maths books = 300.
Hope this helps!
