In a library, 25% of the number of mathematics books is equal to two-third of the number of physics books. What is the ratio of the number of mathematics books to that of the physics books in the library?

Correct option is B

Given:
25% of the number of mathematics books = two-thirds of the number of physics books.

Solution:

​Let the mathematics books be M  and physics books be P

​$$\frac{25}{100} \times M = \frac{2}{3} \times P\\ \ \\\frac{M}{P} = \frac{8}{3}$$​​

M : P = 8 : 3
