A book seller purchased 117 books out of which 45 books of mathematics and 72 books of physics.Each book has same size .Mathematics and Physics books are to be packed in bundles and each bundle must contain same no. of books.Find the least number of bundles which can be made for these 117 books.

I assume you mean each bundle contains only math or physics books.
GCD(45,72) = 9
So, each bundle has 9 books, making
5 bundles of math
8 bundles of physics
