Answer 1

Answer:
Bookseller purchased 117 books out of which 45 books of mathematics and 72 books of physics
For find how much books contains in one bundle , We find H.C.F of 45 and 72 As
apply Euclid's division lemma , we get
72 = 45 * 1 + 27
45 = 27 * 1 + 18
18 = 9 * 2 + 0

So H.C.F. of 45 and 72 is 9 , that's the number books in one bundle , total number of books = 117

So total bundle form by these books of same size = $\frac{117}{9}$
= 13 bundles ( Ans )
