Answer 1

Answer:

HOPE IT HELPS YOU

Step-by-step explanation:

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 = 1179  

= 13 bundles     ( Ans )
