A bookseller purchased 117 books out of which 45 books are of maths and remaining books remaining 72 books are of physics is book has same size maths and physics books are to be packed in separate bundles and his mandal must contain same number of books find the least number of bundles which can be made

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 = 1179 
= 13 bundles     ( Ans )

Answer 2

Answer:

Bookseller purchased 117 books out of which

Mathematics books= 45 and

Physics books = 75 

H.C.F of 45 and 72 is

72 = 2*2*2*3*3

45 = 5*3*3

So H.C.F is 9 ,

So total no. of  books in one bundle=9  

Total number of books = 117

So total bundle form by these books of same size = 1179 

                                                                                   = 13 bundles    

                                                                                                         (Ans)
