Answer 2

Answer:

THIS IS UNITARY METHOD. WE HAVE TO FIND THE WEIGHT OF 1 BOOK FIRST AND THEN THE WEIGHT IS MULTIPLIED WITH NO. OF BOOKS WE HAVE TO FIND.

57 books weigh 11kg 400gm

then, 1 book  = 11400gm / 57

                          = 200gm

Therefore, 71 books = 200 * 71

                                   = 14200gm

14200 gm = 14kg 200 gm
