Answer:

60 books occupy 1.5m of shelf

∴, 1 book occupies (1.5/60) m of shelf

∴, 200 books occupy {(1.5/60)×200} m of shelf

=(1.5/6)×20

=30/6

=5m of shelf Ans.

now, 5m=500cm is occupied by 200 books

∴, 1cm is occupied by (200/500) books

∴, 80cm is occupied by (200/500)×80 books

=(2/5)×80

=2×16

=32 books Ans.
