If 18 binders bind 900 books in 10 days how many binders will be required to bind 660 book in 12 days​

Answer 1

Answer:

11 Binders in 12 days will bind 600 books

Step-by-step explanation:

Binders              Day     Books

18                       10         900

18                       1            900/10 =90

1                         1             90/18 = 5

1                        12            12 x 5 = 60

for 60 Books in 12days you need 1 Binder

therefore  

for 660 Books you need 660/60 = 11 days

Asnwer : You need 11 Binders to bind 660 books in 12 days

Answer 2

Answer:

11 binders

Step-by-step explanation:

900books/10days=90books per day

660books/12days=55books per day

if 18 binders=90books per day

1 binders=55books per day

55*18/90 =11 binders.

hence 11 binders can bind 660 books in 12 days
