[A] 8 days
[C] 15 days
[B] 13 days
[D] 12 days

• 6 workers can bind 1500 books in 40 hr
  6 workers can bind 1 book in 40/1500 hr
  1 worker can bind 1 book in 240/1500 hr=4/25 hr
  4 worker can bind 1 book in 1/25hr
  4 worker can bind 1600 book in 1600/25 hr= 64hr
  since 4 worker works only 8 hrs in a day so it take total 8 day
