Title: A bookstore has a new batch of bulk books. If you bind 36 books every day, you can complete the binding in 6 days. Because the skilled workers are here, the daily work efficiency is 1.5 times that of the original plan to bind books every day. Q (1) How many books are actually bound every day? (2) How many days did it actually take to bind all the books? (3) How many days ahead of schedule?

Solution: (1) Books bound every day: 36 * 1.5 = 54.

(2) The actual binding time is: 36 books/day * 6 days /54 books/day = 4 days.

(3) Lead time: 6 days -4 days = 2 days.
