The printing factory plans to bind a batch of 300 books every day, which will be completed in 15 days due to the urgent need for books to be listed. The number of albums is 0.2 times that of 65438+ plan.
Ask the total number of books to be bound first: 15 days *300 books/day =4500 books.
How many books are actually bound every day? 300 books/day * 1.2=360 books/day.
Finally, the total number of books is compared with the number of books bound every day: 4500/360/ day = 12.5 days.
