Xinhua Bookstore sent a batch of books, which sold 25% on the first day, 45% on the second day and 500 copies on the first day.
640÷32%×45%—640
=2000×45%—640
=900—640

Ask for this batch of books first: 640÷32%=2000 (copies).
Then calculate the sales volume of the next day: 2000×45%=900 (Ben)
The second day sold more than the first day: 900-640 = 260 (Ben)
