Answer :
Since, the bookseller sold 1000 books, let us consider that the bookseller sold x no. of books at Rs 24 each and (1000 - x) no. of books at Rs 22.50
Then,
total receipt = Rs 23670
⇒ 24x + (1000 - x)×(22.50) = 23670
⇒ 24x + 22500 - 22.50x = 23670
⇒ (24 - 22.50)x = 23670 - 22500
⇒ 1.5x = 1170
⇒ x = 780
Therefore, the bookseller sold 780 books at Rs 24 each and (1000 - 780) = 220 books at Rs 22.50 each.
