Analysis: the difference of the total number of people in the two queues is 24-4=20, and the difference of the number of people in each row is 9-8= 1 person, so the total number of rows is 20÷ 1=20, and the total number of people is 20× 9+4 =180.

Solution: (24-4)÷(9- 1)

=20÷ 1

=20 (line)

20×9+4= 184 (person)
