Number of kids is 5 and number of adults is 3.

Step-by-step explanation:

  • Step 1: Let the number of adults be x. Then the number of kids is (8-x). Cost of tickets for adults = 6x

Ā  Ā  Ā  Ā Cost of tickets for kids = 3(8-x) = 24 - 3x

Ā  Ā  Ā  Ā Total cost = 33 = 6x + 24 - 3x = 3x + 24

ā‡’ 3x = 9

āˆ“ x = 3

ā‡’ 8 - x = 8 - 3 = 5

āˆ“ Number of kids is 5 and number of adults is 3.
