Explanation:

  Blue Sky International Airport handles passenger to cargo traffic in a ratio of 8 to 5.

  Number of cargo planes landed yesterday = 45

  Number of passenger planes landed = x  Number of cargo planes landed.

 Number of passenger planes landed yesterday = x 45

                                                                               = 8 x 9

                                                                               = 72 passenger planes.

 So a total of 72 passenger planes came in yesterday.
