We say that x and y are in direct proportion, if   or

Hence in the given problem we have,

Charges for the parking :

 y x 4 hours Rs. 60 8 hours Rs. 100 12 hours Rs. 140 24 hours Rs. 180

considering x to be charged to be paid and to be the parking time.

Then we calculate  ,

For:-    4 hours:                       8 hours :

12 hours :                  24 hours:

Clearly  is not equal to some constant 'k',  then we can say that
