Question

Following are the car parking charges near a railway station up to Check if the parking charges are in direct proportion to the parking time.

Answer 1

for 4 hrs: `60/4 = 15`
for 8 hrs: `100/8 = 12.5`
for 12 hrs: `140/12= 70/6`
for 24 hrs: `180/24 = 7.5`
as we can see, the proportions are unequal
so parking charges are not in direct proportions to the parking time
