Question

Following are the car parking charges near a railway station up to

4 hours Rs 60

8 hours Rs 100

12 hours Rs 140

24 hours Rs 180

Check if the parking charges are in direct proportion to the parking time.

Solution

A table of the given information is formed as

Number of hours 4 8 12 24
Parking charges (in Rs) 60 100 140 180 

The ratio of parking charges to the respective number of hours (Rs/ hour) can be calculated as

`60/4 = 15, 100/8 = 25/2, 140/12 = 35/3, 180/24 = 15/2`

As each ratio is not same, therefore, the parking charges are not in a direct proportion to the parking time.
