1. Following are the car parking charges near a railway station up to.
4 hours – ₹ 60

8 hours – ₹100

12 hours – ₹140

24 hours – ₹ 180

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

Checking if the given values are in direct proportion by seeing the ratios of time period and the parking time:
Since, we have, \(\frac{4}{60}\neq \frac{8}{100}\neq\frac{12}{140}\neq \frac{24}{180}\)

Therefore, the given charges are not in direct proportion to the parking time
