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.

Answer :

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
