Question 1

Q1) Followings are the car parking charges near a railway station Opto

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

Solution:

Charges per hour.

^C1=\frac{60}{4}=\ Rs.\ 15

^C2=\frac{100}{8}=\ Rs.\ 12.50

^C3=\frac{140}{12}=\ Rs.\ 11.67

^C4=\ \frac{180}{4}=\ Rs.\ 7.50

Here, the charges per hour are not same.

i.e ^C1\ne^C2\ne^C3\ne^C4

Therefore, the parking charges are not in direct proportions to the parking time.
