Question

Question 01.
Following are the car parking charges near a railway station up to:

$\begin{array}{cc}4hours& Rs.60\\ 8hours& Rs.100\\ 12hours& Rs.140\\ 24hours& Rs.180\end{array}$

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

Answer 1

Charges per hour:
$C_1=\frac{60}{4}=Rs.15C_2=\frac{100}{8}=Rs.12.50C_3=\frac{140}{12}=Rs.11.67C_4=\frac{180}{24}=Rs.7.50$

Here, the charges per hour are not same, i.e.,
$C_1\ne C_2\ne C_3\ne C_4$
Therefore, the parking charges are not in direct proportion to the parking time.
