NCERT Solutions Class 8 Mathematics Solutions for Exercise 13.1 in Chapter 13 - Direct and Inverse Proportions
Question 1 Exercise 13.1
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.
Answer:
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.
