8th Class Mathematics Direct and Inverse Proportions

  • question_answer 1)                 Following are the car parking charges near a railway station up to 4 hours                 Rs 60 8 hours                 Rs 100 12 hours               Rs 140 24 hours               Rs 180 Check if the parking charges are in direct proportion to the parking time.

    Answer:

                    We have \[\frac{60}{4}=\frac{15}{1}\] \[\frac{100}{8}=\frac{25}{2}\] \[\frac{140}{12}=\frac{35}{3}\] \[\frac{180}{24}=\frac{15}{2}\] Since all the values are not the same, therefore, the parking charges are not in direct proportion to the parking time.
