The given histogram shows the frequency distribution of the speed of cars passing though at a particular spot on a highway. Study the graph and answer the question that follows.

What is the ratio of the number of cars with speed less than 60 km/h to the number of cars with speed more than 80 km/hr?

8 : 7

Cars with speed less than 60 km/h      :    Cars with speed more than 80 km/h

              ( 50 + 70 )                          :        ( 60 + 45 )

                   120                                :            105

                     8                                  :            7
