The given histogram shows the frequency distribution of the speed of cars passing through at a parrticular spot on a haighway. 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/h ?
Show answer & explanation
Correct answer: A
Explanation
The correct answer is option 1 i.e. 8 : 7
The number of cars with speed less than 60 km/h = 50 + 70 = 120
The number of cars with speed more than 80 km/h = 60 + 45 = 105
Required ratio = 120/105 = 8 : 7
