Question : 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 speeds less than 60 km/hr to the number of cars with speeds more than 80 km/hr?
Option 1: 8 : 7
Option 2: 4 : 5
Option 3: 5 : 4
Option 4: 7 : 8
Correct Answer: 8 : 7
Solution :
As per the graph,
The number of cars with speeds less than 60 km/hr = 50 + 70 = 120
The number of cars with speeds more than 80 km/hr = 60 + 45 = 105
The required ratio = 120 : 105 = 8 : 7
Hence, the correct answer is 8 : 7.
