The given histogram shows the frequency distribution of the speed of cars passing through at a particular spot on a highway. Study the graph and answer the question that follows. What percentage of cars were running with a speed of less than or equal to 70 km/h?

The given histogram shows the frequency distribution of the speed of cars passing through at a particular spot on a highway. Study the graph and answer the question that follows. What percentage of cars were running with a speed of less than or equal to 70 km/h? Correct Answer 51.25%

Given:

Total number of cars 

50 + 70 + 85 + 90 + 60 + 45 = 400

Total numbers of cars with speed less than 70 km/h

50 + 70 + 85 = 205

Formula used:

Percentage = (Part value/Original value) × 100

Calculation:

Percentage of cars running with speed less than 70 km/h

⇒ (205/400) × 100

⇒ 51.25%

∴ The percentage value is 51.25%.
