The number of cars passing the road near a colony from 6 am to 12 noon has been shown in the following histogram.
What is the maximum change percentage in the number of cars as compared to the previous hour? (correct to 2 decimal places)
Answer & explanation
Correct answer: option 1
Percentage change in 7-8 as compared to 6-7 = \(\frac{35}{70}\) × 100
= + 50%
Percentage change in 8-9 as compared to 7-8 = \(\frac{25}{105}\) × 100
= + 23.80%
Percentage change in 9-10 as compared to 8-9 = \(\frac{15}{130}\) × 100
= - 11.53%
Percentage change in 10-11 as compared to 9-10 = \(\frac{20}{115}\) × 100
= - 17.39%
Percentage change in 11-12 as compared to 10-11 = \(\frac{50}{95}\) × 100
= - 52.63%
Ans is = Decrease of 52.63%
