The following Bar-Chart gives the production of cars by three different companies X, Y and Z in different years:
In one of the years the percentage increase in production of cars was minimum as compared to its previous year. What was the minimum percentage ?
From the bar graph,
Total Production of car in 2014 = 300 + 200 + 500 = 1000
Total Production of car in 2015 = 400 + 300 + 500 = 1200
Percentage of production increase of from 2014 to 2015 = (200/1000) × 100 = 20%
Total Production of car in 2016 = 500 + 400 + 600 = 1500
Percentage of production increase of from 2015 to 2016 = (300/1200) × 100 = 25 %
Total Production of car in 2017 = 600 + 500 + 700 = 1800
Percentage of production increase of from 2016 to 2017 = (300/1500) × 100 = 20%
Total Production of car in 2018 = 700 + 500 + 800 = 2000
Percentage of production increase of from 2017 to 2018 = (200/1800) × 100 = 11.11%
∴ The minimum percentage is 11.11% ( \(11 \frac{1}{9} \%\) ).
The percentage increase in the total production of cars from 2014 to 2018 was
