The following Bar-Chart gives the production of cars by three different companies X, Y and Z in different years:
The percentage increase in the total production of cars from 2014 to 2018 was
100%
From the bar graph,
Total Production of car in 2014 = 300 + 200 + 500 = 1000
Total Production of car in 2018 = 700 + 500 + 800 = 2000
Therefore, Required percentage = \(total production of car in 2018 - total production of car in 2014 \over total production of car in 2014\)
The percentage increase in the total production of cars from 2014 to 2018 = (1000/1000) × 100 = 100%
∴ The required answer is 100%.
