The following Pie-Charts show the percentage of different categories (A, B, C, D, E and F) of employees in a company in the year 2019 and 2020. The total number of employees was 4000 in 2019 and 5000 in 2020.
In which one of the following categories of employees, the percentage change in number of employees in 2020 was maximum as compared to 2019?
B
From Given :
For category A,
Total number employee of category A in 2019 = 20 × 4000/100 = 800
Total number employee of category A in 2020 = 22 × 5000/100 = 1100
Percentage change = 300/800 × 100 = 37.5%
For category B,
Total number employee of category B in 2019 = 6 × 4000/100 = 240
Total number employee of category B in 2020 = 10 × 5000/100 = 500
Percentage change = 260/240 × 100 = 108.33%
For category C,
Total number employee of category C in 2019 = 10 × 4000/100 = 400
Total number employee of category C in 2020 = 11 × 5000/100 = 550
Percentage change = 150/400 × 100 = 37.5%
For category D,
Total number employee of category D in 2019 = 15 × 4000/100 = 600
Total number employee of category D in 2020 = 9 × 5000/100 = 450
Percentage change = (-)150/600 × 100 = (-)25%
For category E,
Total number employee of category E in 2019 = 27 × 4000/100 = 1080
Total number employee of category E in 2020 = 27 × 5000/100 = 1350
Percentage change = 270/1080 × 100 = 25%
For category F,
Total number employee of category F in 2019 = 22 × 4000/100 = 880
Total number employee of category F in 2020 = 21 × 5000/100 = 1050
Percentage change = 110/440 × 100 = 25%
From the above calculation
So, Percentage change is maximum for B
∴ The correct answer is B.
