Question : Study the pie chart and answer the question.
Distribution (degree wise) of the total number of employees of a company in its five offices A, B, C, D & E
Total number of employees = 9200
The total number of employees of the company in offices D and E is what percentage more than the number of employees in office A? (Your answer should be correct to one decimal place.)
Option 1: 21.8
Option 2: 20.6
Option 3: 21.4
Option 4: 22.2
Correct Answer: 21.4
Solution :
The total number of employees of the company in offices D and E
= $\frac{57.6+64.8}{360}×9200$
= $\frac{122.4}{360}×9200$
= 3128
Number of employees in office A
= $\frac{100.8}{360}×9200$
= 2576
Required percentage = $\frac{3128-2576}{2576}×100$
= $\frac{552}{2576}×100$
= 21.4%
Hence, the correct answer is 21.4%.
