Study the pie-chart and answer the question.
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.)
Answer & explanation
Correct answer: option 3
Employees in D & E together = 57.6º + 64.8º = 122.4º
Employees in A = 100.8º
Required percentage = \(\frac{122.4º - 100.8º}{100.8º}\) × 100
= \(\frac{21.6º}{100.8º}\) × 100
= 21.4%
