Question : Study the pie chart and answer the question.
If 50% of the employees in office E are transferred to office D, then what percentage of the total number of employees of the company is the number of employees in office D?
Option 1: 28
Option 2: 25
Option 3: 26
Option 4: 30
Correct Answer: 25
Solution :
Total employees = $360^\circ$
Number of employees in company E = $64.8^\circ$
Number of employees in company D = $57.6^\circ$
If 50% of employees of Company E transferred to Company D, then the number of employees in Company D $=57.6^\circ + \frac{64.8^\circ}{2}= 57.6^\circ + 32.4^\circ = 90^\circ$
Required percentage = $\frac{90^\circ}{360^\circ}$ × 100 = 25%
Hence, the correct answer is 25.
