Question : Study the pie chart and answer the question:
The total number of employees of the company working in the production and IT department exceeds the total number of employees working in the Marketing and Accounts departments by ________.
Option 1: 143
Option 2: 164
Option 3: 158
Option 4: 154
Correct Answer: 154
Solution :
Given: Total employees = 1400
The total number of employees working in the Production and IT department = $111.6^\circ+72^\circ$
= $183.6^\circ$
The total number of employees working in Marketing and Accounts = $86.4^\circ+57.6^\circ$
= $144^\circ$
Difference = $183.6^\circ-144^\circ=39.6^\circ$
Required number of employees = $\frac{\text{Difference}}{360^\circ}\times$ total employees
= $\frac{39.6^\circ}{360^\circ}\times1400$
= 154
Hence, the correct answer is 154.
