The numbers of Commerce, Science and Arts postgraduates working in a company are 40, 80 and 60, respectively. If these
figures are represented by a pie chart, then what is the angle corresponding to Commerce postgraduates?

Correct option is B

Given:

Commerce postgraduates = 40

Science postgraduates = 80

Arts postgraduates = 60

Formula Used:

Angle $$= \left( \frac{\text{Category Value}}{\text{Total Value}} \right) \times 360^\circ$$​

Solution:

Total postgraduates = 40 + 80 + 60 = 180

Angle for Commerce postgraduates:

Angle = $$\left( \frac{40}{180} \right) \times 360 = \left( \frac{2}{9} \right) \times 360 = 80^\circ$$​
