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?
Show answer & explanation
Correct answer: B
Explanation
The correct answer is option 2 i.e. 80°.
Total numbers of Commerce, Science, and Arts postgraduates working in a company = 40 + 80 + 60
⇒ 180
According to the question;
The total angle of degree in a pie chart = 360°
⇒ 180 = 360°
⇒ 1 = 2°
Hence, the required angle corresponding to Commerce postgraduates = 40 × 2° = 80°
