The total number of unsubscribed viewers from B is 3000 × $\frac{1}{15}$ = 200. The total number of unsubscribed viewers from C is 3000 × $\frac{2}{15}$ = 400. The total number of unsubscribed viewers in B and C and subscribed viewers in E is 200 + 400 + 180 = 780. What is the required central angle?

88.8°
90.0°
92.4°
93.6°

Correct answer: 93.6°

Solution

The required central angle is proportional to the number of viewers represented. Using 200 out of 3000, the angle is $(200/3000)\times 360 = 24\times 3.9 = 93.6^\circ$. So the correct answer is 93.6°.
