The pie chart shows the distribution of 4320 students who graduated from four departments in a university. How many students graduated from the science department?
840
864
920
960
Correct answer is B
\(\frac{\text{science}}{\text{graduates}}\) = \(\frac{\theta}{360}\) x 4320
where \(\theta\) + 100 + 80 + 108 = 360
\(\theta\) = 360 - 288 = 360
\(\frac{\text{science}}{\text{graduates}}\) = \(\frac{72}{360} \times 4320\)
= 864
