Question

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?

Options

A) 840

B) 864

C) 920

D) 960

The correct answer is B.

Explanation:

\(\frac{\text{science}}{\text{graduates}}\) = \(\frac{\theta}{360}\) x 4320

where \(\theta\) + 100 + 80 + 108 = 360

\(\theta\) = 360 - 288 = 360

\(\frac{\text{science}}{\text{graduates}}\) = \(\frac{72}{360} \times 4320\)

= 864
