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?
-
A.
840 -
B.
864 -
C.
920 -
D.
960
Correct Answer: Option 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
