Question

Number of students admitted in different faculties of a college are given below.

Faculty	Science	Commerce	Arts	Law	Home Science
No. of students	1000	1200	650	450	300

Draw a pie diagram representing the above data.

Answer 1

First, we have to compute the central angle for each faculty, as shown in the following table .

Sr. No.	Faculty	No. of students	Measure of central angle
1	Science	1000	$\frac{1000}{3600}\times 360°=100°$
2	Commerce	1200	$\frac{1200}{3600}\times 360°=120°$
3	Arts	650	$\frac{650}{3600}\times 360°=65°$
4	Law	450	$\frac{450}{3600}\times 360°=45°$
5	Home Science	300	$\frac{300}{3600}\times 360°=30°$
	Total	3600	360o

The pie diagram for the data is shown below.
