Question

The following table shows the component-wise expenditure. Draw a pie chart for the data.

Components	Expenditure (in Rs)
Raw Material	800
Labour	300
Transportation	100
Packing	100
Taxes	140

Answer 1

First, we compute the central angle for each subject, as shown in the following table .

Sr. No.	Mode of transport	Expenditure (in Rs)	Measure of central angle
1	Raw Material	800	$\frac{800}{1440}\times 360°=200°$
2	Labour	300	$\frac{300}{1440}\times 360°=75°$
3	Transportation	100	$\frac{100}{1440}\times 360°=25°$
4	Packing	100	$\frac{100}{1440}\times 360°=25°$
5	Taxes	140	$\frac{140}{1440}\times 360°=35°$
	Total	1440	360o
