Question

A survey gives the following information of food items preferred by people. Draw a Pie chart.

Items	Vegetables	Meat	Salad	Fruits	Sprouts	Bread
No. of people	160	90	80	50	30	40

Answer 1

Total number of people = 160 + 90 + 80 + 50 + 30 + 40

= 450

Converting the number of people prefer various food items into components part of 360°

Central angle of a component = `"Value of the component"/"Total value" xx 360^circ`

Item	Number of people	Central angle
Vegetables	160	`16/450 xx 360^circ` = 128°
Meat	90	`90/450 xx 30^circ` =  72°
Salad	80	`80/450 xx 360^circ` = 64°
Fruits	50	`50/450 xx 360^circ` = 40°
Sprouts	30	`30/450 xx 360^circ` = 24°
Bread	40	`40/450 xx 360` = 32°
Total	450	360°

Food items are preferred by people.
