Example 6: The given data shows the choice of favourite food for a group of people.
Favourite food North Indian South Indian Chinese Others
Number of people 30 40 25 25
Represent the data through a pie chart.
Solution: We first calculate the central angle for each component as shown below.
Favourite food Number of people Number of people who like a food
Central angle = × 360°
Total numberr of people
