In a survey to analyze eating habits of different people, it was observed that 60% of people are non-vegetarians (N), 25% of people are eggetarians (E) and 15% of people are vegetarians(V). Find the angles θN, θE and θV from the pie chart.
= ,= ,=
For every x of total people, the angle in the pie chart will be x of total angle i.e. 360∘.
θN = (percentage of non-veg people) × 360∘
θN = 60100 × 360 = 216∘
Similarly, θE = 25100 × 360 = 90∘
and θV = 15100 × 360 = 54∘
