The pie chart shows the results of an online survey which asked people about their favourite movie. Study the diagram and answer the following questions.
The measure of the central angle of the sector representing number of people whose favourite movie is C is ________ degrees.
Number of people whose favourite movie is CÂ = 100
Total numbers of people who have responded to the survey
= 450 + 300 + 100 + 300 + 350 + 250 + 50 = 1800
=> Required central angle = $$\frac{100}{1800}\times360^\circ$$
= $$\frac{100}{5}=20^\circ$$
=> Ans - (B)
