A group of 360 people were asked to votefor their favourite season from the threeseasons rainy, winter and summer.
(i) Which season got the most votes?
(ii) Find the central angle of each sector.
(iii) Draw a pie chart to show thisinformation.
(i) Winter got the most number of votes as observed in the graph.
(ii) Central Angle can be calculated as follows:
Total number of votes:
90 +120 +150 = 360
Number of votes
(iii) The pie chart for the given data is:

The adjoining pie chart gives the marks scored in an examination by a student inHindi, English, Mathematics, Social Science and Science. If the total marks obtainedby the students were 540, answer the following questions.
(i) In which subject did the student score 105marks?
(Hint: for 540 marks, the central angle = 360°. So, for 105 marks, what is the central angle?)
(ii) How many more marks were obtained by thestudent in Mathematics than in Hindi?
(iii) Examine whether the sum of the marksobtained in Social Science and Mathematicsis more than that in Science and Hindi.
(Hint: Just study the central angles).
