Draw a pie chart showing the following information. The table shows the colours preferred by a group of people.
The central angle for each angle can be calculated as:
Number of people
Pie chart of the above data:
A survey was made to find the type of musicthat a certain group of young people liked ina city.Adjoining pie chart shows the findingsof this survey.
From this pie chart answer the following:
(i) If 20 people liked classical music, howmany young people were surveyed?

(iii) If a cassette company were to make1000 CD’s, how many of each typewould they make?
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).
