Exercise 5.2
Exercise 5.2
- A survey was made to find the type of music that a certain group of young people liked in a city. Adjoining pie chart shows the finding of this survey.
- If 20 people liked classical music, how many young people were surveyed?
- Which type of music is liked by the maximum number of people?
- If a cassette company were to make 1000 CD’s, how many of each type would they make?
- Number of people who like classical music = 10 %
This 10% present 20 people.
So, 10% represent = = 200 people.
Therefore, 200 young people were surveyed.
- From the pie chart, it can be easily observed that the light music is represented by the maximum part of the pie chart 40%. Hence, most of the people like light music.
- Number of CD’s of classical music = 10% of 1000
= 100
So, the number of CD’s of semi classical music = 20% of 100
= = 200
So, the number of CD’s of folk music = 30%
= = 300
And the number of cassettes of light music = 40% of 1000
= = 400
2. A group of 360 people were asked to vote for their favorite’s season from the three seasons rainy, winter and summer.
(i) Which season got the most votes?
