The Esplanade conducted a survey to find out the favourite performance art that the audience preferred. The pie chart below shows the survey results and a table that shows part of the results collected.

How many audience selected Symphony Orchestra as their favourite performance art?

Solution:

Per the pie chart,

¼ fraction of the pie chart ==> Chinese dance

¼ fraction of the pie chart ==> Choir

The number of audience selected Chinese = 50

½ of the pie chart ==> 2 × 50 = 100 audience

The number of audience selected Symphony Orchestra = 100 – 78 = 22
