The given pie-chart represents the survey report on the favourite games of a group of young people.
If a total of 4980 people were surveyed, then what is the central angle produced by the sector indicating football?
Show answer & explanation
Correct answer: A
Explanation
The correct answer is option 1 i.e. 108°.
Given that
If a total of 4980 people were surveyed
The people who play football in the survey = 4980 × 30/100 = 1494
Total central angle = 360°
According to the question
⇒ 4980 = 360°
⇒ 1494 = (360/4980) × 1494 = 108°
Hence, the required central angle is 108°
