The number of hours spent by a student on different activities as shown in the following pie chart:
The central angle corresponding to the sleeping time is what percentage of the whole central angle?
Show answer & explanation
Correct answer: B
Explanation
The correct answer is option 2 i.e. 33.33%
Given that
The number of hours spent by a student on different activities, like
School = 6 hours
Home work = 5 hours
Play = 3 hours
Sleep = 8 hours
Others = 2 hours
Total hours = 6 + 5 + 3 + 8 + 2 = 24 hours
As we know the whole central angle is 360º
The central angle corresponding to the sleeping time = 360º × 8/24 = 120º
Hence, the required percentage = (120º/360º) × 100 = 100/3 = 33.33%
