Ali gives the following percentage of his time to different subjects. He gives 10% time to Islamiat, 20% to Science, 20% to Urdu, 20% to Mathematics and 30% to remaining subjects. What is the angle of the remaining subjects on the pie chart?
- 144°
- 120°
- 108°
- None of these
Explanation
To find the angle for the remaining subjects on the pie chart:
Percentage for remaining subjects = 30%
Since a circle is 360° and represents 100%,
Angle for remaining subjects = (30/100) * 360°
= 0.3 * 360°
= 108°
