In a pie diagram, there are four slices with angles 150°, 90°, 60° and 60°. A new pie diagram is formed by deleting one of the slices having angle 60° in the given pie diagram. In the new pie diagram
Elementary MathematicsStatistics
- AThe largest slice has angle 150°
- BThe smallest slice has angle 70°
- CThe largest slice has angle 180°
- DThe smallest slice has angle 90°
Explanation
Deleting one 60° slice leaves 300°; rescaling by 360/300: 150° → 180°, 90° → 108°, 60° → 72°. The largest slice is now 180°: option C. Option A forgets to rescale.
