For a pie chart, a studen t calculates the central angle of a component as `72^(@)` by taking the total value as 220 instead of 240. Find the correct central angle of the component.

A

`60^(@)`

B

`66^(@)`

C

`74^(@)`

D

`80^(@)`

Text Solution

Verified by Experts

The correct Answer is:
B
Let the value of the component be x.
`x/220xx360^(@)=72^(@)`
`x=44`
`:.` The correct central angle of the component
`=44/240xx360^(@)=60^(@)`
