According to given pie chart in question , Corresponding angle for expenditure on electricity = 72°
Total angle for expenditure = 360°
Total percent for expenditure = 100%
⇒ 360° ≡ 100%
We know that ,∴ Required percent = Total percent for expenditure × Corresponding angle for expenditure on electricity Total angle for expenditure
Correct Option: D

Number of Non–members = 40
⇒ 5% = 40 ........( 1 )
Percent of cricket club only = 5%
⇒ Members of cricket club only = 40 { From ( 1 ) }Correct Option: B
