Question:
The given pie chart shows the breakup (in percentage) of monthly expenditure of a person.The central angle made by the sector of expenditure on Fuel is how much (in degrees) if the ratio of the expenditure on Fuel and Clothes is 4 : 3 respectively?
A32°
B36°
C45°
D72°
Answer:
D. 72°
Explanation:
Expenditure on clothes = 15% central angle made by the sector of expenditure on clothes = x° Total angle = 360° 15/100 = x/360 x = 360° × (15/100) x = 54° Central angle made by the sector of expenditure on clothes = 54° central angle made by the sector of expenditure on fuel = y° y/54° = 4/3 y = 54° × (4/3) y = 72° Central angle made by the sector of expenditure on fuel = 72°
