Question 149
The following pie-chart shows the monthly expenditure of a family on food, clothing, rent. miscellaneous expenses and savings. What is the central angle for savings ?
Solution
Central angle of a circle = 360°
Now, central angle for :
food = 108°
rent = 90°
clothing = 36°
misc = 72°
=> Central angle for savings = 360° - (108°+90°+36°+72°)
= 360° - 306° = 54°
