Charts

  UPSC Prelims 2022--> Q) A pie chart gives the expenditure on five different items A,B,C,D and E in a household. If B,C,D and E corresponds to 90^o, 50^o, 45^o  and 75^o respectively, then what is the percentage of expenditure item A?

^{Solution :-} 

^{For Pie chart Total Angle  = 360o}

Angle for B = 90^o

Angle for C = 50^o

Angle for D = 45^o

Angle for E = 75^o

Angle for B = 360^o - 90^o - 50^o - 45^o - 75^o = 100^o

 

 

^{Percentage Expenditure of Item A}

100 x ¹⁰⁰⁄₃₆₀ = ¹⁰⁰⁰⁰⁄₃₆₀  = ¹⁰⁰⁰⁄₃₆ = ²⁵⁰⁄₉
