A pie chart gives the expenditure on five different items A, B, Q D and E in a household. If B, C, D and E correspond to 90o ,50o, 45o and 75o respectively, then what is the percentage of expenditure on item A?
Explanation:
A pie-chart corresponds to 3600.
Items B, C, D and E correspond to 900, 500, 450 and 750 respectively on the pie chart.
Angle corresponding to A in the pie-chart = 3600 – (900 + 500 + 450 + 750) = 1000
So, Percentage of expenditure on item A = (100/360) × 100 = (250/9)%
