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 correspond to 90 degrees, 50 degrees, 45 degrees and 75 degrees respectively, then what is the percentage of expenditure on item A?
112/9
125/6
155/9
250/9
Solution
A full pie chart is 360 degrees. The angle for A = $360 - (90 + 50 + 45 + 75) = 100$ degrees. So the percentage of expenditure on A = $(100/360) \times 100 = 250/9$ %.
