Question
In a pie chart of monthly expenditure, the central
angles for Rent, Food, Education and Miscellaneous are 72 degrees, 108 degrees, 90 degrees and 54 degrees respectively. If the total monthly expenditure is Rs 36000, then the difference between expenditure on Food and Savings is:Solution
Total used angle = 72 + 108 + 90 + 54 = 324 degrees Savings angle = 360 - 324 = 36 degrees Food expenditure = 108/360 x 36000 = 10800 Savings expenditure = 36/360 x 36000 = 3600 Difference = 10800 - 3600 = 7200
