      expenditure on Rent, Food, Education and Miscellaneous are shown by central angles 90 degrees, 120 degrees, 60 degrees and 45 degrees respectively. If the total monthly income is Rs 36000, then the difference between the amounts spent on Food and Savings is:
      A 6520 Correct Answer Incorrect Answer
      B 7500 Correct Answer Incorrect Answer
      C 4750 Correct Answer Incorrect Answer
      D 3325 Correct Answer Incorrect Answer

      Solution

      ATQ, Total angle used: 90 + 120 + 60 + 45 = 315 degrees So Savings angle = 360 - 315 = 45 degrees Food amount = 120/360 x 36000 = 12000 Savings amount = 45/360 x 36000 = 4500 Difference = 12000 - 4500 = 7500
