The pie chart below represents the monthly expenditure distribution of five individuals (A, B, C, D, and E) across four categories: Rent, Utilities, Groceries, and Miscellaneous. Each individual has a total monthly expenditure of ₹75,000.Solution
Each individual has a total monthly expenditure of ₹75,000. Expenditure on Rent (for the average person): Rent expenditure = 50% of ₹75,000 = (50/100) × 75,000 = ₹37,500 Individual A spends 10% less on Rent: 10% less than ₹37,500 = ₹37,500 × 0.10 = ₹3,750 Total expenditure on Rent by individual A = ₹37,500 - ₹3,750 = ₹33,750 Expenditure on Utilities (for the average person): Utilities expenditure = 15% of ₹75,000 = (15/100) × 75,000 = ₹11,250 Individual A spends 5% more on Utilities: 5% more than ₹11,250 = ₹11,250 × 0.05 = ₹562.50 Total expenditure on Utilities by individual A = ₹11,250 + ₹562.50 = ₹11,812.50 Total expenditure by individual A on Rent and Utilities together: ₹33,750 (Rent) + ₹11,812.50 (Utilities) = ₹45,562.50 Ans.
