Model Answer
(c) Rs. 32,500/-
Average income = (50,000 + 40,000 + 20,000 + 20,000) ÷ 4 = 1,30,000 ÷ 4 = Rs. 32,500/-
Explanation
Average (mean) = sum of all values ÷ number of values. Add all four incomes and divide by 4. This links to the textbook concept of per capita/average income used to compare development levels.
