Model Answer
Option A: ₹ 25,000
Average income = (₹10,000 + ₹20,000 + ₹30,000 + ₹40,000) ÷ 4 = ₹1,00,000 ÷ 4 = ₹25,000
Explanation
Average (per capita) income is calculated by dividing the total income by the number of families. This is a straightforward calculation tested in Ch. 1. Remember: the CBSE textbook uses average/per capita income as a basic development indicator, but also points out its limitations (it hides unequal distribution).
