Show answer & explanation

Correct answer: D

Concept

When profit percentage is calculated on expenditure, income equals expenditure plus profit.

Therefore, if the profit rate is r%, Income = Expenditure × (1 + r/100), so Expenditure = Income ÷ (1 + r/100).

Application

  1. For 2021, the table gives the income as ₹190 lakh.

  2. Use the revised profit rate: 25% = 25/100 = 0.25.

  3. Substitute in the income relation: 190 = Expenditure × (1 + 0.25) = Expenditure × 1.25.

  4. Divide both sides by 1.25: Expenditure = 190 ÷ 1.25 = ₹152 lakh.

Cross-check

At an expenditure of ₹152 lakh, profit is ₹190 lakh − ₹152 lakh = ₹38 lakh, and (38/152) × 100 = 25%. This reproduces the revised profit rate.

Hence, the expenditure would have been ₹152 lakh.
