Part (i): Current Level of Sales
When sales increase by 5%, only variable costs increase proportionately; fixed costs remain unchanged. Therefore, the increase in EBIT equals the increase in Contribution.
Increase in Contribution = 5% × Sales × Contribution Margin Ratio
Since this increase equals ₹9,000:
5% × Sales × 40% = ₹9,000
Sales = ₹9,000 / (0.05 × 0.40) = ₹9,000 / 0.02
Current Level of Sales = ₹4,50,000
Part (ii): Operating, Financial and Combined Leverage
From the current sales level, the income statement structure is built as follows:
Sales = ₹4,50,000; Contribution (40%) = ₹1,80,000; Less: Fixed Operating Cost = ₹1,35,000; EBIT = ₹45,000; Less: Interest = ₹30,000; EBT = ₹15,000.
Operating Leverage (OL) measures the sensitivity of EBIT to changes in sales and is calculated as:
OL = Contribution / EBIT = ₹1,80,000 / ₹45,000 = 4
This means a 1% change in sales will result in a 4% change in EBIT.
Financial Leverage (FL) measures the sensitivity of EBT (earnings available to equity) to changes in EBIT:
FL = EBIT / EBT = ₹45,000 / ₹15,000 = 3
This means a 1% change in EBIT will result in a 3% change in EBT.
Combined Leverage (CL) captures the overall effect of a change in sales on EBT:
CL = OL × FL = 4 × 3 = 12
Alternatively, CL = Contribution / EBT = ₹1,80,000 / ₹15,000 = 12
This implies that a 5% increase in sales will lead to a 60% increase in EBT (5% × 12), reflecting the magnified impact of both operating and financial fixed costs.
