A firm has sales of ₹8,00,000, variable costs of ₹4,80,000 and fixed costs of ₹2,00,000. What is the margin of safety as a percentage of sales?

The margin of safety is 37.5% of sales. The P/V ratio is 40%, so break-even sales are ₹5,00,000 (fixed costs ₹2,00,000 divided by 0.40). Actual sales exceed this by ₹3,00,000, which is 37.5% of ₹8,00,000.

  4. D40%

Explanation

P/V ratio = (8,00,000 - 4,80,000)/8,00,000 = 40%. Break-even sales = 2,00,000/0.40 = ₹5,00,000. Margin of safety = 3,00,000/8,00,000 = 37.5%, so the key is 37.5%.
