Correct option is B
Step 1: Calculate Contribution to Sales (C/S) Ratio
The Contribution to Sales (C/S) Ratio, also known as the Profit-Volume Ratio (P/V Ratio), is calculated using the formula:

where Contribution is given by:
Contribution = Sales−Variable Cost
Since we are not directly given the variable cost, we use the Break-even Point (BEP) formula:

Given:
- Fixed Cost (FC) = ₹20,000
- Break-even Sales = ₹40,000
Rearranging:

Step 2: Calculate Profit
Profit = Total Contribution−Fixed Cost
Total Contribution:
= C/S Ratio×Total Sales
= 50%×100,000
= 50,000
Profit = 50,000 − 20,000
Profit = 30,000
Information Booster:
- Contribution to Sales (C/S) Ratio (or P/V Ratio) helps in understanding the profitability of a product. A higher C/S ratio indicates that a greater proportion of sales contributes to covering fixed costs and generating profit.
- Break-even Sales is the point where the company makes neither a profit nor a loss. It is important for decision-making and cost management.
- Profit Calculation involves subtracting fixed costs from total contribution, which shows how much actual profit remains after covering all fixed expenses.
