The given answer is correct because it matches the given information in the question. The question states that the P/V ratio is 40% and the margin of safety is 30%. Using these values, we can calculate the break-even point (BEP) by dividing the fixed cost by the contribution margin (1 - P/V ratio). In this case, the fixed cost is Rs. 92,000 and the P/V ratio is 40%, so the BEP is Rs. 92,000 / (1 - 0.4) = Rs. 1,53,333.
Additionally, the question asks for the profit if sales are Rs. 2,50,000. Using the formula Profit = (Sales - BEP) x P/V ratio, we can calculate the profit as (2,50,000 - 1,53,333) x 0.4 = Rs. 38,666.
Therefore, the given answer of Sales 2,30,000, Profit 30,000, and Fixed cost 92,000 is correct based on the calculations.
