Port Harcourt Refineries Plc has a breakeven sales revenue of ₦18,000,000 and a P/V ratio of 40%. What are the total fixed costs of the company?

At breakeven, total contribution equals total fixed costs. Total contribution at breakeven = P/V ratio × Breakeven sales = 40% × ₦18,000,000 = ₦7,200,000. Therefore, fixed costs = ₦7,200,000. Option A incorrectly applies 60% (the variable cost ratio), Option C divides instead of multiplying, and Option D halves the correct answer.
