A factory outlet has decided to dispose of its old stock by selling only one set of cups for Rs. 287, recovering only variable costs. If the fixed cost is 18% of the total cost, what was the cost price of each set of cups?
-
Rs. 320
-
Rs. 350
-
Rs. 325
-
Rs. 340
B
Correct answer
Explanation
The selling price of Rs. 287 covers only variable costs, meaning it's 82% of the total cost (since fixed cost is 18%). Let CP be the cost price. Then 82% of CP = 287, so CP = 287/0.82 = 350. Option A (320) would give variable cost of ~262. Option C (325) and D (340) don't satisfy the 82% ratio.
