If profit is 50% of sales, then what is its percentage on cost?

The correct answer is C. 60%.

Let’s say the cost of a product is $100. If the profit is 50% of sales, then the selling price of the product is $150. The profit is $50, which is 60% of the cost of the product.

Here is a breakdown of each option:

• Option A: 100%. This is not the correct answer because the profit is not equal to the cost of the product.
• Option B: 75%. This is not the correct answer because the profit is not equal to 3/4 of the cost of the product.
• Option C: 60%. This is the correct answer because the profit is equal to 2/3 of the cost of the product.
• Option D: 40%. This is not the correct answer because the profit is not equal to 1/2 of the cost of the product.
