A12
B15
C20
D10 ✓ Correct
Correct answer: (D) 10 — The answer is 10 percent.
Explanation
★The answer is 10 percent.
★Take the marked price as 1 per pen, so 40 pens are marked at 40.
★The retailer pays the marked price of 36 pens, which is 36.
★Selling 40 pens with a 1 percent discount gives 40 times 0.99, which is 39.6.
★The profit is 39.6 minus 36, which is 3.6, and as a percent of 36 that is 10 percent.
★So the profit percentage is 10 percent.
★So the answer is 10 percent.
