The cost price of an article is 75% of its marked price. How much percent does the tradesman gain after allowing a discount of 15%?
A20%
B13 and one-third % ✓ Correct
C10%
D15 and two-third %
Correct answer: (B) 13 and one-third % — The gain is 13 and one-third percent, so that is the answer.
Explanation
★The gain is 13 and one-third percent, so that is the answer.
★Let the marked price be 100, so the cost price is 75.
★A discount of 15 percent gives a selling price of 85.
★The profit is 85 minus 75, which is 10.
★Profit percent is 10 over 75 times 100.
★This equals 13 and one-third percent.
