If John buys two pens at the same price, but sells one pen at a 15% profit and the other at a 15% loss, what is the overall profit or loss percentage? A:) He makes no profit and no loss. B:) He makes a profit of 2.25%. C:) He suffers a loss of 2.25%. D:) He suffers a loss of 5%. by using your formula i came to an answer that option c is the right answer but now im confused by one explanation which is saying that the answer is A Let's assume that John buys two pens at the same price of $x$ dollars each. Therefore, his total cost is $2x$ dollars. John sells one pen at a 15% profit. This means that he sells the pen for $1.15x$ dollars. He sells the other pen at a 15% loss, which means he sells the pen for $0.85x$ dollars. Therefore, John's total revenue is $(1.15x) + (0.85x) = 2x$ dollars. His total cost is also $2x$ dollars, which means he makes neither a profit nor a loss. Therefore, the answer is (a) He makes no profit and no loss. In other words, the overall profit or loss percentage is 0%. clarify my doubt sir
