[Solved] A man recently bought two aeroplanes, but afterwards found that they would not answer the purpose for which he wanted them. So he sold them for $600 each, making a loss of 20 percent on one machine and a profit of 20 percent on the other. Did he make a profit on the whole transaction, or a loss? And how much?

This riddle has been around for some time on internet platforms such as Instagram, Facebook, and WhatsApp, and many people still argue over what the answer might be, as there are many possibilities. The correct answer is The man made a loss of $50. The man must have paid $500 and $750 for the two aeroplanes, making together $1250; but as he sold them for only $1200, he lost $50 by the transaction.
