Mathematics nearby Mr. Hui bought a new car with $100,000 He makes up the car well and then try to sell it at a better price. So, he marked up 50% (half). His friend wants to buy a car also and then he approached Mr. Hui. Mr. Hui decided to sell it to his friend at a “friendship price” of 50% (half) of the marked price. Did Mr. Hui gain, lose or no gain no loss?

Mathematics nearby Cost Price = $100,000 Marked Price = $100,000 (1+50%) = $150,000 Selling Price = $150,000 (1-50%) = $75,000 Since Selling Price < Cost Price, Mr. Hui lost!
