Antique lampsMath brain teasers require computations to solve.
A collector of antique lamps bought two lamps, and then, discovering she was short of money, immediately had to sell them again. She sold each lamp for $600. On one of the lamps she made 20% and on the other one she lost 20%. Did she make or lose money on the whole deal? How much?
AnswerShe lost money. You can calculate that the one lamp cost $500 and the other one cost $750. That means she paid $1250 for them together and then sold them for $1200 losing $50.
