The fruit shop purchased 600 kilograms of watermelons with 1200 yuan and raised the price by 25% (price) and sold it (2/3), and the rest were sold out at half the price. May I ask: Is this watermelon business a profit or a loss? How much did you earn (or lose)?
水果店用1200元购进600千克西瓜先提价25%(标价)销售了(2/3)，剩下的按标价的一半售完，请问：这笔西瓜生意是赚还是亏？赚了(或亏了)多少元？
