Uncle Cheng bought 2,500 shares of Minsheng Bank last year at a price of 4 yuan per share, and sold them at a price of 6 yuan per share on October 1 this year. In stock transactions, regardless of buying and selling, you must pay 0.3% stamp duty and 0.2% other fees. Please do the math, how much profit did Uncle Cheng make from buying the shares of Minsheng Bank?
成叔叔去年按每股4元的价格买了民生银行股票2500股，到今年10月1日按每股6元的价钱卖出．在股票交易中，无论买卖都要缴纳0.3%的印花税和0.2%的其他费用．请你算一算，成叔叔购买民生银行股票共获利多少元？
