In May of last year, Nanjing lowered the part of the individual payment of deed tax on house purchases from the original 2% to 0.75%, and the remaining 1.25% was subsidized by local finance. From June 11 this year, the individual payment of deed tax for house purchases will resume to 2%. How much less will it cost to pay taxes before June 11 this year than after June 11 to buy a commercial house worth 600,000 yuan?
去年五月，南京市将购房契税个人缴纳部分由原来的2%下调至0.75%，其余的1.25%由地方财政补贴．今年六月十一日起购房契税个人缴纳部分将恢复至2%．这样购买价值60万元的商品房，在今年六月十一日前缴税比在六月十一日后缴税，要少花多少元？
