Aunt Zhang deposited 50,000 yuan in the bank for a period of three years, with an annual interest rate of 2.52%. Due to the urgent need for money, I had to withdraw the savings that had been deposited for two and a half years. At this time, the current calculation is based on the annual interest rate of 0.72%. How much less will this be than the interest received after the original maturity?
张阿姨将50000元存入银行，定期三年，年利率是2.52%．由于急需用钱只得将存了两年半的存款取出，此时按年利率0.72%的活期计算．这样比原本到期后取得的利息少拿多少元？
