1 版本一:半年复利2%投资多少元=于10,000元在季度利息4%一年的利润,这题我tm算了10分钟,选项有10400,10800,20000,我选了个10800 版本二:X按照2%半年复利计算=10000按照4%的季度复利计算。问X的值 GMATdeJULY:原题好像是多少钱半年复利一年2%=10000季度利率复利一年4%,半年的那个本金是X X*1.1^2=10000*1.1^4,x=10200,1年利率2%,半年就是1% 1年利率是4%,1个季度利率就是1%,俩个都是复利 Jenny hu:x(1+.02/2)^2=10,000(1+.04/4)^4,x=10201 I'm assuming the question is saying annual interest compounded semiannually and quarterly. Semiannually compounded needs to divide by 2 and quarterly compounded needs to divide by 4.
偶有点晕---题目的意思是说:
半年复利2%投资多少元 -- annual rate 2%, compunded semiannually. 于10,000元在季度利息4%一年的利润 --- annual rate 4%, compounded quarterly,
另外:如果从这个公式:x(1+.02/2)^2=10,000(1+.04/4)^4,x *1.1^2=10,000*1.1^4 x应该等于10,000*1.1^2=12100啊。。。
