问题如下:
An investment of €500,000 today that grows to €800,000 after six years has a stated annual interest rate closest to:
选项:
A.7.5% compounded continuously.
B.7.7% compounded daily.
C.8.0% compounded semiannually.
解释:
C is correct,
as shown in the following (where FV is future value and PV is present value): If: FVN = PV(1 + rs/m)mN, Then: rs = 0.07988 (rounded to 8.0%)
老师好用公式fv/pv=(1+r/m)m次方的公式算出,为什么是r/2,代入半年计息一次不应该是12么,就是最后一步没看懂
