For a lump sum investment of 250,000 invested at a stated annual rate of 3% compounded daily, the number of months needed to grow the sum to 1,000,000 is closest to:
A.555
B.563
C.576
答案是A, 是把3%compound daily换算成EAR, 再根据计算器算出来的年份乘以12算出最后所需compound的月份。
我的答案是B,是直接用3%/365算出daily rate=1/Y, 然后计算器算出所需天数再除以30算出compound的月份。
我想知道为什么不能用天算而要一定要先换算成EAR再算?
谢谢您!
