※ 引述《little444 (胖妞妞胖)》之銘言：
: Jack invested an amount of money in municipal bonds that
: yield 10 percent interest per annum, and Tom invested in treasury
: bills that yield 2 percent less than municipal bonds.
: If the money Tom invested was two times as much as the money Jack
: invested, in 2 years the interest Jack earned was what percent of
: the interest Tom earned?
: ___________________________________________________________________
: Ans: 62.5%
由題目資訊 假設如下
principle rate (annum) interest earned after two year
Jake P 10% P*10%*2=0.2P
Tom 2P 8% 2P* 8%*2=0.32P
0.2P/0.32P=62.5%
