When in doubt, plug each answer into the formula until you get the correct answer. Example 5.3-1/X=2 A. 5.3-1/2.15=2 B. 5.3-1/3.15=1.365 C. 5.3-1/4.34=.9907 D. 5.3-1/6.37=.675 The answer is A. Just a note to help. |

It would also be good to know how to convert any formula: Sharpe Ratio=(Rp-Rf)/portfolio standard deviation Portfolio standard deviation = (Rp-Rf)/Sharpe ratio |

Set up the equation and solve for the unknown "x". 5.3-1/X=2 x = 4.3/2 x = 2.15 |
