TammTamm 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.
Meka76 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
RCapistrano Set up the equation and solve for the unknown "x".

5.3-1/X=2
x = 4.3/2
x = 2.15
2014 after u minus return - risk
u look at possible answers givn in question and just select
