Answer:
0.4 or 40%
Explanation:
the formula used to calculate the reward variability ratio is:
reward variability ratio = (expected return - risk free rate) / standard deviation = (20% - 10%) / 25% = 10% / 25% = 0.4 = 40%
The reward variability ratio measures the return of a project, stock or investment, adjusted for its variability (standard deviation) compared to the risk free rate.
