Calculating Sharpe Ratio for Fund A

As an investment analyst, you are conducting an assessment of different mutual funds to determine which ones provide the best risk-adjusted returns. You decide to evaluate three different funds using the Sharpe ratio, a commonly used risk-adjusted performance measure. The Sharpe ratio is calculated by subtracting the risk-free rate from the investment return and dividing this result by the standard deviation of the investment's excess return.

If Fund A has a return of 10%, a standard deviation of 15%, and the risk-free rate is 2%, what is the Sharpe ratio for Fund A?
