To calculate percent efficiency using the formula provided:
\[
\text{Percent Efficiency} = \left( \frac{\text{Actual MA}}{\text{Ideal MA}} \right) \times 100
\]
Substituting the given values:
\[
\text{Percent Efficiency} = \left( \frac{10 \, \text{J}}{40 \, \text{J}} \right) \times 100
\]
\[
\text{Percent Efficiency} = \left( 0.25 \right) \times 100
\]
\[
\text{Percent Efficiency} = 25\%
\]
Thus, the percent efficiency is **25%**.
\[
