Answer 1

To find the percent efficiency, you can use the formula given:

\[ \text{Percent Efficiency} = \left( \frac{\text{Actual MA}}{\text{Theoretical MA}} \right) \times 100 \]

Substituting the values:

\[ \text{Percent Efficiency} = \left( \frac{10}{40} \right) \times 100 \]

\[ \text{Percent Efficiency} = 0.25 \times 100 = 25% \]

So the correct answer is 25%.
