Solution Steps

Step 1: Understanding Efficiency

Efficiency is a measure of how much of the input energy is converted into useful work. It is calculated using the formula:

\[ \text{Efficiency} = \left( \frac{\text{Useful Energy Output}}{\text{Total Energy Input}} \right) \times 100\% \]

Step 2: Calculating Useful Energy Output

Given that the motor loses \(25.0\%\) of its energy input to friction, the useful energy output is the remaining energy. Therefore, the useful energy output is:

\[ 100\% - 25.0\% = 75.0\% \]

Step 3: Determining the Efficiency

Since the useful energy output is \(75.0\%\) of the total energy input, the efficiency of the motor is \(75.0\%\).

Final Answer

\(\boxed{75.0\%}\)
