Answer:

220 hp

Explanation:

Let the input horsepower of the engine = x

The engine has a 5​% loss of power, therefore, its output is:


(100-5)\%\text{ of x}=95\%x=0.95x

Given that the engine's output = 209 hp.


0.95x=209

Divide both sides by 0.95 to solve for x:


\begin{gathered} (0.95x)/(0.95)=(209)/(0.95) \\ x=220\;hp \end{gathered}

The input horsepower of the engine is 220 hp.
