Also we can say ship absolute velocity is u=jet absolute velocity v,this is the condition for maximum efficiency. so
Relative velocity V+u=2u, 2v=2u,v=u so answer is correct.
Relative velocity V+u=2u, 2v=2u,v=u so answer is correct.

Since the maximum efficiency of jet propulsion of a ship with inlet orifices at right angles to the direction of motion of the ship is 50%.
