... will be the force pushing down on the surface, so the force the 75 kg mass “feels” is the equal but opposite force pushing back up from the surface (Normal force). If the elevator was accelerating up, that would cause more force to be felt on the 75 kg mass. But in this case, the elevator is moving ...
