My apprentice is about to take his Journeyman's test this Thursday through PSI. He got a question wrong on his PSI Practice Test and asked me for input. I'm embarrassed to say I couldn't see how they came up with their answer.

Q: What is the motor nameplate FLA rating for a 5 HP single-phase motor, 230 volt with an efficiency rating of 95% and a power factor of 90%?

A: 8 amps

B: 16amps

C: 19amps

D: 25amps

My apprentice chose the answer D, but the correct answer is C according to the practice test. Can anyone explain the formulas needed to come up with the answer? Any help would be appreciated!

The question makes no sense.
