I am having time finding out the answer to this problem.
the math I did was...
input voltage x input current = input power ( watts)
output voltage x output current = output power ( watts)
output power/input power = total output.
I did that and come up with 33.33
that isn't any of the answers to choose I am wondering if I am missing something in the problem. thanks for your help
