18th edition niceic-elearn question

MikeWilson

Looking for help on this question as I am completely stumped, every what seems to be feasible answer is apparently wrong.

   

Can anybody please advise?

    Yep I'd go for 11 are turned off , 6 on top bar, 5 on lower.and complain to the exam board and ask them to show their working if they disagree. But then I'm like that ;- )

    Unless the answer is 'none they are all  AFDDs...' in which case I'd definitely complain !
    Of course at least one of them would do nothing even if turned on - the rightmost of the bank of three on the lower bar has  no outbound, but that is not the question it is still not in the 'ON'  position.
