Explanation / Answer

For Each statemnt

1)
let #12 speaks truth
#17 is lying that is he is inncoent
and #31 is lying that is #12 is guilty
in this case we get one persons who speak truth
#12 so both are lying that is proved
2)
now let say #17 is saying truth
then #12 is lying
that he is inncoent
and #31 says #12 is guilty
that is true because from #12 staement we can conclude that
so in this case we have two truth tellers
#17,#31 so liare can't be veified from this
3)
now take #31 as truth
that #12 is gulty
then both #12 and #17 telling lie that is
two person is telling truth
that is #31,#17

so from all above assumptions
we get that
whan #12 says the truth and #17 robbed the bank
because #31 said #12 is guilty and that we proved false in
