The first group is pretty straight forward.
D has to be a Liar, as it is a given that
at least 1 of them is a knight.
Of the remaining 3, since all are making contradictory statements, only 1 can possibly be a Knight.
Hence, B is a Knight and A C and D are
The other group starts in a similar manner,
but gets tricky with subsequent statements ... more so due to the hush of a
certain Mr H.
E has to be a Liar, as it is a given that
at least 1 of them is a Knight.
Between F and G, both cannot be knights,
due to their contradictory statements.
If both of F and G were Liars, then H has
to be the Knight ... but then G's statement turns out to be true.
So between F and G ... one is a knight and
the other is a Liar ... irrespective of what H is!<o:p></o:p>
F cannot be a knight, as then G has to be a
knight as well ... [we have already determined that E has to be a Liar]<o:p></o:p>
So F is a Liar, which makes G a knight, and
H a liar ... despite his silence!
