Sarah always tells the truth, Sue always lies, and Sally sometimes lies and sometimes tells the truth. When Victor asked each sister a question to identify them, Sarah correctly identified herself as being on the left, Sally identified herself as being in the middle, and Sue identified the middle sister as herself, confusing Victor as to their identities.
2. ? Three sisters are identical triplets. The
oldest by minutes is Sarah, and Sarah
always tells anyone the truth. The next
oldest is Sue, and Sue always will tell
anyone a lie. Sally is the youngest of the
three. She sometimes lies and sometimes
tells the truth.
3. ? Victor, an old friend of the family's, came over one
day and as usual he didn't know who was who, so
he asked each of them one question.
? He asked the sister on the left, "Which sister is in
the middle of you three?" She said, ^Sarah."
? He asked the sister in the middle, "What is your
name?" Her response was, "I'm Sally."
? He asked the sister on the right, "Who is that in the
middle?" She replied, "She is Sue."
? This confused Victor. Who was who?
