Question

Three friends, Jose, Michael, and Andrea, play a game in which each decides to be either a liar or a truth teller. A liar must always lie and a truth teller must always tell the truth. When you met your friends, you asked Jose which he had chosen to be. You didn't hear his answer but Michael stated, "Jose said that he is a liar." Andrea said, " If one of us is a liar, then we are all liars." Can you determine, for each person, whether he is a liar or a truth teller?​
please help

Answer 1

This question is based on logic.

As given, there are three friends, Jose, Michael, and Andrea. They are playing a game where each decides to be either a liar or a truth teller. A liar must always lie and a truth teller must always tell the truth.

As Michael stated, "Jose said that he is a liar." this means Michael is a truth teller because as per the game rule, he is telling the truth. So this gives Jose as a liar.

Andrea said, " If one of us is a liar, then we are all liars." This makes Andrea a liar as Michael's statement already proved that he is the truth teller.

Hence, Michael is a truth teller and Jose ans Andrea are liars.
