Question

Professor Croak wanted to find a smart trainer for his pet monsters. He devised a game to find
out a suitable trainer, in which he would place three identical metal balls with the monster in only
one of them and the other two empty.
Three written notes were kept in front of the balls marked 1, 2 and 3, and the trainer was
instructed to only read the statements on the notes and decide which ball to pick. Professor
Croak told the trainer that only one of the three statements was true and the other two were
false.
The notes had the following written on them:
1. This ball does not have the monster.
2. This ball has the monster.
3. The 2nd ball does not have the monster.
Which ball should the trainer pick?​

Answer 1

Answer:

The 1st Ball has the monster

Explanation:

The third statement can only be true due to logic, i.e., 3rd note says 2nd ball doesnt have, then 2nd note when converted to truth says 2nd ball doesnt have, and 1st note when converted to truth says 1st ball has. therefore , all statetments agree with each other when 3rd is picked as true note. Then all the notes say that 1st ball has the monster.
