The treasure is in the 2nd chest. ✅
Here is the logical deduction proving why this is the only possible solution, based on the dragon’s rule (which states that exactly one of the three statements is true):
Let’s examine what happens if the treasure is in the different chests:
🟡 If the treasure were in the 1st chest:
-Inscription on the 1st chest (“The treasure is in this chest”): TRUE
-Inscription on the 2nd chest (“The treasure is not in this chest”): TRUE (since it is in the 1st, it is indeed not in the 2nd)
-This results in two true statements, which contradicts the dragon’s rule. Therefore, the treasure cannot be in the 1st chest.
If the treasure were in the 3rd chest:
-Inscription on the 2nd chest (“The treasure is not in this chest”): TRUE (since it is in the 3rd)
-Inscription on the 3rd chest (“The treasure is not in the 1st chest”): TRUE (since it is in the 3rd, it is indeed not in the 1st)
-This also results in two true statements, so this possibility is ruled out as well.
If the treasure is in chest 2:
-Inscription on chest 1 (“The treasure is in this chest”): FALSE (because it is in chest 2)
-Inscription on chest 2 (“The treasure is not in this chest”): FALSE (because it is, in fact, in this very chest)
-Inscription on chest 3 (“The treasure is not in chest 1”): TRUE (since it is in chest 2, it is indeed not in chest 1)
