Problem Analysis

We have three individuals: A, B, and C. One of them is a liar, one is a knight (always tells the truth), and one is a regular person. Each person knows who they are and they make the following statements: - A: "I am a regular person." - B: "A told the truth." - C: "I am not a regular person."

We need to determine who is the knight, who is the liar, and who is the regular person.

Solution

Let's analyze each statement and see if we can determine the identities of A, B, and C.

Statement A: "I am a regular person." - If A is the knight, then the statement is true, which means A is a regular person. - If A is the liar, then the statement is false, which means A is not a regular person.

Statement B: "A told the truth." - If B is the knight, then the statement is true, which means A told the truth. This implies that A is the regular person. - If B is the liar, then the statement is false, which means A did not tell the truth. This implies that A is not the regular person.

Statement C: "I am not a regular person." - If C is the knight, then the statement is true, which means C is not a regular person. - If C is the liar, then the statement is false, which means C is a regular person.

Based on the analysis, we can conclude the following: - A is the regular person. - B is the knight. - C is the liar.

Conclusion

Based on the statements made by A, B, and C, we can determine that A is the regular person, B is the knight, and C is the liar.
