Given Information:
- There are five students - P, Q, R, S, and T.
- Only one student has copied in the exam.
- Statements:
- P: R has copied in the exam.
- Q: S has copied in the exam.
- R: P did not copy in the exam.
- S: Only one of us is telling the truth.
- T: R is telling the truth.
- S never lies.
Analysis:
We need to determine the person who has copied in the exam based on the given statements.
Solution:
Let's evaluate each statement and analyze the possibilities.
Statement of P: R has copied in the exam.
- If P is telling the truth, then R has copied.
- If P is lying, then R may or may not have copied.
Statement of Q: S has copied in the exam.
- If Q is telling the truth, then S has copied.
- If Q is lying, then S may or may not have copied.
Statement of R: P did not copy in the exam.
- If R is telling the truth, then P did not copy.
- If R is lying, then P may or may not have copied.
Statement of S: Only one of us is telling the truth.
- Since S never lies, this statement is true.
- This means only one student is telling the truth, and the remaining students are lying.
Statement of T: R is telling the truth.
- If T is telling the truth, then R is telling the truth.
- If T is lying, then R may or may not be telling the truth.
Analysis of Statements:
1. If P is telling the truth and R has copied, then P is also telling the truth. But this contradicts the statement of S, which states that only one person is telling the truth. Therefore, P is lying.
2. If Q is telling the truth and S has copied, then Q is also telling the truth. But this contradicts the statement of S, which states that only one person is telling the truth. Therefore, Q is lying.
3. If R is telling the truth and P did not copy, then R is also telling the truth. But this contradicts the statement of S, which states that only one person is telling the truth. Therefore, R is lying.
4. If T is telling the truth and R is telling the truth, then both T and R are telling the truth. This is consistent with the statement of S, which states that only one person is telling the truth. Therefore, T is telling the truth.
Deduction:
From the above analysis:
- P, Q, and R are lying.
- T is telling the truth.
Conclusion:
Since only one person has copied in the exam, and P, Q, and R are lying, the person who has copied in the exam is P.
- There are five students - P, Q, R, S, and T.
- Only one student has copied in the exam.
- Statements:
- P: R has copied in the exam.
- Q: S has copied in the exam.
- R: P did not copy in the exam.
- S: Only one of us is telling the truth.
- T: R is telling the truth.
- S never lies.
Analysis:
We need to determine the person who has copied in the exam based on the given statements.
Solution:
Let's evaluate each statement and analyze the possibilities.
Statement of P: R has copied in the exam.
- If P is telling the truth, then R has copied.
- If P is lying, then R may or may not have copied.
Statement of Q: S has copied in the exam.
- If Q is telling the truth, then S has copied.
- If Q is lying, then S may or may not have copied.
Statement of R: P did not copy in the exam.
- If R is telling the truth, then P did not copy.
- If R is lying, then P may or may not have copied.
Statement of S: Only one of us is telling the truth.
- Since S never lies, this statement is true.
- This means only one student is telling the truth, and the remaining students are lying.
Statement of T: R is telling the truth.
- If T is telling the truth, then R is telling the truth.
- If T is lying, then R may or may not be telling the truth.
Analysis of Statements:
1. If P is telling the truth and R has copied, then P is also telling the truth. But this contradicts the statement of S, which states that only one person is telling the truth. Therefore, P is lying.
2. If Q is telling the truth and S has copied, then Q is also telling the truth. But this contradicts the statement of S, which states that only one person is telling the truth. Therefore, Q is lying.
3. If R is telling the truth and P did not copy, then R is also telling the truth. But this contradicts the statement of S, which states that only one person is telling the truth. Therefore, R is lying.
4. If T is telling the truth and R is telling the truth, then both T and R are telling the truth. This is consistent with the statement of S, which states that only one person is telling the truth. Therefore, T is telling the truth.
Deduction:
From the above analysis:
- P, Q, and R are lying.
- T is telling the truth.
Conclusion:
Since only one person has copied in the exam, and P, Q, and R are lying, the person who has copied in the exam is P.
