$\huge\bf\underline{\underline{\pink {\{QUESTION}\}}}$

Logical Reasoning Question:

Police had arrested four criminals P, Q, R and S.

→ P says Q committed crime
→ Q says S committed crime
→ R says “I didn’t do it”
→ S says what Q said about me is false.

There is only one criminal and also only one of the above statements is correct. Who among the four committed the crime? Also provide suitable explanation in support of your answer.​

Answer 1

Explanation:

We'll consider each person to be the criminal.

• If P is the criminal, P is lying, Q is lying, R is saying the truth, and S is saying the truth.
• If Q is the criminal, P is telling the truth, Q is lying, R and S both are telling the truth.
• If S is the criminal, P and S are lying while Q and R are saying the truth.
• But, if R is the criminal, P, Q and R are all lying, while only S speaks the truth.

Since it is already given that only one of the four statements is correct, it is only logical that R is the criminal.

Answer: R

Answer 2

Answer:

R is the one who committed crime.
