Câu hỏi:
Once upon a time, in a temple, there were three deities: Truth, Lie and Wisdom. The Truth Deity always told the truth. The Lie Deity always told the lie. The Wisdom Deity sometimes told the truth, sometimes told the lie. Unfortunately, those three deities looked exactly the same, so that no one could distinguish them. One day, a sage came by and he differentiated them by the following trick: He asked the deity sitting on the left: "Who is the middle deity?"- "Truth", said the deity. He asked the deity sitting in the middle: "Who are you?"- "Wisdom", replied the deity. He asked the deity sitting on the right: "Who is the middle deitie?"- "Lie", the deity answered.
Đáp án:
The left deity is Wisdom; the middle one is Lie, and the right one is Truth. Explain: The left deity (L) said that the middle one (M) is Truth; therefore, L cannot be Truth (because there cannot be two Truth Deities!). M said he was Wisdom; therefore, he cannot be Truth. Thus, R is Truth. According to him, M is Lie and as a result, L is Wisdom.
