always three people speak truth only whos guess?

To determine who's telling the truth among the three people, you can follow these steps:

1. Ask each person a question that you already know the answer to. This will allow you to verify whether each person is telling the truth or not.

2. After asking the question, compare each person's response to the known correct answer. If their statements align with the truth, mark them as potential truth-tellers.

3. Repeat this process for different questions, making note of the consistency of each person's answers. The individuals who consistently provide accurate information are likely to be the truthful ones.

4. Compare the consistent answers across the questions. Identify the three individuals whose statements align with the truth in all instances. These are the people who always speak truth.

By using this method, you can determine the three individuals who consistently tell the truth among the group.
