Answer 3

Solution:

To solve this riddle, we need to analyze the statements made by the three friends and find the correct names.

1. First Friend's Statement: - The first friend said, "My name is Marina." - Let's denote this statement as A.

2. Second Friend's Statement: - The second friend said, "My name is Katya." - Let's denote this statement as B.

3. Third Friend's Statement: - The third friend said, "My name is Marina or Lena." - Let's denote this statement as C.

Now, let's analyze the statements to find the correct names of the three friends.

Analysis:

- If the first friend's statement (A) is true, then her name is Marina. - If the second friend's statement (B) is true, then her name is Katya. - If the third friend's statement (C) is true, then her name is Marina or Lena.

However, we know that all three friends lied about their names. Therefore, we can conclude the following:

- If the first friend's statement (A) is false, then her name is not Marina. - If the second friend's statement (B) is false, then her name is not Katya. - If the third friend's statement (C) is false, then her name is neither Marina nor Lena.

Conclusion:

From the analysis, we can deduce the following: - The first friend's name is not Marina. - The second friend's name is not Katya. - The third friend's name is neither Marina nor Lena.

Given that the names of all three friends have been correctly stated, we can conclude that: - The first friend's name is Lena. - The second friend's name is Marina. - The third friend's name is Katya.

Therefore, the names of the three friends are: - First Friend: Lena - Second Friend: Marina - Third Friend: Katya
