Answer 3

I can answer your question in detail. Before the New Year, one of the five children could not wait for the holiday and bit off a piece of cake. Find out who it is. Masha - It's Vova or Olya Olya - It's not me and not Misha Kolya - In my opinion, one of the girls is lying, and the other is telling the truth. Misha - Kolya, you are wrong. Vova - Well, as always. Someone lied!

The answer is Olya. Here is how I solved it:

- Let's assume that each child can either tell the truth (T) or lie (L). - If Masha is telling the truth, then the culprit is either Vova or Olya. But then Olya contradicts Masha by saying it's not her. So Masha and Olya cannot both be telling the truth. - If Masha is lying, then the culprit is either Kolya or Misha. But then Olya agrees with Masha by saying it's not Misha. So Masha and Olya cannot both be lying. - Therefore, Masha and Olya have different truth values. One of them is telling the truth and the other is lying. - Kolya says that one of the girls is lying and the other is telling the truth, which is consistent with the previous conclusion. So Kolya is telling the truth. - Misha says that Kolya is wrong, which contradicts the previous conclusion. So Misha is lying. - Vova says that someone lied, which is true. So Vova is telling the truth. - Now we have the truth values of each child: Masha (L), Olya (T), Kolya (T), Misha (L), Vova (T). - Since Olya is telling the truth, it means that she is the culprit. She bit off a piece of cake and lied about it.Ответь+подробно.+Перед+Новым+Годом,+один+из+пяти+детей+не+мог+дождаться+праздника+и+откусил+пирога.+Выясните+кто+это?+Маша+-+Это+Вова+или+Оля+Оля+-+Это+не+я+и+не+Миша+Коля+-+По+-+моему,+одна+из+девочек+врет,+а+другая+говорит+правду.+Миша+-+Коля,+ты+ошибаешься.+Вова+-+Ну,+как+всегда.+Кто+то+сказал+неправду!
