Question

Ребята обсуждают предстоящую контрольную работу по математике. "Контрольная будет в понедельник или четверг"-сказала Лена. "Во вторник или пятницу"-сказал Юра. "Точно-после среды"-сказала Таня. "В понедельник"-сказал Саша. "Все вы не правы"-сказала Наташа. Оказалось, что мальчики и девочки ошиблись одинаковое число раз. Так когда де будет контрольная, если известно, что она будет одна? {Я думаю, что в субботу, но сильно сомневаюсь}

Answer 1

Если методом исключения из пяти дней, то в среду

Answer 2

Я думаю,что будет в пятницу

Answer 3

Analysis:

The students are discussing the upcoming math test and trying to determine the day it will take place. Each student provides a different day, and Natasha claims that everyone is wrong. The task is to determine the correct day for the test.

Solution:

To solve this problem, let's analyze the statements made by each student:

- Lena says the test will be on Monday or Thursday. - Yura says the test will be on Tuesday or Friday. - Tanya says the test will be after Wednesday. - Sasha says the test will be on Monday. - Natasha claims that everyone is wrong.

From these statements, we can deduce the following:

- Lena and Yura's statements contradict each other, as they both cannot be correct. - Tanya's statement implies that the test will not be on Monday or Tuesday, as it will be after Wednesday. - Sasha's statement contradicts Lena's statement, as they both cannot be correct. - Natasha claims that everyone is wrong, which means that none of the previous statements are correct.

Based on this analysis, we can conclude that none of the provided days (Monday, Tuesday, Thursday, or Friday) are correct. Therefore, we need to consider other possibilities.

Possible Solutions:

Since none of the students' statements are correct, we need to explore other options. Here are a few possibilities:

1. The test could be on Wednesday, as Tanya's statement implies that it will be after Wednesday. 2. The test could be on Saturday, as you suggested in your question.

Without further information, it is difficult to determine the exact day of the test. However, based on the given information, Wednesday or Saturday seem to be the most likely options.

Please note that this is a logical deduction based on the information provided. The actual day of the test may depend on additional factors or context that are not mentioned in the given conversation.

I hope this helps! Let me know if you have any further questions.
