Question

Год назад с нашего двора первый раз в первый класс пошли 5 мальчиков. Их имена: Петя, Коля, Ваня, Гена и Миша. Получилось так, что все пятеро попали в разные классы: один в класс “А”, другой – в “Б”, третий – в “В”, четвертый - в “Г”, пятый – в “Д”. Каждому из ребят досталась в качестве классного руководителя добрая учительница: Лидия Михайловна, Елена Анатольевна. Екатерина Кирилловна. Татьяна Григорьевна и Виктория Николаевна. Дети учились прекрасно, напротив их фамилий ( Анисин, Белов, Кукушкин, Степанов и Харитонов) всегда были практически одни пятерки. Определите имя, фамилию, класс и учительницу для каждого из первоклашек, если известно, что: 1. Ваня учится у Татьяны Григорьевны и его фамилия не Степанов. 2. В классе “Д” преподает не Екатерина Кирилловна. 3. Коля учится в классе “Б”. Он старше на 1 месяц, чем Белов, и младше на 12 дней, чем тот, кто учится у Татьяны Григорьевны. 4. Елена Анатольевна преподает в классе “Г” и у нее нет ученика по фамилии Белов. 5. Харитонов Гена дружит с Петей и с тем, кто ходит в класс “А”. 6. Кукушкин учится в классе “А”. Его учительница не Лидия Михайловна и не Екатерина Кирилловна. 7. Анисин учится в классе “В” и его имя не Петя и не Миша.

Problem Analysis

We are given a problem where five boys named Petya, Kolya, Vanya, Gena, and Misha have joined different classes in their first year of school. We also know the names of their teachers. We need to determine the name, surname, class, and teacher for each of the boys based on the given clues.

Clue Analysis

Let's analyze the given clues one by one:

1. Vanya is not studying with Tatiana Grigorievna, and his surname is not Stepanov. 2. Ekaterina Kirillovna is not teaching in class "D". 3. Kolya is studying in class "B". He is older than Belov by 1 month and younger than the student studying with Tatiana Grigorievna by 12 days. 4. Elena Anatolyevna is teaching in class "G", and there is no student with the surname Belov in her class. 5. Gena Khritonov is friends with Petya and the student in class "A". 6. Kukushkin is studying in class "A". His teacher is neither Lidia Mikhaylovna nor Ekaterina Kirillovna. 7. Anisin is studying in class "V", and his name is neither Petya nor Misha.

Solution

Based on the given clues, we can deduce the following information:

1. Vanya's surname is not Stepanov, and he is not studying with Tatiana Grigorievna. 2. Ekaterina Kirillovna is not teaching in class "D". 3. Kolya is studying in class "B". He is older than Belov by 1 month and younger than the student studying with Tatiana Grigorievna by 12 days. 4. Elena Anatolyevna is teaching in class "G", and there is no student with the surname Belov in her class. 5. Gena Khritonov is friends with Petya and the student in class "A". 6. Kukushkin is studying in class "A". His teacher is neither Lidia Mikhaylovna nor Ekaterina Kirillovna. 7. Anisin is studying in class "V", and his name is neither Petya nor Misha.

Let's use this information to solve the problem step by step:

1. From clue 1, we know that Vanya's surname is not Stepanov and he is not studying with Tatiana Grigorievna. 2. From clue 2, we know that Ekaterina Kirillovna is not teaching in class "D". 3. From clue 3, we know that Kolya is studying in class "B" and he is older than Belov by 1 month and younger than the student studying with Tatiana Grigorievna by 12 days. 4. From clue 4, we know that Elena Anatolyevna is teaching in class "G" and there is no student with the surname Belov in her class. 5. From clue 5, we know that Gena Khritonov is friends with Petya and the student in class "A". 6. From clue 6, we know that Kukushkin is studying in class "A" and his teacher is neither Lidia Mikhaylovna nor Ekaterina Kirillovna. 7. From clue 7, we know that Anisin is studying in class "V" and his name is neither Petya nor Misha.

Based on this information, we can deduce the following:

- Vanya's surname is not Stepanov, and he is not studying with Tatiana Grigorievna. - Ekaterina Kirillovna is not teaching in class "D". - Kolya is studying in class "B" and is older than Belov by 1 month and younger than the student studying with Tatiana Grigorievna by 12 days. - Elena Anatolyevna is teaching in class "G", and there is no student with the surname Belov in her class. - Gena Khritonov is friends with Petya and the student in class "A". - Kukushkin is studying in class "A", and his teacher is neither Lidia Mikhaylovna nor Ekaterina Kirillovna. - Anisin is studying in class "V", and his name is neither Petya nor Misha.

Let's summarize the information we have so far:

| Boy | Surname | Class | Teacher | |-------|-----------|-------|---------------------| | Vanya | Not known | Not known | Not Tatiana Grigorievna | | Kolya | Not known | B | Not known | | Gena | Not known | A | Not known | | Petya | Not known | Not known | Not known | | Misha | Not known | Not known | Not known |

Now let's analyze the remaining clues:

1. Vanya is not studying with Tatiana Grigorievna, and his surname is not Stepanov. - This clue tells us that Vanya's surname is not Stepanov and he is not studying with Tatiana Grigorievna. - We already know that Vanya is not studying with Tatiana Grigorievna, so we can conclude that his surname is not Stepanov. - Therefore, Vanya's surname is not Stepanov.

2. Ekaterina Kirillovna is not teaching in class "D". - This clue tells us that Ekaterina Kirillovna is not teaching in class "D". - We don't have any information about Ekaterina Kirillovna's class yet, so we cannot determine her class based on this clue.

3. Kolya is studying in class "B". He is older than Belov by 1 month and younger than the student studying with Tatiana Grigorievna by 12 days. - This clue tells us that Kolya is studying in class "B" and he is older than Belov by 1 month and younger than the student studying with Tatiana Grigorievna by 12 days. - We don't have any information about Belov or the student studying with Tatiana Grigorievna yet, so we cannot determine Kolya's surname or the name of the student studying with Tatiana Grigorievna based on this clue.

4. Elena Anatolyevna is teaching in class "G", and there is no student with the surname Belov in her class. - This clue tells us that Elena Anatolyevna is teaching in class "G" and there is no student with the surname Belov in her class. - We don't have any information about Belov yet, so we cannot determine Elena Anatolyevna's student's surname based on this clue.

5. Gena Khritonov is friends with Petya and the student in class "A". - This clue tells us that Gena Khritonov is friends with Petya and the student in class "A". - We don't have any information about Petya or the student in class "A" yet, so we cannot determine Gena Khritonov's surname or the name of the student in class "A" based on this clue.

6. Kukushkin is studying in class "A". His teacher is neither Lidia Mikhaylovna nor Ekaterina Kirillovna. - This clue tells us that Kukushkin is studying in class "A" and his teacher is neither Lidia Mikhaylovna nor Ekaterina Kirillovna. - We don't have any information about Kukushkin's surname yet, so we cannot determine his surname based on this clue. - We also don't have any information about Ekaterina Kirillovna's class yet, so we cannot determine her class based on this clue.

7. Anisin is studying in class "V", and his name is neither Petya nor Misha. - This clue tells us that Anisin is studying in class "V" and his name is neither Petya nor Misha. - We don't have any information about Anisin's surname yet, so we cannot determine his surname based on this clue.

Based on the given information and clues, we can only determine that Vanya's surname is not Stepanov. We don't have enough information to determine the surnames, classes, or teachers for the other boys.

Therefore, the only information we can determine is:

| Boy | Surname | Class | Teacher | |-------|-----------|-------|---------------------| | Vanya | Not Stepanov | Not known | Not Tatiana Grigorievna |

Unfortunately, we cannot determine the names, surnames, classes, or teachers for the other boys based on the given information and clues.
