А младше котлашанина, архангелогородец старше В. Б и ярославец сошли в Ярославле, а в и котлашанин в Вологде. Кто и где живет? -​

Answer 1

Ответ:

1. А и ярославец - врачи, и А младше котлашанина, следовательно, А - котлашанин.

2. Туляк и В - инженеры, но туляк не служил в армии, следовательно, В - участник боевых действий.

3. Д и мурманчанин - учителя, а туляк не служил в армии, поэтому Д не туляк, и он мурманчанин.

4. Архангелогородец старше В, а В - участник боевых действий, следовательно, Архангелогородец - В.

5. Теперь у нас остались Б и Е, которые также являются участниками боевых действий. Но они не могут быть ярославцем и мурманчанином (уже известные профессии), поэтому они - Д и мурманчанин. Б и ярославец сошли в Ярославле, так что Б - ярославец.

Итак, теперь мы знаем, кто и где живет:

- А - котлашанин.

- Б - ярославец. Они сошли в Ярославле.

- В - архангелогородец. Он старше Б. Они не сошли вместе.

- Г - туляк. Он не служил в армии.

- Д - мурманчанин. Он учитель. Они сошли в Вологде.

- Е - петербуржец. Он участник боевых действий.

The Problem

In a train compartment traveling from Moscow to Arkhangelsk, there were six passengers: a resident of Yaroslavl, a resident of Murmansk, a resident of Tula, a resident of St. Petersburg, a resident of Kotlas, and a resident of Arkhangelsk. Their surnames started with the letters A, B, C, D, E, and F. During the journey, they discovered the following information about each other: - A and the resident of Yaroslavl are doctors. - D and the resident of Murmansk are teachers. - The resident of Tula and C are engineers. - B and E are participants in military actions. - The resident of Tula did not serve in the army. - A is younger than the resident of Kotlas, and the resident of Arkhangelsk is older than C. - B and the resident of Yaroslavl got off the train in Yaroslavl, while D and the resident of Murmansk got off in Arkhangelsk. - The resident of Tula got off in Vologda.
