Sasha was visiting his grandmother. On Saturday, he got on a train and arrived home on Monday. Sasha noticed that on this Monday, the date matched the number of the carriage he was in, that the number of his seat in the carriage was less than the number of the carriage, and that on the Saturday when he got on the train, the date was greater than the number of the carriage. What were the numbers of the carriage and the seat?
Notice that the number of the same carriage on Saturday was less than the number, while on Monday it was equal to the number.

## Solution

Since the number of the same carriage on Saturday was less than the number, and on Monday it was equal to it, it is obvious that Saturday and Monday belong to different months, meaning Monday is the 1st or 2nd of the month, and the carriage number is 1 or 2. However, the carriage number cannot be 1, since the seat number is less than the carriage number. Therefore, Sasha traveled in carriage 2, seat 1.

## Answer

Carriage 2, seat 1.
