Problem 8.3. Four children were walking along an alley and decided to count the number of firs planted along it.

- Anya said: "There are a total of 15 firs along the alley."
- Borya said: "The number of firs is divisible by 11."
- Vера said: "There are definitely fewer than 25 firs."
- Gena said: "I am sure that their number is divisible by 22."

One boy and one girl were right, while the other two were wrong. How many firs grow along the alley?
