Four children were walking along an alley and decided to count the number of fir trees planted along it.

- Anya said: "There are 15 fir trees along the alley."
- Borya said: "The number of fir trees is divisible by 11."
- Vera said: "The number of fir trees is definitely less than 25."
- Gena said: "I am sure that the number of fir trees is divisible by 22."

One boy and one girl told the truth, while the other two were mistaken. How many fir trees are growing along the alley?
