It is from Gazeta Matematica grade 10 and the solutions can be sent until April. In addition, this problem has the chance to be selected for the District Phase Mathematical Olympiad
One problema from Gazeta Matematica will be on the District Phase of Math Olympiad.This is why some people post the problems online to get solutions...
Edit: All the problems posted by the OP are from Gazeta Mathematica.
