## Task 1 - 080911

A FDJ meeting was so well attended that exactly 75 percent of the FDJ members found seats. Therefore, it was decided to hold a second meeting in another room. 150 of the young friends went there. The rest remained in the first room. As a result, exactly 5 seats were left free in this room.

Determine the total number of young friends who appeared at the originally scheduled event!
According to the problem statement, $0.25 \cdot x + 5 = 150$. Therefore, 580 young people attended, of which 435 were initially seated before 150 left.
