I concurent - x + 1 puncte
II concurent - x puncte
III concurent - x - 1/2 puncte
x + 1 + x + x - 1/2 = 35
3x + 1/2 = 35 /x2
6x + 1 = 70
6x = 69
x = 69 : 6
x = 11,5
I concurent = 11,5 +1 = 12,5 puncte
II concurent = 11,5 puncte
III concurent = 11,5 - 1/2 = 11,5 - 0,5 = 11 puncte
12,5 + 11,5 + 11 =35
