Answer 1

1. 
a |--x--|...............200............|
b |--x--||--x--||--x--||--x--||--x--|

observam ca 4 segmente au valoare 200. Aflam cat are un segment:
4*x=200
x=200:4
x=50 => primul segment (a) = 50
b=50x5=250

Verificare: 250:5 = 50 ADEVARAT si 250-50 = 200 ADEVARAT

2.
a |......x......|
b |......x......||......x......|                  } 867
c |......x......||......x......|.2.|

Avem 5 segmente egale si inca 2
5x+2=867
5x=867-2
5x=865
x=865:5
x=173

Asadar a=173
b=173+173 = 346
c=346+2 = 348
