Răspuns :
a + b + c = 724
a /----/
b /----/----/+10
c /----/----/----/----/
724 - 10 = 714
714 : 7 = 102 (valoarea unui segment egal)
a = 102
b = 2 × 102 + 10 = 204 + 10 = 214
c = 4 × 102 = 408
verificam:
102 + 214 + 408 = 724
a = 102
b = 214
c = 408
a /----/
b /----/----/+10
c /----/----/----/----/
