a+b+c=45

a>c de 3 ori

b<c de 2 ori

-------------------

a=? b=? c=?

a + b + c = 45
a > c de 3 ori --> a = 3c
b < c de 2 ori --> c = 2b
a = 3c --> a= 6b

6b + b + 2b = 45
9b = 45 --> c = 5
a = 3c --> a = 15
b = 45 - a - c
b = 45 - 15 - 5
b = 25

am aflat ca fiecare segment este 5
atunci a=5x6
a=30
b=5
c=5x2
c=10
