|--------------------------------------------------------------------------------------------------------------|   =750

|-------------------|--30--| Irina -i

|-------------------|   Radu -r
|-------------------||-------------------||-------------------||-------------------| Marius- m

le facem pe toate in functie de radu
(r+30)+r+(r+r+r+r)=750

6 * radu=750-30
6 * radu=720
radu=720:6
radu=120

deci fiecare segment din alea inseamna  120

irina=120+30=150

marius=750-(120+150)
marius=750-270
marius=480
sau marius=120+120+120+120=480

Aflam suma partilor egale :
 750-30=720
720:6=120 Radu
 120+30=150 Irina
 120x4=480 Marius
Verificare : 480+150+120=750
