Buna!
Nu stiu daca vrei prin metoda figurativa; dar cred ca da...
1 ____/__23t_/ } 85t
2 ____/ }
3 ____/____/____/
4 ____/____/__23t_/__23t_/
85t-23t=62t
62t:2=31t (silozul 2)
31t+23t=54t(silozul 1)
31t×3=93t (silozul 3)
54tx2=108t(silozul 4)
Deci...
31t+54t+93t+108t=286t
(in toate 4 silozuri)
Succes! :3
