pui=760
III > II de 2 ori
I > III de 2 ori + 60
------------------------------------
II /---/(aste fiind segmentele)
III /---/---/ }760
I /---/---/---/---/-------/
760-60= 700 (pui ar fi fost daca nu ar fi fost cei 60)
700:7=100 (pui sunt in II)
100x2=200 (pui in III)
200x2+60= 460 (pui in I)
Proba: 100+200+460=760
