Răspuns :
a+v+r=10000
a=299 (beculete albastre)
v=299x2=598 ( beculete verzi)
299+598+r=10000
897+r=10000
r=10000-897
r=9103 ( beculete rosii )
V: 299+598+9103=10000
a=299 (beculete albastre)
v=299x2=598 ( beculete verzi)
299+598+r=10000
897+r=10000
r=10000-897
r=9103 ( beculete rosii )
V: 299+598+9103=10000
1) cate beculete verzi s-au folosit?
299+299=598
2) cate beculete rosii s-au folosit?
10000-(299+598)=9103
299+299=598
2) cate beculete rosii s-au folosit?
10000-(299+598)=9103
