Răspuns :
e + v + d = 217
e + v = 158
v + d = 144
158 + d = 217
d = 217 -158 = 59 cuburi a folosit Daria
v + d = 144
v+59 = 144
v = 144 - 59 = 85 cuburi a folosit Victor
e + v + d = 217
e + 85 + 59 = 217
e = 73 cuburi a folosit Ema
verificare - 73 + 85 + 59 = 217
e + v = 158
v + d = 144
158 + d = 217
d = 217 -158 = 59 cuburi a folosit Daria
v + d = 144
v+59 = 144
v = 144 - 59 = 85 cuburi a folosit Victor
e + v + d = 217
e + 85 + 59 = 217
e = 73 cuburi a folosit Ema
verificare - 73 + 85 + 59 = 217
deci Ema a folosit 73 cuburi
Victor a folosit 85 cuburi
Daria a folosit 59 cuburi
Victor a folosit 85 cuburi
Daria a folosit 59 cuburi
