Răspuns :
I + II + III = 187087
I + II = 145373
II + III = 144931
187087 - 145373 = 41714 puncte a obtinut al III copil
187087 - 144931 = 42156 puncte a obtinut I copil
145373 - 42156 = 103217 puncte a obtinut al II copil
a+b+c = 187.087
a+b = 145.373
b+c = 144.931
c + 187.087 = 145.373, c = 187.087 - 145.373 = 41.714
a + 144.931 = 187.087, a = 187.087 - 144.931 = 42.156
42.156 + b = 145.373, b = 145.373 - 42.156 = 103.217
a+b = 145.373
b+c = 144.931
c + 187.087 = 145.373, c = 187.087 - 145.373 = 41.714
a + 144.931 = 187.087, a = 187.087 - 144.931 = 42.156
42.156 + b = 145.373, b = 145.373 - 42.156 = 103.217
