Răspuns :
A + I = 780
A + T = 960
I + T = 820
2A + 2 I + 2T = 780 + 960 + 820 = 2560
2 ( A + I + T ) = 2560
A + I + T = 2560 : 2
A + I + T = 1280
780 + T = 1280
T = 1280 - 780
T = 500 ( ARE TEODORA)
A + T = 960
A + 500 = 960
A = 960 - 500
A = 460 ( ARE ANA)
A + I = 780
460 + I = 780
I = 780 - 460
I = 320 ( ARE IRINA)

320 + 460 + 500 = 1280
