Explicație pas cu pas:
1.
a + b + c = 22 3/4 m
a + b = 12 1/4 m
deci c = 22 3/4 - 12 1/4 = 10 2/4 m
a + c = 13 3/4 m
deci b = 22 3/4 - 13 3/4 = 9 m
a = 12 1/4 - b = 12 1/4 - 9 = 3 1/4 m

Portocale vandute
2370 x 2/3 = 1580 kg
Banane vandute
2640 x 3/4 = 1980 kg
Bani incasati
1580 x 4 + 1980 x 6 = 6320 + 11880 = 18200 lei
