Answer 1

20gaini+7gsate=1878 kg
30gaini+7 gaste=2558 kg
-----------------------------------------
10 gaini=680
g=68 kg consuma o gaina

20x68+7 gaste=1878
7gaste=1878-1360
7gaste=518
g=74 kg consuma o gasca

Answer 2

20========7======1878
30========7======2558

600======210======56340
600======140======51160

210-140=70
56340-51160=5180
5180:70=74/gasca
74*7=518
1878-518=1360
1360:20=68/gaina

20*68========7*74=======1878
30*68========7*74=======2558
