Answer 1

15 faina + 10 cartofi = 1050 kg
5 faina +10 faina + 5 cartofi = 650 kg => 15 faina +5 cartofi = 650 kg
15 faina +10 cartofi = 1050 kg 15 faina + 5 cartofi = 650 kg =>. 5cartofi= 1050-650 = 400 kg
1 cartof = 400 : 5= 80 kg
15 faina + 10 cartofi = 1050 kg
15 faina + 80 × 10 = 800 kg = 1050
15 faina = 1050 - 800 = 250 kg
5 faina = 250 : 5 = 50 kg
1 faina = 50 : 5 = 10 kg

1 faina = 10 kg
1 cartofi = 80 kg
