Answer 2

70%×2000 = 7/10 × 2000 = 14000/10 = 1400 kg

50%×1400 = 1/2 × 1400 = 700 kg

Calitatea a III a

2000kg - 1400kg = 600 kg

Calitatea a II a

700 kg

Calitatea I

700 kg

30%×C = 90 kg =>3C/10 = 90 => 3C = 900 => C = 900/3 = 300 kg cartofi

(70%×x)×30% = 70 kg

7x/10×1/2 = 70 kg

7x/20 = 70 kg

7x = 1400 kg

x = 1400/7 kg

x = 200 kg
