Met 1:9×4=36kg zahar se consuma dupa 4 zile. 6×4=24 kg de orez se consuma dupa 4 zile. 50-36=14 kg zahar raman. 40-24=16 kg orez raman. 14kg+16kg=30kg raman in total. Met2 4×9+4×6=36+24=60kg se consuma dupa 4 zile de orez si zahar. 40+50=90kg au fost aduse. 90-60=30 kg mai raman

Answer 2

6 x4 = 24 kg
cate kg raman?
40 - 24 = 16 kg

14 + 16 = 30 kg
