Answer 1

ms=md+m apa
c=md*100/ms
md=c*ms/100
ms=md*100/c
c*ms=md*100
m apa=ms-md
primul rand : ms=100g
c=20*100/100=20%
rand 2: m apa=185 g
c=15*100/200=15*2=30%
rand 3:md=70*350/100=7*35=245g
m apa=350-245=105g
rand 4:md=30g ( ms-mapa)
c=30*100/200=15
rand 5:1kg=1000g
md=25*1000/100=250g
mapa=750g
rand 6:ms=2*100/40=5 g
m apa=3g
rand 8:mapa=210 g
c=40*100/250=16 g
rand 7:ms=700+md
30*(700+md)=md*100
21000+30md=100md
21000=70md
ms=300g
ms=1000g
