Answer 1

negre: 1200:100x10=120 masini
rosii: 1200:100x12=144 masini
albastre: 1200:100x15=180 masini
galbene : 1200:100x25=300 masini
albe: 1200:100x38=456 masini

Answer 2

10% masini negre = 1200*10/100=120 masini negre
12% masini rosii = 1200*12/100 = 144 masini rosii
15% masini albastre = 1200*15/100 = 12*15=180 masini albastre
25% masini galbene = 1200*25/100 = 1200/4 = 300 masini galbene
38% masini albe = 1200*38/100 =12*38 = 456 masini albe
Total = 120+144+180+300+456 = 1200 masini
