Question

la o florarie s au primit de dimineata 50 de trandafiri albi,rosii si galbeni.cati trandafiri rosii s au adus,stiind ca la 3 trandafiri albi s au primit 5 tramdafiri rosii si doi galbeni?

Answer 1

3 + 2 +5 =10 flori intr-un buchet
50 : 10 = 5 ; cite 5 buchete
Trandafiri alb = 3 x 5 = 15
Trandafiri rosii = 5 x 5 = 25
Trandafiri galbeni = 2 x 5 = 10

Answer 2

n(3a+5r+2g)=50
n∈D50={1,2,5,10,25,50} multimea divizorilor lui 50
n*10flori=50
n=5
Deci avem
3*5 albi= 15
5*5 rosii=25
2*5 galbeni=10
