Question

Teodora are in gradina 40 de flori: trandafiri, margarete si irisi.Daca le ar grupa , la 4 trandafiri ar corespunde 2 margarete, iar la o margareta corespund 2 irisi.cate flori sunt de fiecare fel?

Answer 1

t+m+i=40
4t=2m=>4t=4i I:4=>t=i
m=2i

i+2i+i=40
4i=40=>i=40:4=>i=10 irisi
m=2x10=20 margarete
t=i=10 trandafiri
