Question

La o ferma sunt 7963 de gaini,rate si gaste.Gaini si rate sunt 5644,iar rate si gaste sunt 4050.Cate pasari de fiecare fel sunt la ferma?

Answer 1

daca adunam 4050+ 5644=9694 - aste is gaini giste si dublu ratelor
rezulta ca 9694-7963=1731-sunt rate
5644-1731=3913 -sunt gaini
4050-1731=2319-sunt giste

Answer 2

g+r+gaste=7.963
g+r=5.644 =>putem afla gastele
r+gaste=4.050=>putem afla gainile

gaste=7.963-5.644
gaste=2.321

gaini=7.963-4.050
gaini=3.913

rate=5.644-3.913
rate=1.731
