O firma are 120 de angajati .Determinati numarul barbatilor angajati in firma,stiind ca numarul femeilor reprezinta 20% din numarul barbatilor....... Va rog vreau raspunsul repede si rezolvarea completa

Answer 1

f+b=120
f=20%·xb=bx20/100=simplif=b/5
deci f=b/5
b/5+b=120
(b+5b)/5=120
6b/5=120
6b=120x5
b=600/6
b=100 barbati
f=b/5=100/5=20
f=20 femei

Answer 2

X+Y=120
X=20/100*Y
1/5*Y+Y=120
1/5Y+5/5Y=120
6/5Y=120
Y=100
X=20/100*100
X=20
