Question

O firma are 120 de angajati. Determinati numarul barbatilor angajati in firma, stiind ca numarul femeilor reprezinta 20% din numarul barbatilor

Answer 1

Femei-20/100*b
Barbati-b
20/100*b+b=120
1.2b=120
b=100 barbati
femei:120-100=20
raspuns:20-f,100-b

Answer 2

Fie b-barbatii
f-femeile
b+f = 120
f= 20/100 * b
20/100 *b + b =120
20b + 100b = 12000
120b =12000
b=100
f=20
