Notam lazile cu a,b si c, ai avem :
b-b*1/5=a+b*1/5+c*1/3=c-c*1/3
⇒b-b*2/5=a+c*1/3
b*3/5=a+c*1/3
a=b*3/5-c*1/3
⇒a+b*1/5+c*1/3=c-c*1/3
a+b*1/5=c*1/3
a=c*1/3-b*1/5
b*3/5-c*1/3=c*1/3-b*1/5
b*3/5+b*1/5=c*1/3+c*1/3
b*4/5=c*2/3
12*b=10*c
c=b*12/10=6/5
a=c*1/3-b*1/5=b*6/5*1/3-b*1/5=b*2/5-b*1/5
a=b*1/5
De vreme ce problema nu iti da nici o cantitate de referinta exprimata in kg , Din aceste procentaje
daca a=10kg => b=5*10=50kg =>c=50*6/5=60kg
Si de aici pot fi multiplii ai acestor numere:
10-50-60
20-100-120
40-150-180
etc
