Question

In trei silozuri sunt 32t cartofi.In primele doua sunt 28360kg,iar in ultimele doua sunt 16530kg.Cate kg de cartofi sunt in fiecare siloz?

Answer 1

32t=32000 kg
a+b+c=32000     
a+b=28360
b+c=16530
28360+c=32000 => c=32000-28360=3640 kg (in al treilea siloz)
a+16530=32000 => a=32000-16530=15470kg (in primul siloz)
15470+b=28360=> b=28360-15470= 12890kg (al doilea siloz)
