Question

O cantitate de capsuni trebuie pusa in lazi.Daca in fiecare lada se pun cate 5 kg raman 180 kg.Daca se pun in fiecare lada cate 6 kg,raman 20 de lazi goale si o lada cu 2 kg
Cate lazi si cate kg de capsuni sunt?

Answer 1

n=numar de lazi.
k=total kilograme de capsuni.
Daca in fiecare lada se pun cate 5 kg, raman 180 kg
5n+180=k

Daca se pun in lazi cate 6 kg ,raman 20 lazi goale si o lada cu 2 kg

6(n-20)+2=k

=> 5n+180=6(n-20)+2
=> n=298 lazi

din:
5n+180=k
=> k=5*298+180
=>k = 1670 kg de capsuni.
