Question

in 3 magazi se afla 936 tone de porumb .in prima magazie se afla cu 36 de tone mai putin porumb decat in a doua iar in a 3 magazie cat jumatea din cantitatea de porumb aflata in prima magazie .ce cantitate de porumb in fiecare magazie

Answer 1

notam: a,b,c -cele trei magazii
a+b+c =936
b=a+36⇒b=2c+36
a=2c
inlocuim in prima relatie si obtinem:
2c+2c+36+c=936
5c +36=936
5c=936-36
5c=900
c=900:5
c=180
a=2*180
a=360
b=360+36
b=396

Verificare:360+396+180=756+180=936
