Stiind ca fiecare punga are 3 kg si in un an o cantina foloseste 4kg pe luna afla cate kg faina raman in camara dupa un an.dar dupa 4ani. ?

Answer 1

1)a+b+c=347
a+c=235;a=235-c
b+c=207; b=207-c
235-c+207-c+c=347
c=95; a=140; b=112
2) 11x112=1232
3) nr total de pungi=17x9=153
nr total kg faina = 153x4=612 kg
un an= 12 luni
faina consumata intr-un an= 4x12=48 kg
faina ramasa dupa un an= 612-48=564 kg
faina consumata in 4ani = 4x48=192 kg
faina ramasa dupa 4 ani=612-192=420 kg
