Question

la ferma avicola din Bardar erau 2380 de fazani si prepelite . Cite pasari de fiecare fel erau stiind ca prepelite erau cu 380 mai multe ?

Answer 1

f+p=2380pasari
p=f+380

f+f+380=2380
2f=2380-380
2f=2000
f=2000:2
f=1000 fazani
p=1000+380
p=1380 prepelite

1000+1380=2380 pasari in total
