Răspuns :
/___/ → curcile
/___/___/___/___/___/ → gainile
/___/ + 30 → ratele
450 - 30 = 420 ( egalarea segmentelor )
420 : 7 = 60 ( curcile - un singur segment )
60 × 5 = 300 ( gaini, de 5 ori mai multe )
60 + 30 = 90 ( ratele )
/__/__/__/__/__/ gainile
/__/ curcile
/__/+30 ratele
In total 450 pasari
Egalam suma segmentelor
450-30=420
5+1+1=7 parti egale
420:7=60 un segment ( nr curcilor)
60×5=300 nr gainilor
60+30=90 nr ratelor
Verificare 300+60+90=450 pasari
