Question

Intr-o curte sunt 63 de pasari :rate ,gaste si gaini . Unei gaste ii corespund 3 gaini ,iar la 2 gaste corespunde o rata.
Cate pasari de fiecare fel sunt?

Answer 1

Formam grupe de pasari:

3gaini- 1gasca

3gaini- 1gasca

        1 rata

avem 9 pasari

63/9=7

7*6=42 ( gaini)

7*2=14 (gaste)

7*1=7 (rate)

Verif 42+14+7=63 (pasari)
