Question

In trei cutii sunt 63 bomboane.
Cate bomboane sunt in fiecare cutie,daca in prima sunt de 4 ori mai putine decat in a doua , iar in a treia sunt jumatate din a doua

Answer 1

Notam:
a = bomboane prima cutie
b = bomboane a 2-a cutie
c = bomboane a 3-a cutie

a+b+c = 63
a = b:4 => b = 4×a
c = b : 2
a |___|
b |___|___|___|___|
c |___|___|
avem 7 segmente egale = 63
63 :7 = 9 (un segment egal)
a = 9
b = 4×9 = 36
c = 2×9 = 18

Verificare:
9+36+18 = 63

9 bomboane in prima cutie
36 bomboane in a 2-a cutie
18 bomboane in a 3-a cutie
