1 Varianta A
a = fete si b = baieti
a = |----|----| [tex] \left \{ {{=99} \atop {}} \right. [/tex]
b = |----|
99 : 3 = 33 baieti
33 x 2 = 66 fete
Varianta B
a = fete b = baieti
a + b = 99
a = b x 2
b x 2 + b = 99
2 b + b = 99
3 b = 99
b = 99 : 3 = 33
a = 33 x 2 = 66
2
Balaurul = B Mama = M
B + 25 = M
M = 6 B
B + 25 = 6 B
6 B = 25
B = 25 : 5
B = 5
M = 5 x 6 = 30
