Question

Un pahar si o sticla cantaresc cat o cana , iar sticla respectiva cantareste cat paharul si o farfurie . Stiind ca doua canu cantaresc cat trei farfurii , aflati cate pahare cantaresc o sticla.

Answer 1

pahar = P
sticla = S
cana = C
farfurie = F

P + S = C
S = P + F
2 x C = 3 x F
? P = 1 S

C = P + S
C = P + P + F
C = 2 x P + F
2 C = 2 x ( 2 x P + F )
2 C = 4 P + 2 x F

3 X F = 4 x P + 2 x F
F = 4 x P

S = P + F
S = P + 4 x P
S = 5 x P

Raspuns : S = 5 x P
