O singura cantarire

Proposed by MaseruOffline
(3 comments)11.960 times displayed

Avem 10 saci plini cu monede, fiecare moneda cantareste 10 grame.
Un singur sac dintre cei 10 este plin cu monede false. Toate monedele din acest sac sunt false, o moneda falsa fiind mai grea decat una normala cu 1 gram.
Avand la dispozitie un cantar foarte exact, aflati sacul cu monede false dintr-o singura cantarire.
