Avem un tren cu 10 vagoane.
Fiecare vagon este umplut cu un numar egal, dar nestiut de bile.
9 vagoane au bilele de cate 1 kilogram, iar 1 vagon are bilele de 900 de grame.

Cum se poate afla DINTR-O SINGURA CANTARIRE in care care vagon se afla bilele de 900 de grame ?


PS : DusTeR nu raspunde ca o stii pe asta

Am zis si eu sa postez ceva mai inteligent pe forum, ca sa nu raspunda toti cu un IQ < 90 -

Eu am intrebat cum se face -
Si referitor la raspunsul tau, de ce nu ar putea sa fie si in vagonul 3 bilele de 900 de grame

ma, vagonul poate fi in orice pozitie.
sansele ca un vagon sa fie ala mai usor, e 1 din 10.

insa ce vreau sa intreb eu, cum iti dai seama dintr-o singura cantarire care e mai usor, daca nu stii numarul de bile?

nu ai termen de comparatie, daca-l cantaresti pe ala mai greu, poti spune ca-i ala mai usor, ca nu stii cat au celelalte (bilele au greutate individuala, dar nu stii cate sunt) deci poti sa ai 35436 de bile dar daca nu stii greutatea totala, nu poti compara.

liq : corect -

Este super simplu...im primul rand avem niste cnditii: Trebuie sa fie cel putin 10 Bile

Din prima cutie iei o bila, din a doua doua, si asa mai departe pana la 10..adica din ultima cutie 10bile....le punem toate pe cantar....si calculam greutatea.....observam cate grame ne lipsesc si asa putem spune in care cutie sunt de 900 grame
