Probabil ai vrut sa spui ca A = \( \frac{1}{3} \) din V , S = \( \frac{2}{3} \) din V. A + S + V = 48

A =?
B=?
C=?

Pun si eu o problema, mai mult de logica...
Intr-o camera avem un bec, iar in exteriorul camerei avem 3 intrerupatoare. Stiind ca aveti voie sa intrati doar o singura data in camera, cum puteti afla care intrerupator, din cele 3, functioneaza? :D

Apasam un intrerupator si il lasam putin aprins , apoi apasam alt intrerupator si intram in camera . Daca becul este aprins inseamna ca am gasit intrerupatorul , iar daca este stins il atingem sa vedem daca e cald . Daca e cald inseamna ca ii corespunde primului intrerupator , iar daca nu inseamna ca ii corespunde ultimului intrerupator neatins .
