Un tren calatoreste de la A la B. Un anumit numar de calatori se urca in tren la plecare. Din acestia, jumatate coboara la prima statie, dar urca alti douazeci. Cand trenul ajunge la a doua statie, jumatate din pasageri coboara, urcand 16. La a treia statie, iara jumatate coboara, urcand 17. Urmeaza destinatia, unde coboara toti calatorii. Aici se constata ca numarul calatorilor de la destinatie este fix jumatate din numarul calatorilor aflati in tren la plecare.

Cu cati calatori a plecat trenul ?
