 Acest exercitiu a fost creat de un profesor de matematica de la Universitatea din Barcelona care apoi a cerut elevilor sai sa o rezolve.

Problema: Mama are cu 21 ani mai mult decit copilul sau si peste 6 ani copilul va fi de 5 ori mai tinar decit mama. Intrebare: UNDE ESTE TATAL?

(Note: 1. Gindeste-te bine, cu calm si nu citi imediat solutia!! 2. Aceasta problema se poate rezolva matematic)
