Un pepene asezat pe un taler al unei balante este echilibrat cu o greutate de 8 kg. Acelasi pepene asezat pe celalalt taler este echilibrat cu o greutate de 9 kg. Daca doriti sa cumparati 20 de kg dintr-un produs, cantarind 10 kg pe un taler si 10 pe celalalt taler al aceleiasi balante, castigati sau pierdeti ?   Care e diferenta ?
