1.6.1.41 Diagrama Percentatge Interpretar En una població imaginària, la taxa d'atur presenta l'evolució següent:

En quin any es va produir una disminució de l'atur? l'any {#1}
En quin tant per cent va disminuir l'atur? {#2} El 2008 l'atur era del #n_1 %
Si la població tenia #h habitants l'1 de gener de 2008,i augmenta d'un #a % anual (atenció, és com un interès compost), quants aturats hi ha al final del 2012? {#3}
