Réponse :
1) 20% = 0.2
CM = taux + 1 = 1 + 0.2 = 1.2
185*CM = VA = 185 * 1.2 = 222
2) Taux = -15%
CM = 1 - 15% = 0.85
22.95/CM = 22.95/0.85 = 27
3) 1075*1.002 = 1077.15
Taux = 1 - 1.002 = 0.002 = +0.2%
4) 240/180 = CM = 1.33
Taux = -33%
5) VD = 38.01 / 0.21 = 181
Taux = 1 - 0.21 = 0.79
6) CM = 2
VA = 421 * 2 = 842
