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
