Statement B is sufficient .

From the table it is clear that # of cars sold each year = #of leases + # of purchases
For 2002 # of car sold -> 100 = V + Z
statement B ->100 = (z+30 ) + Z
hence Z = 35 ( # of cars purchased )

Statement A is Not Sufficient.

Statement A: this tells us that the value of V< 50. This results in multiple values of Z, which makes the statement insufficient.
Statement B: V=Z+30. this gives us one unique solution. sufficient
