Q12:
A certain dealership has a number of cars to be sold by its salespeople.  How many cars are to be sold?
(1)If each of the salespeople sales 4 of the cars, 23 cars will remain unsold.
(2)If each of the salespeople sales 6 of the cars, 5 cars will remain unsold.

这题的答案是C
不过这题我的理解是....条件1&2分开不成立...但为什么合起来OK呢?
我觉得答案应该是E啊....因为还是无法确定到底有几辆车...31,43,55不是都符合吗?
