※ 引述《chilis (chilis)》之铭言：
: 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.
: ---------------------------------------------------------------------
: Answer: C
: 请指教^^
(1)跟(2)单独一定不够
如果两条件并列，设共有x位销售人员
4x+23=6x+5，解x=9
车辆数为59，故两条件并列可以得解
