Q:
A certain dealerhsip has a number of cars to be sold by its salespeople.How many cars are to be sold?
(1) if each of the sales people sales 4 of the cars, 23 cars will remain unsold.
(2) if each of the sales people sales 6 of the cars, 5 cars will remain unsold.
答案是C。但是个人觉得应该是E。
(1)T=4A+23 即:27,31,35,39,43,47,51,55,59,63.....
(2)T=6B+5 即:11,17,23,29,35,41,47,53,59,65....
可见(1)(2)综合T并不唯一(如列举47,59)
请教上述思路是否正确? |
