有两题数学DS不只怎么解,
When 115n,where n is a positive integer,is divided by 6,the remainder is x.what is the value of
1.When n is divided by 2,the remainder is 0
2.When n is divided by 3,the remainder is 0
The answer is A.how can i know that a is sufficient?怎么了列式子分子呢?
What is the median number of employees assigned per project for the projects at Company
1.25 percent of the projects at Company Z have 4 or more employees assigned to each project.
2.35 percent of the projects at Company Z have 4 or few employees assigned to each project.

首先15n/6=5n/2
1.当n被2整除时,5n/2的余数一定是0,所以1是充分的.
2.当n被3整除时,5n/3的余数是不定的,所以2是不充分的.
1是充分的,2是不充分的.
1.当n被2整除时,5n/2的余数一定是0,所以1是充分的.
