At a certain company, 25 percent of the employees are male and 50 percent of the employees are sales staff.What is the number of employees at this company?

(1)Exactly 7 of the employees at the company are males who are sales staff.

(2)There are 16 more female employees than male employees at the company.

我明白2肯定对，但是1我想了很久，可不可以解释一下为什么不对？
答案就是B！
