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.

Answer: B

請問為什麼1)不能solve這問題?
1) 7 represents 12.5% (0.25x0.50=0.125)
所以公司總共有7/0.125=56

不可以這樣算嗎?

題目又沒說 男員工 跟業務員是獨立事件
當然不能這樣算
