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.
1) let's say 100 people in the company: 25 males and 75 females, and 50 sales staff and 50 non-sales staff. we can have 7 males and 43 females who are sales staff. if there were 200 people in the company, 50 males, 150 females, 100 sales staff and 100 non-sales staff, we can still have 7 males and 93 females who are sales staff. Insufficient.
2) If there are x number of people in the company, 0.75x-0.25x=16. x=32. Sufficient
