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

looks to be B.

#of female=(x+16) where x=#of men

(x+16)/x=75/25

solve for x..

(1) doesnt say much..
