30 employees received promotion.    15 males received promotion.
So 15 females received promotion.    Of the 30 women,  so 15 women did not receive promotion.

number of promoted employees age > 30 yrs :    7 males.
totally  12 males are above 30 yrs
  so  unpromoted males above  30 yrs = 5.      ---- (1)

number of employees with age > 30 yrs  is  = 24
number of promoted employees > 30 yrs is  = 19
number of unpromoted employees > 30 yrs is = 24 - 19 = 5  ---(2)

from (1) and (2)
 number of unpromoted women above 30 yrs age:  5 - 5 = 0
