ans is d)

There are 12 married females who are above 25.- 1
using,
[19 are above 25 years, of which 7 are males]

and

from [ 24 software engineers are above 25 years of age] & [ 12 males are above 25 years]

we can say that there are 24-12 =12 females who are above 25 yrs

Now all of these 12 females should have also got married [From 1]

By the way , This has already been discussed about in the QQAD thread .

Cheers!

(A) 12 (B) 8 (C) 7 (D) 0 (E) 11

The answer is (D) 0 females.
If you observe closely, you'll see that all the females above 25 years (which comes to 12) are married. So no unmarried female will be remaining.
