because 8/100 women originally said that they married 2x, take 5000/.08 (or 5000/8%)

Unless this is a trick question  . . . :-)
I'd compare the first sample (n = 100) and the second (n = 5,000).
This is a  proportion problem. The second sample is 50 times larger, so the number of women over 35 married two times or more should also be 50 times larger.
Or 50 X 8 = 400
So I'd answer "D."
Hope that helps?
