In a survey of 248 people, 156 are married, 70 are self-employed, and 25% of those who are married are self-employed. If a person is to be randomly selected from those surveyed, what is the probability that the person selected will be self-employed but not married?

A. 1/8
B. 4/31
C. 117/248
D. 1/4
E. 31/117

A side note to sharmin.karim - you can search on these problems in this forum itself before posting. Also you are not posting OA.

Thanks 2amitprakash. I did a search, but nothing was coming up. What do you mean, not posting OA?

OA - Official Answer.
I assume that you are putting these Qs from GMAT Prep. The official answer will be there and that helps in verifying whether we got it right or not.
