Percentage

[siddharth11.sharma]

Of all the attendees ata dinner party, 40% were women. If each attendee arrived at the party either alone or with another attendee of the opposite sex, what percentage of the total number of attendees arrived at the party alone?
1) 50% of the male attendees arrived with a woman.
2) 25% of the attendees arriving alone were women.

How can I deduce the asked percentage of alone attendees from second statement?

Sorry for bumping this old thread, but this is a question from one of the MGMAT CATs.
I wanted to understand if this could be answered using the overlapping set double matrix? If so, how would we set it up?
