In a group of 80 college students, how many own a car? (1) Of the students who own a car, 14 are male (2) Of the students who do not own a car, 42% are female

Getting C. x=own a car from A (x-14)=Female From B (80-x)(.42)=Female 2 equations, 2 unknowns. Is there a flaw in my logic?

I was expecting someone to correct my logic, something was missing in the question (based on my intuition), but formula SEEMED to work. Thanks.

80 students---- A) of the students...14 male... no info on female.... INsuff B) Same reasoning !! Insuff C)Nothing IMO E vishu

Hint: [spoiler]it's not E[/spoiler] Another hint?

We need to know females who own a car. St2) 42% female, 58%male 42+58=100 but we have only 80 students. if we keep the same ratio: 21 female / 29 male ( here is the magic in this question, 29 is a prime number so ) 21 female and 29 males do not have any car = 50 people so 80-50 = 30 people have car - SUF Choose B, great question.

Brent, If the question is complete as is then pl dont give any hints. This way we know what we missed.

Exactly - we can't find 42% of many numbers and get a whole number (i.e., a whole person). Given the 42% part, this means that there must be 50 people without a car, and thus 30 people with a car. Awesome! Great work, Logitech. I think you're ready to take the GMAT
