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

From B

(80-x)(.42)=Female

2 equations, 2 unknowns.

Is there a flaw in my logic?

(x-14)=Female who have cars!
(80-x)(.42)=Female who does not have cars.

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

Thanks.

St1) Insuf. 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.

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 :D
