### HideShow timer Statistics

The proportion of women among students enrolled in higher education programs has increased over the past decades. This is partly shown by the fact that in 1959, only 11 percent of the women between twenty and twenty-one were enrolled in college, while in 1981, 30 percent of the women between twenty and twenty-one were enrolled in college.
To evaluate the argument above, it would be most useful to compare 1959 and 1981 with regard to which of the following characteristics?
(A) The percentage of women between twenty and twenty-one who were not enrolled in college
(B) The percentage of women between twenty and twenty-five who graduated from college
(C) The percentage of women who, after attending college, entered highly paid professions
(D) The percentage of men between twenty and twenty-one who were enrolled in college
(E) The percentage of men who graduated from high school

I could not understand the reasoning behind the answer.

I could not understand the reasoning behind the answer.

this is interesting.. does this mean that in 1959, of 100 students, there were 11 women in college
whereas in 1980, of 100 students, there were 30 women in college..
to make sure that this is correct, we need % of men between 20 and 21.. which according, to above example should be 89% in 1959 and 70% in 1980...
So D.
------------------------

but my confusion is- This is partly shown by the fact that in 1959, only 11 percent of the women between twenty and twenty-one were enrolled in college, while in 1981, 30 percent of the women between twenty and twenty-one were enrolled in college.
does this mean that of women population in the city or locality, 11% were enrolled, OR
does this mean in the college, of all enrolled students, 11% were women.

I could not understand the reasoning behind the answer.

1959:
Total number of students enrolled=100
Women (20-21): 11
Men: 0
Obviously then, Women NOT(20-21): 89

Thus, proportion of women enrolled in 1959=100%

1981:
Total number of students enrolled=100
Women (20-21): 30
Men: 70
Obviously then, Women NOT(20-21): 0
Thus, proportion of women enrolled in 1981=30%

Thus, the proportion of woman in total students decreased from 1959 to 1981.

1959:
Total number of students enrolled=100
Women (20-21): 11
Men: 89
Obviously then, Women NOT(20-21): 0

Thus, proportion of women enrolled in 1959=11%

1981:
Total number of students enrolled=100
Women (20-21): 30
Men: 0
Obviously then, Women NOT(20-21): 70
Thus, proportion of women enrolled in 1981=100%

Thus, the proportion of woman in total students increased from 1959 to 1981.

Conclusion:
If we know what percent of men were enrolled in 1959 and 1981, we can exactly find the proportion of women among the students enrolled.

Ans: "D"

In simple words, in order to support that the percentage of women increased, one needs to know the class composition which has a direct impact on the increase or decrease of the women %age in class.

The stem talks about "The proportion of women among students....". We can infer that class is composed of both men and women & not only of women of various age groups.

What if we had another answer choice as follows:

(F) The percentage of women between twenty and twenty-five who were enrolled in college

This definitely would have added some confusion (to choose between D & F) and in that case the information that class is composed of both men and women (inferred from stem) would have been helpful.

Although I agree that D is the best choice here. But I don't agree with the explanation that of total 100 students enrolled in the class, 11 women enrolled and 0 men enrolled. Who are these rest of the 89 people enrolled in the class? kids? animals?

It's neither animals nor aliens. It's the number of women who are not between 20 and 21. You got to learn how to interpret a solution before criticizing it. See the text in red above.

I know man. I suck at it and need to learn. Since you insisted, I went over the explanation again, and I agree your illustration has no problem at all--I missed the NOT part. Must have been the long day the other day. I hope you are not considering me for your foe list

Looks like a DS question to me......Too lazy to solve....so went with A first thinking that
(Even though, my hunch was D initially - come on - Will the question assume that class has only Men and Women ? So Men % will be sufficient )
Yes-D is correct ,logically as well :D

(A) The percentage of women between twenty and twenty-one who were not enrolled in college
Does it matter even- nonetheless a lucrative answer
(B) The percentage of women between twenty and twenty-five who graduated from college
We are not bothered about this group, if at all we would be interested in other than 20-21 enrolled group
(C) The percentage of women who, after attending college, entered highly paid professions
An out of scope answer
(D) The percentage of men between twenty and twenty-one who were enrolled in college
Sounds ok, lets keep it for now
(E) The percentage of men who graduated from high school
We are looking out for enrollment not graduated %ages- are not we

I could not understand the reasoning behind the answer.

Initially I was looking for something like other than 20-21 year woman %ages (or total women enrolled %ages) but then could not find so by elimination we have D (fills the position for the rest of the group)

oops, Remember, premise says 11% of overall women (20-21 yrs) were enrolled, so the remaining 89% of the 20-21 yrs women were not enrolled(it is not about men, not even 100 students exist college)

-option D would be right if the premise would say '11% of enrolled students were women (20-21 yrs)'
but there is no option to determine the proportion of women (20-21) to men (20-21)

this question has nothing to do with calculations or anything of that sort.
If there are a particular number of students in a class(obviously only 2 groups- boys and girls) , then the number of girls in the class depends on the
number of boys, and vice versa. Now since we are concerned with only one age group (20-21) , Option D is the clear winner.

Time taken should be around 30-40 sec.

read the premise again, 11% of the (women btn 20-21 yrs) were enrolled in college, so remaining 89% of the (women btn 20-21 yrs) weren't enrolled

what we are evaluating is whether the proportion of women among students enrolled has increased over the past decades. To know that proportion, we need the number of men among students enrolled and the number of women among students enrolled.

the number of women among students enrolled is given by the premises. So we are only missing the number of men among students enrolled, which is given by option D.

to answer this question correctly we must have information on percentage of men between twenty and twenty-one enrolled in college in the two period of 1959 and 1981.if the percentage of men dropped then surely the percentage enrollment of females is going to increase
So correct answer D
