Interesting... we know employed students are 42 and we condisered that as the universal set... But we don't have any information about not employed or not students meaning there could be people who are neither students nor employed in that case the value of universal set will change but the intersection of students and employed would still remain the same I would think... _________________

It is a group of employed, unemployed, students, and those who are not students.

S1:29 are employed, so 13 are unemp. -insuff
S2:24 are st., so 18 are not students -insuff
Together: insuff 'cause there are no info about emp who are students. There could be unemp. who are students and stu. who are unemp.

I tend to disagree... we are given that set A (employed) = 29 and set B (students) = 24 and we are ask to find the intersection (employed students) of both we dont care about A-B at all in this case.

Iali, can you verify the answer. _________________

But we do not have suff details to ans how many. It could be anywhere between 11 and 24.

Say, for eg, all students are empl. Then ans is 24. Worst case scenario, if all unempl. are students then ans is 24-13=11.

So insuff.

But that's what it is clearly said that the number 42 has all the employed students... so I think we have to just think of that but I understand that if that was not the case then it could be a question mark and hence the answer would be E _________________

The Q says "How many of a group of 42 are employed students?"
If it says all 42 are empl. students, then 42 is the ans. Then what are we looking for? Why do we need S1 and S2?

I interpret the question as saying that union of students and employed is 42 now find out the intersection.... _________________

I still think the question is vague.

To be honest, the question itself is simple but the wording is horrible.
