In 1990 all of the people who applied for a job at Evco also applied for a job at Radeco, and Evco and Radeco each offered jobs to half of these applicants. Therefore, every one of these applicants must have been offered a job in 1990.

The argument above is based on which of the following assumption about these job applicants?

(A)all of the applicants were very well qualified for a job at either Evco or
Radeco…
(B)All of the applicants accepted a job at either Evco or Radeco.
(C)None of the applicants was offered a job by both Evco and Radeco.
(D)None of the applicants had applied for jobs at places other than Evco
and Radeco.
(E)None of the applicants had previously worked for either Evco or
Radeco.

the answer is C, could any one tell me why not A, B
thank you

we need to prove that each applicant (whatever be the qualification) got the job. A is out.

Applicants have the choice of only 2 companies, they need to take the job there itself. Not an assumption...it's evident.

C-->consider: If A1 and A2 were to apply for a job in Accenture and Merrill Lynch, and if A1 gets an offer from both, but A1 joins Merrill Lynch, then Accenture is short of one person (or has an open seat). In any case, A2 left stranded, without a job :cry:
But if A1 had received an offer from Merrill Lynch and A2 from Accenture, then both A1 and A2 would have left happily with a job. :-D

was confused at first but goit the idea now....


lets take an ex : there were 100 guys( gals) who appeared for a job at both evco and radco...

conclusion says: all of the applicants mus have been offered = none of them is left out....

now that is only possible when vevry single guy out of the 100 guys was offered a job only at one of the placez...

50 at radco and 50 at eveco....
and all 100 have been given the jobs...

hope that helps DJ' s explanation was perfect...

HAVE fun :)

Thank you DJ,

But I wonder know why is not B?

In fact, what's the difference between B and C?

if no (B), an applicant can accpet both two jobs or no job, the conclusion will not be drawn? right?

I understand that is a bit confusing. Choice B says, all of the applicants got the job, but this can't be proved unless Choice C is False. If there is an overlap (1 applicant got job at both), then B would be wrong.

100 applicants were interviewed...
B: 50 got the job at Avco, 50 at Radeco.
But, if the probability of choosing candidate 2 reaches 200% (selected by both), probability of candidate 2 reaches ZERO. Thus, we can't assure B unless C is correct. And that (read C) would be the base assumption.

Sum up: if we assume C, B would become a fact (not an assumption). C would lead to B.

I hope, I didn't digress from the point :wink:

Read FALSE as TRUE :wink:

I eliminated A and B both because they are out of scope. D and E too.

A is wrong because nothing is mentioned about qualification.
B is wrong because nothing in the argument talks about candidates accepting the jobs.Notice that "accepting" is not even there in the passage.

All the passage talks is about is that each company offered jobs to 1/2 of the candidates.

D and E are again out of scope.
D. The passage doesnt talk about candidates applying elsewhere
E. Nothing is mentioned about candidates having worked previously in the companies.

Does anyone agree with me ?
