Word problem?

by eracnos » Tue Nov 11, 2008 11:40 am
Hi guyz

Question:

Of the job applications received by a company, 1/5 are from applicants with fewer than two years of job experience, and 2/5 are from applicants with at least five years of job experience. If the company will accept all applicants with at least two years of job experience, what fraction of the accepted applicants had fewer than five years of job experience?

A. 1/5
B. 2/5
C. 1/2
D 3/5
E 2/3

My answer is C (1/2).
< 2 years is 1/5
> 2 years, but < 5 years is 2/5
> 5 years is 2/5
So 2/5 + 2/5 = 4/5
and 2/5 : 4/5 = 1/2 = C??

My teacher gave me wrong for this question. The correct answer is
D
What is wrong with my logic (I am international so maybe it's an English problem?)

we are dealing with the numbers like 1/5 2/5...
first hint is probably to choose the number which is multiple of 5
assumne num of app =100

1/5=20 < 2

so remaing 80 >2

2/5=40

80 is app is accepted

and in the applicants <5 is 40
40/80=1/2

here i get the same as u !!

I dont see anything wrong here(acc to me atleast)

neone to correct/comments??

I agree with 1/2. I must be missing some trick in the wording if the answer is indeed 3/5.


Eracnos,
Whats the source?

I also feel that C (1/2) is the correct answer, but I went with picking numbers:

1/5 - X < 2
2/5 - X > (or equal) 5; therefore
2/5 2 < (or equal) x < 5

since the fractions are 1/5, 2/5, and 2/5, to make things easy, I selected 125 as the number of applicants (5 x 5 x 5); therefore

1/5 = 25
2/5 = 50
2/5 = 50

100 applicants were accepted, 50 of these applicants had less than 5 years work experience 50/100 = 1/2 = C

Unfortunately I haven't solved the original mystery as to why C is incorrect, but I figured posting picking numbers as an alt. method would be useful.

We betrayed you man! We suck.

Meanwhile please make sure that you did not do anything wrong with copy pasting the question. All of these people are putting their time and effort to help you and we expect you to post proper questions. I am hoping that I am wrong about a typo in your question.

If the company will accept all applicants with at least two years of job experience, what fraction of the accepted applicants had fewer than five years of job experience?

A. 1/5
B. 2/5
C. 1/2
D 3/5
E 2/3

My answer is C (1/2).
< 2 years is 1/5
> 2 years, but < 5 years is 2/5
> 5 years is 2/5
So 2/5 + 2/5 = 4/5
and 2/5 : 4/5 = 1/2 = C??

My teacher gave me wrong for this question. The correct answer is
D
What is wrong with my logic (I am international so maybe it's an English
problem?)
2/5 of applicants have at least 5 yrs exp.
Therefore, people with less than 5 years exp = 1-(2/5) = 3/5. The other info in the question is not needed.

Not all 3/5 are accepted.
