Re: GMAT Problem Discussion - 21-12-2006, 08:49 AM

What is the number of female employees in Company
X ?
(1) If Company
X were to hire 14 more people and all of these people were females, the ratio of the number of male employees to the number of female employees would then be 16 to 9.
(2) Company
X has 105 more male employees than female employees.


A Statement (1) ALONE is sufficient, but statement (2) alone is not sufficient.
B Statement (2) ALONE is sufficient, but statement (1) alone is not sufficient.
C BOTH statements TOGETHER are sufficient, but NEITHER statement ALONE is sufficient.
D EACH Statement ALONE is sufficient.
E Statements (1) and (2) TOGETHER are NOT sufficient.

Answers....

Option E) Cannot be answered using both.

Analysis!!:
A----------B---------C----------D
Is
CD > BC ?
(1)
AD = 20
(2)
AB = CD

Here goes..
1) If AD = 20, we can conclude nothing except for its total length.
2) AB = CD, using this we can form an equation:
AB + BC + CD = Total Length
Let AB = CD = x
2x + BC = Total lenght

Cant conclude anythign.

Using Both!!
2x + BC = 20
BC = 20 - 2x

Put x =5; bc = 10; CD < BC
Put x = 7; bc = 6 BC < CD

Thus enough info is not available.
Thus option E.

Hi

You can post all the questions in a single post rather than using multiple posts. And please wait for the junta to solve it. What's the point in giving out the questions and solutions at the same time. You could, say, post five questions...provide a deadline...and then give out teh solutions
