Questions!! [#permalink] New post 26 Jul 2011, 09:22
Hey guys!
Please help me out. I just began studying for the gmat a week ago. I have a few questions. These are from the GMATprep test.

D/S question
1. Are atleast 10% of the people in country X who are 65 or older employed?

1) In Country X, 11.3% of the population is 65 or older.
2) In County X, of the people 65 or older, 20% men and 10% women are employed.


2. For which of the following function is f(a+b) = f(a) + f(b) for all positive numbers a and b?
(This question sort of seems weird to me, I dont even exactly understand what its asking)

a. f(x) = x^2
b. f(x) = x+1
c. f(x) = (x)^1/2
d. f(x) = 2/x
e. f(x) = -3x

3. What is remainder when positive integer x is divided by 3?
1. When x is divided by 6, the remainder is 2.
2. When x is divided by 15, the remainder is 2.

4. What is x (See attached pic)
1. QR=RS
2. ST=TU

5. What is the ratio of KN/MN? (see rectangle pic attached)
1. Perimeter of KLMN is 30.
2. Three small rectangles have the same dimensions.

Please provide explanations. Help me out! Thanks! :)

In question no. 5th, Statement II is enough to answer.
is All 3 small rectangle have same dimension, thus
KN/MN= x/(3/2x) = 2/3

4. Both equations together are sufficient, but neither equations alone are sufficient

If you take the total triangle, you know the bottom left is 90, and then you have the two other angles you need to find x, so if we call both these angles a and b then 90+a+b=180. When putting them together it is sufficient but neither alone can be solved.

I'm sorry if this makes no sense at all as I am restless and awake in the middle of the night.
