I am totally confused as to why the answer isn't D. Seems to me like statements are saying the same thing. I used actual numbers and my answers proved that both statements were sufficient: Statement 1: pqp=p So if p=2, then 4p=2 and p=1/2 so p*q does equal one (2*1/2)=1, correct? Statement 2: qpq=q ...

The answer should be E First off, neither statements are sufficent alone b/c each provides info about one of the variables. Putting the statments together--pick multiples of 8 for n and 4 for k: n=8, 16, 24, 32, 40, 48 etc. k=4, 8, 12, 16, 20, 24, 28, etc. So, put the statements together: -If n=8 an...

YES--its definitely worth it, especially if you don't know your strengths and weaknesses are in GMAT quant. The quiz gives ou 24 questions to solve in abourt 42 min (I think). Once you finish, you get a score range and then the system breaks down each question type (DS and PS) and the question mater...

In statement 1, it states that k@1 does NOT equal 1@k, so that rules out addition and multiplication and is only true for addition. In addition and multiplication operations, you can arrange the integers in an equationand still get the same answer. Only in division and subtration, this does not hold...

Start with the easier statement, (2)--> 0>x INSUFFICIENT Statement 1 states that the absolute value of z is greater than the absolute value of y, but it doesn't tell us about the value of x-->INSUFFICIENT. Put the two statements together: so if 0>x, pick a negative number for x and if the abolute va...

Sure, let me help: First, simplify the given equation--square both sides of the equation to change your statement to: Is (x-5)^2=(5-x)^2? Start off with statement 2 since its the easier one: 5-x>0 so x can EITHER be positive or negative for this to be true. Plug in -1 as an example. 5-(-1)=6. Plug i...

I got C as an answer too--Volume of a cube is s^3 since all sides are equal. Therefore, all the sides=4. The longest length in a quadrilateral is the DIAGONAL, and a diagonal in a cube splits a sides into 2 isoceles triangles. Draw a diagram of a cube with the diagonal splitting the front into a tri...

Oh, sorry, my bad, I was writing out too many of the equations at once. Here's a clearer approach: Statements 1 and 2 ALONE are both insufficient b/c they are missing a variable (statement 1 is missing X and statement 2 is missing Y) Line all the equations up and convert 2 of them: X+Y=3-->X=3-Y Y+Z...

I'm sure I'm doing this the long way, but here it goes: Statment 1 is insufficient b/c the equation does not give you a value for x. Statement 2 is insufficient for the same reason--you are not given a value for y. Statements 1 and 2 together--write out equations and subsitute values: x+y=5-->x=5-z ...
