How come A isn't sufficient.
if b = (a/100)^-1 then b = (100/a)
So ab = (a/100)(100/a) = 1
Then 1 X c (which is an integer) = c (an integer)
What am I doing wrong?

MGMAT - The Power of Percents
If a, b, and c are positive integers such that a < b < c, is a% of b% of c an integer?
(1)b = (a/100)^-1
(2) c = 100^b

Veritas Statistics/Probability/Combinations Book
I took the GMAT this Saturday. I scored a 680 (Q44/V40). I feel pretty confident in my verbal, but obviously math is where I need to improve. I already did all of the quant questions in the OG Official Guide, OG Verbal Guide, and the Kaplan800 book. I'm going on a trip so I'll start studying again i...

Just took the GMAT today. Scored a 680. I'm likely going to retake, but I'm a realist so I know I could score the same or lower.

Thanks Rich, I was definitely confused because I was trying to use x
x√2 and I couldn't understand how it could work so I panicked!

In the question, the perimeter is 16 + 16√2, so we can create the following equation: x + x + x√2 = 16 + 16√2, Simplify: 2x + x√2 = 16 + 16√2 IMPORTANT: Factor x√2 from the left side to get : x√2 (√2 + 1) = 16 + 16√2 Now factor 16 from the right side to get: x√2 (√2 + 1) = 16(...

Is it generally safe to assume that on the GMAT, if they give us only one point, don't tell us any part of where it intersects and ask what the slope is, it's going to be something like this?
I just couldn't figure out how to find a slope, without assuming one of the three that sukriti mentioned.

I'm sure I am over-thinking this, but technically couldn't a rectangle be divided equally into two trapezoids? Example: A rectangle has a width of 4 feet and a length of 7 feet. You could take 1 foot from the bottom left corner and draw a diagonal through the 1 foot mark on the top right corner. The...
