Wow seriously good :) The only way I can think of is actually getting your hands dirty and doing it. (You will only need fast calculation skills :P) Let's say f(x) = x! + (x+1) f(2) = 2! + (2+1) = 5 f(3) = 3! + (3+1) = 10; at this stage we know that if x is odd, we know that f(x) does not output a p...

Are you sure this is a valid question? I can see no way of drawing a linear function with these requirements. (This also does not fit in the "Data Sufficiency" type of questions) The first condition states that f is an increasing function in the {1,2} range (thus the function will look li...

I always remind myself that "GMAT is trying to trick me". I don't like to get tricked, so I try not to let GMAT trick me.
That is how i reason with gmat questions

Is x negative? (1) 2x > x^2 (2) x < 1 [spoiler]OA: A. I have a doubt in how we arrive at the answer from statement 1. Simplifying we get, x^2 - 2x <0 x(x-2)<0 x<0 x-2<0 x<0 x<2. What am I doing wrong here?[/spoiler] Hey man! From your rearrangement: x^2 - 2x <0 x(x-2)<0 ; this statement is correct ...

It says "every" but it does not say "how many". I was given this great advice: "do not assume anything in gmat questions"

The easiest way to solve this is by drawing: Imagine the row starts from left with a male. You will have 4 people to choose from. Next a female. You have 4 people (4 females) to choose from. Next will be a male, 3 options (since you already chose 1). And female with 3 options etc.. So it will look l...

Hey man, I agree with you.. "From" sounds more natural to me as well. However, after reducing the choices to B and D, let's check it out. B is the correct one as the OA says. D is not correct because it is missing some parts. The correct form would have been: "at the busiest times, ha...

The answer should in fact be A :) When you are listing some stuff and separating them with commas you have to make sure that those stuff are of the same type. B)change is from : to ;. The : is perfectly fine. So B is eliminated. C)"force and acc. were related" is wrong here. It should be &...

Hey dude! I believe the question is missing a vital part : The function f is defined for all postive integers n by the following rule: f(n) is the number of positive integers each of which is less than n and has no positive factor in common with n other than 1 . If p is any prime number, then f(p) =...
