I use number line for Inequality problems as i find it more acurate x  6>5 or x  65>0 expression is 0 for 1 and 11 divides number line in 3 segments x<1, 1<x<6, x>11 now expression is positive for x>11 and x<1 while for 1<x<11 is negative.
(1) x is an integer not sufficient (2) x^2< 1 or 1<x<1 which is sufficient since expression is positive for all values for x<1

Why are the questions containing $ symbols and many other Questions have terms like "Frac" etc. Its very difficult to understand the Question itself. May I know if the real GMAT test will also have them?

(2) x2<1. So, −1<x<1, as all xes from this range are in the range x<1, hence inequality x−6>5 holds true. Sufficient.
I dont understand this statement. Because 1<x<1 means X=0 Or x=.25 and any other valu. But question inference say that x<1 or X>11. So 1<x<1 how x satisfy x>11. I am not clear about this. Would any one like to help me.

I think this is a highquality question and the explanation isn't clear enough, please elaborate. (2) x2<1. So, −1<x<1, as all xes from this range are in the range x<1, hence inequality x−6>5 holds true. Sufficient.

Let's work on the stem first. For which values of \(x\) inequality \(x  6 > 5\) is true? If \(x \lt 6\), then \(x+6 \gt 5\) or \(x \lt 1\). If \(x \geq 6\), then \(x6 \gt 5\) or \(x \gt 11\). So we have that inequality \(x  6 \gt 5\) holds true for \(x \lt 1\) and \(x \gt 11\). (1) \(x\) is an integer. Clearly not sufficient. \(x\) can be 12 and the inequality holds true as we concluded OR \(x\) can be 5 and inequality doesn't hold true. (2) \(x^2 \lt 1\). So, \(1 \lt x \lt 1\), as all \(x\)es from this range are in the range \(x \lt 1\), hence inequality \(x  6 \gt 5\) holds true. Sufficient.
Answer: B I can`t understand why the option C is not the right answer. According to S2, x can only be anything within 0.99 to 0.99 as 1<x<1. While we take S1, we can say that there is only one integer which is O. Therefore, we can find a certain value for x. Please correct me if i am wrong. Thanks in advance.

Hi Bunuel, If the original stmt is x<1 and x>11
In Stmt II I think that the range 1<x<1 satisfies only one of the two conditions. In this case x<1. what about x>11? Are you implying that x<1<11? Kindly explain.

Is \(x  6 \gt 5\) ?
(1) \(x\) is an integer
Put x =100 ....Answer is yes
Put x =1.........Answer is No
Insufficient
(2) \(x^2 \lt 1\)
1 < x <1 Put x=0.99...........5.01> 5..Answer is yes
Put x=0................6>5.......Answer is Yes
Any negative number will yield yes
Sufficient
Answer: B
