Hi,

It seems I have got a Problem here. what If X equals -3 ( Condition in D is satisfied since X is not 3 it is -3 ; I am fine if the variable in the condition is Mod X instead of X).

Can Someone Pls clarify?


\frac{|x|}{|3|}>1 you can see it as |x|>3 or x>3, x<-3

If x=-3
\frac{|-3|}{|3|}>1 and this is 1>1 which is false.

x cannot be -3, it's inside the range of values (-3\leq{}x\leq{}3) that x cannot assume

Hope it's clear now. Let me know

Hi,

Thanks for the quick response.

I got that can not be -3, I just proposed that as a contradiction to the OA which is D here. Option D says It must be true that X does not equal 3. while It is correct, IMO It is not the only restriction we have here. X can not equal -3 as well ( Just as you explained :) ). so IMO Correct answer should reflect |x| > 3. Here None of the options reflect that condition. Am I missing something very basic here? :)

It's simple: from the quesion we know that x cannot assume values -3\leq{}x\leq{3}

Of course D is not the only possible answer.
You said "Here None of the options reflect that condition", but here we are not asked to find the range of possible values!
We have to check if the values A,B,... fit with the condition above.

Also x≠2 or ≠1 must be true for example, but we have to answer by looking at the possible answer.

So which must be true?
A. x > 3
B. x < 3
C. x = 3
D. x ≠ 3 <---This one is correct
E. x < -3

Hope it's clear now
