I think the answer to this problem is A. Solving the first equation we get that x=1 or x=-1 in any case the absolute value of X will be 1 which is greater than 1
Second clue doesnt actually help as xNE 3 as in X can take any value.
Just try checking this answer with others I might not be correct though I feel this might be correct.

roopachet's explanation, as usual, makes no sense and is completely incorrect.
1.) Tells you X = 3 OR 1/3. Insufficient.
2.) Tells you X NE 3. Insufficient.
Together, X = 1/3. Sufficient.
Answer is C. |

beny, I have following some other posts of yours too and it seems like you are taking this personally. You need to calm down and stop making personal remarks. Remember that just because a problem/solution/concept is easy for you DOES NOT mean that its easy for everybody else.

i agree .. beny u need to stop targeting a a particular forum user .. dont get me wrong over here .. it is great to see u helping out the members over here .. but u need to understand that there is always going to be someone on the forum who is better than u and also someone who is not as good as u in solving quant .. remember the point behind the whole forum is to learn from each others experience .. So plz stop making personal remarks .. |
