I am sorry but you are wrong.
correct answer is E
and the source is a practice material for a coaching institute.

Hope now when you will solve it will definitely post the explanation as well.

however ||X|| double absolute value? what difference between absolute value and double absolute value?
nothing different.... weird.....
i dont understand the answer choice C too....

I don't know what to say on this.
It would be wonderful if experts comment on this.

There's no difference between absolute of x and absolute of absolute of absolute of ... of x.
Allow me to use "[" syntax as an absolute syntax.
x/[[x]]<x
I'll divide this into 2 cases. When x>0 and when x<0

1. When x>0
x/[[x]]<x means
1/[[x]]<1 or [[x]]>1 (divide two sides to a positive number, the inequality sign will not change)
or [x]>1
Thus x>1 or x<-1 However, when this is combined with x>0, the final range of x must be x>1.
2. When x<0
x/[[x]]<x means
1/[[x]]>1 (divide two sides to a negative number, the inequality sign will change) or [[x]]<1
or [x]<1
Thus -1<x<1, however when this is combine with initial condition "x<0", the final range of x: -1<x<0

The final step, combine two range of x of 2 cases:
x>1 and -1<x<0, the result will be x>-1, but excluding the range 0=<x=<1 (Draw all those ranges in value axis for a clearer view, if needed). Now I will try to prove all value in this excluded range acceptable, if I can, the final range will be x>-1
Note at this range 0=<x=<1, there're two integers: 0 and 1.
0 is eliminate as X is differ from 0 ( stated in the hypothesis)
1 remains, and 1 makes the inequation incorrect : 1/[[1]] does not smaller than 1
So the range x>-1 has a value "1" unacceptable. So this range can not be the answer. Let's look at the choices.

The ultimate range must be x>1, however in the answer choice, there's only x>2
The value x = 2 make the inequation correct ( 2/[[2]]<2) so the range x>2 misses a correct value x =2

However, the range x>-1 includes a wrong value x=1
Both are not absolutely correct, but they seem to be the two best possible answers.

Please check the source please.

i dont know what source it is from but for what i have seen from the CR and maths you posted, i think all CR
questions you posted are from CR1000 and mathematical questions are so weird and odd because they are not
clear ( for the answer choices part) and since we seen this problem happening in any source, we should not tend to
put too much effort on the source since it could make our logic worse or make us mad...
heheh (winking at ya)

lolz..........
Brother nothing is intentional. have given a test from my coaching institute portal and this what i got.
I scored only 590 in the test and they claim you should be scoring at least 60 points more they say the level the test is very low.
so what to say that's why i put up all the questions on the forum for discussion.

Hope you understand and help me understand the questions
