1. X is an integer ..Nothing can be said

2.X2 < 1 ..Possible only when X is between 0 -1 or x = 0

In either of the case mod{x-6} is always greater than 5 ..

So Answer is B...correct me if i am wrong

Cheers

although B stands - i would say that the value of x can lie between -1 and 1 ( exclusive of those values)....

Hey

this is B....


|x-6| >5?

1) x is an integer than x=4

|4-6|=2 which is <5

x can be 20

|20-6|= 14 which is > 5

insuff

2)

X^2<1

then X is a fraction

say X is 1/2

|1/2-6| = 5.5 which is >5

or X could be 0

|0-6| = 6 which is > 5...

so either way we can that (2) is always sufficient...it is always >5

B it is...

so x should be b/w -1 and 1.
Then for any such value | x - 5 | > 6

However, i answerd B as the OA, the question is poorly worded. suppose if statement ii is not sufficient to answer the question, statements i and ii jointly cannot answer the question because these statement contradict each other.
