|x-6| would always be +ve. The "tipping points" would be
x-6 > 5 => x > 11 OR
x - 6 < -5 => x < 1.

1. If x is an integer makes no difference. Insufficient.

2. x < 1. This is the tipping point. For x < 1, x - 6 would always be < -5 and this |x - 6| would be greater than 5.

Thus B.

Quick question, why do you reverse the inequality in the second case?
absolute(x-6)<-5

Is |x-6| > 5

St1:

X is an intger. Useless. x could be 2, then |x-6| < 5 or x could be 1000, then |x-6| > 5

St:2

x < 1

All values of x that satisfies the given inequality will give |x-6| > 5.

Ans B

Clear B.

1) not suff. x = 5 make |x-6| < 5 and x = -1 makes it > 5
2) for every value of x <1, |x-6| > 5

As an alternative approach we may use graphs in certain cases. See post

st1 X IS AN INTEGER
St 2 X <1

Using Option 1 , x < 1 and x > 11 will make |x-6|>5. No unique solution for x.

Using Option 2, x <1 is uniquely makes |x-6|>5
