x2 < 1/100
,
and x< 0 What is the tightest range in which x can lie?

-1/10 < x < 0
-1 < x < 0
-1/10 < x < 1/10
-1/10

• since x can have only a negative value...option c is out
  
  now x= -1/10 ...so any number like -1/11 will give x2=1/121 which is smaller than 1/100
  
  as we decrease the denominator we are approaching 0
  
  so the answer has to be option A

• given x2 < 1/100
  so, x < 1/10 or x > - 1/10 - first statement
  also, as per question x < 0 - second statement
  so, intersection of both statement will be
  - 1/10 < x < 0

• (x - a)(x - b) < 0 then value of x lies in between a and b.
  (x - a)(x - b) > 0 then value of x does not lie inbetween a and b. or ( −∞, a) and (b, −∞) if a < b
  x2 < 1/100 ⇒
  (x2−1/100)

• A) x have -ve value then
  check option 1 is suitable for above condition

• option b should be correct..as x= -1/10,in option a..x is greater than -1/10..it cant be equal..so technically b is the right answer
