1. The distance between s and 0 is the same as the distance between t and 0.
2. 0 is between s and t.
OA: a

s+t=0, this can only be possible if s and t have the same absolute value but different signs.
therefore, we are just trying to find if lsl = ltl ?
Statement I
ls-0l = lt-0l
lsl = ltl
Sufficient.
Statement II
We dont know if s and t have the same absolute value, we just know that one is negative and one is positive.
Hence A.
Hope this helps.
I think that would be an assumption.nandansingh wrote: One doubt...
Statement-2: Zero is between s and t.
Does that not mean that 0 is right in-between and hence the midpoint between s and t. hence s and t have same absolute value but opposite sign. hence s+t=0!
you're right!!...krazy800 wrote:s and t should be different numbers as given in the problem.......
. I really need to stop doing silly mistakes like this...
