A) Reflexive and symmetric
B) Symmetric only
C) Transitive only
D) Anti symmetric only
Correct Answer: A
Solution :
Now, aRa is \[|a-a|=0\le 1,\] which is true. \[\therefore \] It is reflexive Now, aRb, \[|a-b|\le 1\,\,\,\,\Rightarrow \,\,\,|b-a|\le 1\] \[\Rightarrow \] \[aRb\] \[\Rightarrow \]\[bRa\] \[\therefore \] It is symmetric.You need to login to perform this action.
