For real numbers x and y define a relation R, `xRy iff |x|=|y|`, the relation R is

For real numbers x and y define a relation RxRy hArr|x|=|y|, the relation R is

In a set of real numbers a relation R is defined as xRy such that |x|+|y|<=1 then relation R is reflexive and symmetric but not transitive symmetric but not transitive and reflexive transitive but not symmetric and reflexive (4) none of reflexive,symmetric and transitive

For real numbers x and y, define xRY if and only if x - y + sqrt(2) is an irrational number. Then the relation R is

For real numbers x and y define x\ R\ y if x - y + sqrt(2) is an irrational number. Then the relation R is

For real numbers x andy, define x R y if x - y + sqrt(2) is an irrational number. Then the relation R is

For real numbers x and y , define x\ R\ y iff x-y+sqrt(2) is an irrational number. Then the relation R is (a) reflexive (b) symmetric (c) transitive (d) none of these
