Question

Let R be a reflexive relation on a finite set A having n elements, and let there be m ordered pairs in R. Then,

  1. m greater or equal than n  
  2. m less or equal than n  
  3. m equals n  
  4. None of these  

The correct answer is: m greater or equal than n


    Since R is reflexive relation on A
    therefore left parenthesis a comma a right parenthesis element of R for all a element of A
    rightwards double arrow The minimum number of ordered pairs in R is n
    Hence, m greater or equal than n
