Question

If Q=open curly brackets x colon x equals fraction numerator 1 over denominator y end fraction comma text  where  end text y element of N close curly brackets comma text end textthen-

  1. 0 element of Q    
  2. 1 element of Q    
  3. 1 element of Q    
  4. fraction numerator 2 over denominator 3 end fraction element of Q    

The correct answer is: 1 element of Q


    To find the correct option according to the given set condition Q.
    From the given options, 1 element of Q implies that
    1 over y = 1
    therefore, y = 1 which is natural number.

    Hence, 1 element of Q is correct.
