    I.\[x=\sqrt{784}\]                   
    II.\[{{y}^{2}}=784\]             

    A)  if\[x>y\]                      

    B)  if\[x\ge y\]        

    C)         if\[x<y\]          

    D)         if\[x\le y\]

    E)  if \[x=y\] or relationship between \[x\] and \[y\] can't be established.

    Correct Answer: B

    Solution :

    I.\[x=\sqrt{784}\] \[\therefore \]\[x=28\] II.\[{{y}^{2}}=784\] \[\therefore \]\[y=\pm 28\] Hence\[x\ge y\]
