    The greater number among \[\sqrt{17}-\sqrt{12}\] and \[\sqrt{11}-\sqrt{6}\]is_____.

    A)  \[\sqrt{17}-\sqrt{12}\]               

    B)  \[\sqrt{11}-\sqrt{6}\]

    C)  Both are equal

    D)  Can't be compared

    Correct Answer: B

    Solution :

    \[\sqrt{11}-\sqrt{6}=3.3-2.4=0.9\] and \[\sqrt{17}-\sqrt{12}=4.1-3.4=0.7\] So, \[\sqrt{11}-\sqrt{16}\]is greater.
