    Which one among \[\sqrt{10}+\sqrt{4},\,\,\sqrt{11}+\sqrt{3},\,\,\sqrt{7}+\sqrt{7}\] is the smallest number?

    A)  \[\sqrt{10}+\sqrt{4}\]   

    B)  \[\sqrt{11}+\sqrt{3}\]

    C)  \[\sqrt{7}+\sqrt{7}\]     

    D)  All are equal

    Correct Answer: B

    Solution :

    [b] Here, \[\sqrt{10}+\sqrt{4}=3.16+2=5.16\] \[\sqrt{11}+\sqrt{3}=3.31+1.73=5.04\] \[\sqrt{7}+\sqrt{7}=2.64+2.64=5.28\] \[So,\,\sqrt{11}+\sqrt{3}\]is the smallest number.
