    Which one of the following is true?

    A) \[{{\left( 1+\frac{1}{n} \right)}^{n}}<{{n}^{2}},n\] is a positive integer

    B) \[{{\left( 1+\frac{1}{n} \right)}^{n}}<2,n\] is a positive integer

    C) \[{{\left( 1+\frac{1}{n} \right)}^{n}}<{{n}^{3}},n\] is a positive integer

    D) \[{{\left( 1+\frac{1}{n} \right)}^{n}}>2,n\] is a positive integer

    Correct Answer: D

    Solution :

    [d] Put \[n=1,{{\left( 1+\frac{1}{1} \right)}^{1}}=2\] \[\therefore {{\left( 1+\frac{1}{n} \right)}^{n}}>2,\] n is a positive integer.
