    The ratio of areas of two squares, one having double its diagonal than the other is

    A) 2 : 1                            

    B) 3 : 1

    C) 3 : 2                            

    D) 4 : 1

    Correct Answer: D

    Solution :

        Let the diagonals of two squares be 2d and d, respectively. Then the required ratio\[=\frac{{{\left( \frac{2d}{\sqrt{2}} \right)}^{2}}}{{{\left( \frac{d}{\sqrt{2}} \right)}^{2}}}=\frac{4}{1}.\]
