    B)         500

    C)  300                       

    D)         100

    Correct Answer: B

    Solution :

     Given, \[{{6}^{x}}\] \[{{6}^{x}}={{(2\times 3)}^{x}}={{2}^{x}}\times {{3}^{x}}\]            a = 2 and d = 2                 \[\Rightarrow \] \[{{6}^{x}}\]       \[\therefore \] \[{{6}^{x}}\]       \[{{x}^{3}}\] \['x'\]    \[\text{(25}\times \text{7)cm}\]
