    A) Rs. 390             

    B) Rs. 395

    D) Rs. 405

    Correct Answer: C

    Solution :

    Given that \[A=Rs.\,441,\] \[r=5%\] and \[n=2\,yr\] \[\therefore \]      \[441=P\left[ {{\left( 1+\frac{5}{100} \right)}^{2}} \right]\] \[\Rightarrow \]   \[441=P\left( \frac{441}{400} \right)\] \[\Rightarrow \]   \[P=\frac{441\times 400}{441}=Rs.400\]
