    A sum of money amounts to Rs. 1352 in 2 yr at 4% per annum of compound interest. The sum is    

    A) Rs. 1200

    B)  Rs. 1250

    C)  Rs. 1280

    D)  Rs. 1296

    Correct Answer: B

    Solution :

    If the principal be Rs. x, then A = P \[{{\left( 1+\frac{R}{100} \right)}^{T}}\]
    \[\Rightarrow \]   \[1352=x{{\left( 1+\frac{4}{100} \right)}^{2}}\]
    \[\Rightarrow \]   \[1352=x{{\left( \frac{26}{25} \right)}^{2}}\]
    \[\Rightarrow \]   \[x=\frac{1352\times 25\times 25}{26\times 26}\]= Rs. 1250
