    B)  Rs. 973.4

    C)  Rs. 979.2

    D)  Rs. 975.9

    E)  Rs. 61

    Correct Answer: C

    Solution :

         \[CI=P\left[ {{\left( 1+\frac{R}{100} \right)}^{T}}-1 \right]\] \[=12000\left[ {{\left( 1+\frac{4}{100} \right)}^{2}}-1 \right]\] \[=12000\left[ {{\left( \frac{26}{25} \right)}^{2}}-1 \right]\] \[=12000\left( \frac{676}{625}-1 \right)\] \[=\frac{12000\times 51}{625}=Rs.979.2\]
