    A person borrows Rs. 4000 from a co-operative bank at \[7\frac{1}{2}%\]compound interest. At the end of every year he pays Rs. 1500 as part repayment of loan and interest. How much does he still owe to the co-operative bank after three such installments?

    A)  139.20            

    B)  127.60

    C)  144.25            

    D)  123.25

    Correct Answer: D

    Solution :

    Balance \[=\left\{ 4000\times {{\left( 1+\frac{15}{2\times 1000} \right)}^{3}} \right\}\] \[-\left\{ 1500\times {{\left[ 1+\frac{15}{2\times 100} \right]}^{2}}+1500\times \left[ 1+\frac{15}{2\times 100} \right]\times 1500 \right\}\]= Rs. 123.25
