      The amount and compound interest on Rs. 5000 compounded annually for 2 yr 6 months at the rate of 10% per annum is                   

    A)  Rs. 6252.5 and Rs. 1342.5                

    B)  Rs. 6000 and Rs. 1300                    

    C)  Rs.6250 and Rs. 1340                   

    D)  Rs.6352.5 and Rs.1352.5

    Correct Answer: D

    Solution :

    P = Rs. 5000 T = 2 yr R = 10% per annum
    \[A=P{{\left( 1+\frac{R}{100} \right)}^{n}}\]
    \[A=5000{{\left( 1+\frac{10}{100} \right)}^{2}}=5000{{\left( \frac{110}{100} \right)}^{2}}\]
    \[=5000\times \frac{110}{100}\times \frac{110}{100}=\]Rs. 6050
    For 6 months, \[A=6050+\frac{6050\times 10\times 6}{100\times 12}\]
    = 6050 + 302.50 = Rs. 6352.50
    \[\therefore \]Compound interest = Amount \[-\]Principal
    \[=6352.50-5000\]= Rs. 1352.50
