    A sum of Rs. 15500 is lent out into two parts, one at 8% and another one at 6%. If the total annual income is Rs. 1060, the money lent at 8% is

    A)  Rs. 6500                

    B)  Rs. 7200

    C)  Rs. 8400                              

    D)  Rs. 9000

    Correct Answer: A

    Solution :

     Let the money lent at \[8%\]be Rs. x. Then, \[\frac{x\times 8\times 1}{100}+\frac{(15500-x)\times 6\times 1}{100}=1060\] or            \[2x+93000=106000\] or            \[x=6500\]
