    Anirudh deposited two parts of a sum of Rs. 25000 in different cooperative banks at the rates of 15% per annum and 18% per annum respectively. In one year he got Rs.  4050 as the total interest. What was the amount deposited at the rate of 18% per annum?

    A)  Rs. 15000

    B)                     Rs. 10000

    C)  Rs. 9000                      

    D)  Data inadequate

    Correct Answer: B

    Solution :

    Amount deposited at 18% per annum = Rs. x
    \[\therefore \] A mount deposited at 15% per annum = Rs. \[(25000-x)\]
    Interest in one year
    \[=\frac{x\times 18\times 1}{100}+\frac{25000-x\times 15\times 1}{100}\]
    \[=\frac{18x}{100}+\frac{375000+15x}{100}=\frac{3x}{100}=3750\]
    According to question,
    \[\frac{3x}{100}+3750=4050\Rightarrow \frac{3x}{100}=300\]
    \[\therefore \]                  \[x=10000\]
