    The rate of interest on a sum of money is 4% per annum for the first 2 yr, 6% per annum for the next 4 yr and 8% per annum for the period beyond 6 yr. If the simple interest accrued by the sum for a total period of 9 yr is Rs. 2240, what is the sum? 

    A) Rs. 3000                       

    B)  Rs. 4000

    C)  Rs. 5000                      

    D)  Rs. 8000   

    Correct Answer: B

    Solution :

    Sum = Rs. x Then, \[\frac{x\times 4\times 2}{100}+\frac{x\times 6\times 4}{100}+\frac{x\times 8\times 3}{100}=2240\] \[\therefore \]      \[56x=224000\] \[\Rightarrow \]   \[x=\frac{224000}{56}=\]Rs. 4000
