    The difference between the simple interest and the compound interest compounded annually at the same rate on a sum of money at the end of two years is Rs. 152. What is the definite rate per cent per annum?

    A)  5%                              

    B)  7.2%   

    C)         3%                  

    D)         Can't be determined      

    E)  6.7%

    Correct Answer: D

    Solution :

    \[CI-SI=\frac{P{{R}^{2}}}{{{(100)}^{2}}}\]   \[\therefore \]\[152=\frac{P{{R}^{2}}}{{{(100)}^{2}}}\] But the sum is not given. We can't find the rate of interest.
