    Solution

    Rate of interest (more) =5%  T=3 years  Final Rate of interest (more) = 5*3 =15%  The interest receives more=3600*(15 /100) = Rs.540  This satisfies the above condition.  From option (B)  Rate of interest (more) =5%  T=3 years  Final Rate of interest (more) = 5*3 =15%  The interest receives more = 1440*(15/100) = Rs.216  This does not satisfy the above condition.  From option (C)  Rate of interest (more) =5%  T=3 years  Final Rate of interest (more) = 5*3 =15%  The interest receives more=3500*(15 /100) =Rs.525  This satisfies the above condition.  From option (D)  Rate of interest (more) =5%  T=3 years  Final Rate of interest (more) = 5*3 =15%  The interest receives more=2400*(15 /100) =Rs.360  This does not satisfy the above condition.
