    Answer : Option C

    Explanation :

    Amount=Rs.[25000\(*(1+\frac { 12 } { 100 } )^3]\)

                 

                =Rs.[25000\(*\frac {28 } { 25 } \)\(*\frac {28 } { 25 } \)\(*\frac {28 } { 25 } \)]

                 

               = Rs. 35123.20

     

      C.I. = Rs. (35123.20 - 25000) = Rs. 10123.20
