Compound interest after 1 year = same as simple interest = 
           = Rs 9, 600 * 10/100 * 1 = Rs 960

Compound interest earned during 2ng year = simple interest + interest on interest
            = Rs 960 + Rs 960 * 10/100 * 1 = Rs 1,056
total compound interest earned in two years = Rs  2, 016

compound interest during 3rd year 
        = simple interest + interest on interest 
           = Rs 960 + Rs 1, 056 * 10/100 * 1 
             = Rs 1, 065.60

Total compound interest earned  in 3 years  = Rs 3, 081.60
