    C Rs 1520 Correct Answer Incorrect Answer
    D Rs 1320 Correct Answer Incorrect Answer

    Solution

    Rate of interest = 4/2 = 2% (semi annually) Interest = Rs 1030.402 for given time, not for 1 year, but the whole time. Now, C.I = 12500 + 1030. 402 = 13530.402 Then, 12500 [1 + 2/100] n = 13530.402 [51/50]n= 6765201/6250000 So, n = 4 [semi-annually] which means actual time = 4/2 = 2yearsthen, Amount compounded annually = 12500 [1 + 4/100]2 = Rs 13520 Now, C.I = 13520 - 12500 = Rs 1020
