    D)  Rs.106060.10 and Rs. 6060.10

    Correct Answer: C

    Solution :

    P = Rs. 100000 Time, T = 9 months = 3 quarter yr R =4% per annum = 1 % quarterly \[\therefore \]\[A=100000{{\left( 1+\frac{1}{100} \right)}^{3}}=100000{{\left( \frac{101}{100} \right)}^{3}}\] \[=100000\times \frac{101}{100}\times \frac{101}{100}\times \frac{101}{100}\]= Rs. 103030.10 Also, compound interest\[=A-P\]=Rs. 103030.10 \[-\]Rs. 100000 Compound interest = Rs. 3030.10
