A. 3162.75
B. 4125.00
C. 4155.00
D. 5100.00
E. 5355.00

Correct Answer : Choice C. Rs.4155.00

Explanatory Answer
Interest payable @ the end of the first year @ 5% interest on Rs 6000 =

Amount payable @ the end of the first year = Rs 6000 + Rs 300 = Rs 6300
Amount paid @ the end of the first year = Rs 1200
Therefore, Principal for the second year = Rs 6300 – Rs 1200 = Rs 5100

Interest payable @ the end of the second year @ 5% interest on Rs 5100 =

Amount payable @ the end of the second year = Rs 5100 + Rs 255 = Rs 5355
Amount paid @ the end of the second year = Rs 1200
Therefore, Principal for the third year = Rs 5355 – Rs 1200 = Rs 4155

Thus, the amount of loan outstanding at the beginning of the third year = Rs 4155.
