- B. Rs 18973
- C. Rs 19448
- D. Rs 19880
Explanation
At 10% annually compounded half-yearly, the rate per half-year is 5%, and 2 years contain 4 periods. The amount is 16,000 Rs x (1.05)^4 = 19,448.10 Rs, approximately 19,448 Rs. Students may choose 18,973 Rs by applying 10% only twice instead of applying 5% four times.
