1.  Sam invested ₹ 15000 @ 10% per annum for one year. If the interest is compounded half-yearly, then the amount received by Sam at the end of the year will be:
A. ₹ 16,500
B. ₹ 16,525.50
C. ₹ 16,537.50
D. ₹ 18,150
E. None of these

Answer: Option C

Explanation:

P = ₹ 15000; R = 10% p.a. = 5% per half-year; T= 1 year = 2 half-years.

Amount:

= ₹ 15000 x 1 + 5 2
100
= ₹ 15000 x 21 x 21
20 20
= ₹ 16537.50
