Answer 2

Answer:

The answer is Rs. 12610

Step-by-step explanation:

Interest is compounded half yearly, so the effective rate of interest every 6 months is 5%.

So as per Compound Interest Formula  = P(1+r/100)t - P

P = 80000

r = 5

t = 3 (18 months = 3 half years)

Amount = 80000(1.05)^3 - 80000 = 12610
