Calculate the amount and compound intrest:-

₹ 8,000 for 1 year at 9% per annum compounded half yearly.​

Answer 1

Answer:

amount- 8720 and C. I - 720

Step-by-step explanation:

p(r/100+1)to the power of no. of years

1. so, 8000(9/100+1) as no. of year is 1 so there will be no power
2. 8000(109/100)
3. 8000*109/100
4. 872000/100
5. 8720

it's simple

Answer 2

Answer:

Amount (A) = Rs8736.20

Compound interest = Rs 836.20

Step-by-step explanation:

As interest is compounded half -yearly , so there will be 2 conversion periods in a year.

So, n = 2,

Rate of interest for 6 months = 1/2 × 9% = 4.5%

$A = P\left(1+\frac{R}{100}\right)^{n}$

$= 8000\times \left(1+\frac{4.5}{100}\right)^{2}$

$=8000\times (1+0.045)^{2}$

$=8000\times (1.045)^{2}$

$=8000\times 1.045\times 1.045$

$=8736.20$

Therefore,.

Compound interest = A-P

= 8736.20 - 8000

= Rs 736.20
