Question

Find the amount and the compound interest on Rs.8000 at 5% per annum,for 2 years compunded annually.



It's urgent I'll give 20 points

Answer 1

A = P(1+R/100)^n
CI = A - P
A = 8000(1+1/20)^2
A = 8000 × 21/20×21/20
A = 20×21×21
A= 8820
CI = 820

Answer 2

$= > amount = principal \: {(1 + \frac{rate}{100} )}^{time} \\ \\ = > a = p \: {(1 + \frac{r}{100} )}^{t} \\ \\ = > a = 8000 \: {(1 + \frac{5}{100}) }^{2} \\ \\ = > a = 8000 \: {( \frac{20 + 1}{20} ) }^{2} \\ \\ = > a = 8000 \times \frac{21}{20} \times \frac{21}{20} \\ \\ = > a = 20 \times 21 \times 21 \\ \\ = > a = 8820$
