Question

Find the amount and the compound intrest on 8000 at 5 % per annum for 2 yrs​

Answer 1

Answer:

Step-by-step explanation:

Formula For compound interest

$C.A= Principal*(1+\frac{Rate}{100} )^{Time}$

So, I am Given that:-

Principal= 8000

Rate=5 % p.a

Time= 2 years

To find

1. Amount
2. Compound Interest

Solution

By using the above formula

$C.A=8000*(1+\frac{5}{100} )^{2}$

So, I get my Compound Interest as 9724.05

Also we know that

$Amount = C.A - Principal$

So, Amount= 9724.05-8000

Amount= 1724.05

Question:☆

Find the amount and the compound intrest on 8000 at 5 % per annum for 2 yrs

Step to step explanation:

• $\sf{p = 8000}$
• $\sf{r = 5\%}$
• $\sf{t = 2years}$

$\rm \red{now \: the \: formula}$

$\bf{{ \boxed{ \green{ \tt{A = p[1 + \frac{R}{100] \: }}}}}}$

• p is principal
• r is rate
• t is time

from the formula we used

$\tt{A = 8000 \times (1 + \frac{5}{100 })^{2} }$

$= \tt{8000 \times (1 + \frac{5}{100} )}^{2}$

$= \tt{8000 \times( 1 + \frac{5}{100}) }^{2}$

$= \tt{8000 \times (1 + \frac{1}{20}) }^{2}$

$= \tt{8000 = ( \frac{21}{22}) }^{2}$

$\tt{ = 8000 \times \frac{441}{200}}$

$\tt{ = 20 \times 441}$

$\tt \green{ = 8820}$

______________________________

Now again use the formula

$\bf{ \: { \boxed{ \red{ \tt{CI = Amount - principal \: }}}}}$

$\rm{ = 8820 - 8000 = 820}$

$\rm \red{ = 820}$

I hope it's help uh
