Answer 2

Answer:

Compound interest = 8820 - 8000

Step-by-step explanation:

Given : A sum of rs 8000 for 2 years at 5% per annum compounded annually.

To find : The compound interest ?

Solution :

The compound interest formula,

$A=P(1+r)^t$

Principal=8000

Rate = 5%=0.05

Time = t= 2 years

Substitute the values,

$A=8000(1+0.05)^2$

$A=8000(1.05)^2$

$A=8000\times 1.1025$

$A=8820$

The amount is Rs.8820.

Compound Interest = Amount -Principal

Compound interest = 8820 - 8000

Compound Interest = Rs.820.
