Step-by-step explanation:

amount= p(1+r/100)^n

= ₹ 8000(1+5/100)^2

=₹ 8000(1+1/20)^2

=₹ 8000(21/20)^2

=₹ 8000×21/20×21/20

= ₹ 20×21×21

=₹ 8820

compound interest=₹ (8820 - 8000) =₹ 820

Answer:

Finding amount on:-

P = 8000

R = 5% p.a. compounded annually

T = 2 years OR n= 2

Step-by-step explanation:

Amount (A) = P(1+R/100)^2

A=8000(1+5/100)^2

A= 8000(1+1/20)^2

A= 8000(20+1/20)^2

A = 8000(21/20)^2

A= 8000×21/20×21/20

A = 80×21/2×21/2

A = 40×21×21/2

A = 20×21×21

A= 20×441

A = 8820

So, the amount is Rs. 8820.

Now, we have to find the compound interest on given principle :-

Compound Interest (C.I.)= Amount(A) - Principal(P)

C.I. = 8820 - 8000

C.I. = 820

So, the compound interest is of Rs. 820.

Amount = Rs. 8820

Compound interest = Rs. 820.
