Question

find the amount and the compound interest on 8000 at 5% per annum for 2 years please explain don't spam​

Answer 1

P(Principal amount) = 8000 rs, R(rate of interest per annum) = 5%, n(number of years) = 2yrs

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

= 8000(1 + 5/100)^2

= 8000(105/100 x 105/100)

= 8820 rs : Ans

CI(Compound Interest) = A - P

= 8820- 8000 = 820 : Ans

Answer 2

Answer

• Amount = Rs. 8820
• Compound Interest = 820

Step-by-step explanation:

Given:

• Principal amount = Rs. 8000
• Rate = 5%
• Time = 2 years

To Find:

• Amount
• Compound Interest (CI).

Now, we know that,

=> Amount = P[1 + (R/100)]ⁿ

=> Amount = 8000[1 + (5/100)]²

=> Amount = 8000[1 + (1/20)]²

=> Amount = 8000[(20 + 1)/20]²

=> Amount = 8000(21/20)²

=> Amount = 8000 × 441/400

=> Amount = 20 × 441

=> Amount = Rs. 8820

Hence, Amount = Rs. 8820.

Now, we will calculate Compound Interest (CI).

=> CI = Amount - Principal Amount

=> CI = 8820 - 8000

=> CI = Rs. 820

Hence, CI = 820
