Question

find the amount and the compound interest on rupees 8000 for 2 years at 6 percent per annum, compounded annually
​

Answer 1

Answer:

=. 820.

Step-by-step explanation:

principal = 8000

rate = 5%

time = 2 years ( 2 terms)

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

= 8000(1+5/100)²

= 8000* (1+1/20)²

= 8000 *( 21/20)²

= 8000 * 441/400

= 20 * 441 = 8820 /-

:. CI = Amount - Principal

= 8820 - 8000

=. 820.

Answer 2

Answer:

Here, p = 8000 rs. , r= 6% , n = 2 years

using the formula, A (Amount)= p (1+r/100)^n,

A = 8000 (1+6/100)^2

= 8000 (106/100)^2

= 8000×106/100 × 106/100

= 44944 rs.

Therefore, C.I.= A - P = 44944 - 8000

= 36944 Rs.
