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

Given :--

• Principal = Rs.8000
• Rate = 5%
• Time = 2(1/2) years.

To Find :-

• Amount and compound interest ?

Solution :-

Assume Time whole As = W .

And, Fraction Time as = F .

Than,

Formula for Amount will be :-

☛ Amount = P [ 1 + (R/100) ]^W * [ 1 + {(F*R)/100} ]

Putting Values we get,

→ A = 8000 [ 1 + (5/100) ]² * [ 1 + (5/2*100) ]

→ A = 8000 * (21/20)² * (41/40)

→ A = (8000 * 441 * 41)/ (400*40)

→ A = Rs.9040.5

So,

→ CI = Amount - Principal

→ CI = 9040.5 - 8000

→ CI = Rs.1040.5

Hence, Amount is Rs.9040.5 and Compound interest is Rs.1040.5.
