Question

Find the amount and compound interest on ₹8000 at 7%per annum for 3 years.

Answer 1

How mate!!


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.



Hope it helps you

Answer 2

Answer:

amount:8820

Compound Interest:820

Step-by-step explanation:

Principal = 8000

rate = 5%

time = 2 years

The formulae is

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

So

= 8000(1+5/100)²

= 8000* (1+1/20)²

= 8000 *( 21/20)²

= 8000 * 441/400

= 20 * 441 =8820

Formulae to Compound interest is A-P. that is

CI:Amount - principal

   =8820-8000

    =820

So u will get the answers as

Amount=8820 and C.I=820 Rps
