Question

find the compound interest when it is compounded annually (i) p =rupees 3200 ​

Answer 1

Step-by-step explanation:

Compound interest=6250

Answer 2

Answer:

1) P = 8000 , R = 5% , Time(n) = 3 years

Amount = P( 1+R/100)

= 8000(1+5/100)

=. 8000(105/100)

=. 8000(21/20)

=. 8000 x 21/20

=. 400 x 21

=. 8400.

Compound Interest = A - P

= 8400 - 8000

= 400.

2). P = 3200 , R = 25% , Time(n) = 3 years

Amount = P(1+R/100)

= 3200(1+25/100)

= 3200(125/100)

= 3200 x 25/20

= 160 x 25

= 4000.

Compound Interest = A - P

= 4000 - 3200

= 800.
