year at the rate of 20%per anum if the interest compounded quartely​

Answer 1

Answer:

SI = P×T ×R

-----------

100

SI = 2000× 1 × 20

----------------

100

=400

Answer 2

Answer:

a=2431.0125 CI=431.0125

Explanation:

a=p×(1+r/400)^4n

CI=a-p

We have

p=2000

r=20%

t=1=4quarters

a=2000 (1+20/400)^4

2000×(1+1/20)^4

2000(21/20×21/20×21/20×21/20)

=21×21×21×21/80

=2431.0125

CI=2431.0125-2000

=431.0125
