Question

p=1000
R=4%
T=1year
compunded half yearly​

Answer 1

Step-by-step explanation:

when compunded half yearly multiply year by 2 and divide rate by 2

amount = p(1+ r/ 2 x 100)^2n

= 1000(1 + 4 / 2 x100) ^ 2 x 1

= 1000( 1 + 1 / 50)^2

= 1000( 51 / 50)^2

= 1000 x 51 / 50 x 51 / 50

= 2 x 51 x 51 / 5

= 1040.4

compund interest = amount - principle

= 1040.4 - 1000

=40.4
