Question

find the compound interest p=25000 r=8 n=2

Answer 1

a=p(1+r/100)
a=25000(1+8/100)2
a=25000*108/100*108/100
a=291600/10
a=29160
ci=29160-25000
ci=4160


hope it helps u.

Answer 2

CI = 25000{(1+8/100)^2-1}
= 25000{(27/25)^2-1}
= 25000{(27)^2 - (25)^2/(25)^2}
= 25000{729 - 625/625}
= 40*104
= 4160
