Read Solution (Total 2)
-
- 20%
if r% is annual rate of C. interest , then
4500 = 3125*(1+r/100)^2
(1+r/100)^2 = 1.44
(1+r/100)=1.2
r/100 =0.2
r=20 - 13 years agoHelpfull: Yes(3) No(0)
- P=3125,A=4500 n=2years, r=?
Substituting the above values to find r:
4500=3125*(1+r/100)^2
(100+r)^2=14400
100+r=120
r=20, Hence the rate of CI is 20% - 13 years agoHelpfull: Yes(1) No(0)
