Read Solution (Total 2)
-
- SI = Simple Interest = PNr
CI = Compount Interest = P(1+r)N
SI - CI = 2500
PNr - P(1+r)N = 2500
N = 2 (given)
So, 2Pr - P(1+r)2 = 2500
To Find: r
Since, we do not have the value of P,

- let difference d;
P= d(100/r)2
r=100*(sq root (d/P))sq root
r=100*(sq root (d/2500))
r=2* sq root of (d) - 14 years agoHelpfull: Yes(6) No(9)
