Difference b/w the compound interest and simple interest for Rs.2500 for 2 years is given. find the rate of interest.

• 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,
  Data inadequate!

• 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)
