If Compound Interest on a certain sum for 2 years @ 5% p.a. is Rs. 328, the Simple interest will be ?

• 320 Rs.
  p(1+ 5/100)^2 - p= 328
  p[(105/100)^2 -1]= 328, p=328/0.1025 =3200
  Simple interest @ 5% p.a for 2 years = 3200*2*5/100 =320

• Rs 320.
  
  If x is the principal amt, then
  x*(21/20)^2= x+328
  x*41/400=328
  x= Rs 3200
  
  Then S.I= 3200*5*2/100 = Rs 320
