The simple interest accrued on an amount of Rs.40,000 at the end of three years is Rs.12,000.What would be the compound interest accrued on the same amount at the same rate in the same period?

• 12000/3=4000
  4000/40000*100=10% rate,so in compound intrest amount to principal ratio is=(11/10)^3..ie.1331/1000
  if we want to find CI thn...(1331-1000)/1000*40,000....u ll get CI=13240
  and amount=13240+40000=53240

• SI=(P*R*T)/100; 40000=(12000*3*R)/100
  R=10% APPLYING THE FORMULA OF CI=P(1+(R/100))/^N
  THUS CI=53240

• CI=A+P
  A=53240
  CI=53240+40000
  =93240

• Here S. I. =C. I.
  SO 4000 ON first year
  4000+400 on 2nd year
  4000+400+400+40 on 3rd year
  Count all these, we get 13240
