a sum of money grows to 144/121 times when invested for 2yrs in a scheme where interest is compounded yearly.how long will the same sum of money take to treble if invested at the same rate of interest in the scheme where interest is computed under s.i method?

• 144*p/121 = p(1+ r/100)^2
  so r =100/11
  now 2p = p*r*t/100
  put value of r.
  so t=22 years answer.
