Answer #1
  • 1. The formula for simple Interest is S= P+P*R*T, S= value after doubling, p= principal, r= rate of interest, t= time period. Let amount invested is $100, therefore
  • 200= 100+100*11%*T
  • T= 9.09 years i.e. approximatelt 9 years
  • The formula for compound interest is S= P(1+R)^t
  • 200= 100(1+0.11)^t
  • Solving, T comes out to be approximately 7 years
