Answer 2

P=₹6500; T=2years;R=9%pa.                                      Interest for 1 year: p= ₹ 6500;t=1year;r=9%        Interest=₹[6500*1*9]/100=₹585.                          Amount= p +interest.                                                =₹6500+₹ 585=₹7085.                                         Interest for 2 year: p=₹7085;t =1 year;r= 9%.        Interest =₹[7085*1*9]/100=₹637.65.                       Amount= p+ interest.                                            =₹7085 +₹637.65 =₹ 7722.65.                                 Hence, compound interest =amount -principle =₹7722.65-₹6500=₹1222.65
