Present value of annuity=Annuity[1-(1+interest rate)^-time period]/rate

2000=734.42[1-(1.05)^-n]0.05

2000=14688.4[1-(1.05)^-n]

1-(1.05)^-n=(2000/14688.4)

(1.05)^-n=1-(2000/14688.4)

(1/1.05)^n=0.86383813

Taking log on both sides;

n*log(1/1.05)=log0.86383813

Hence n=log0.86383813/log (1/1.05)

=
3 years(Approx).
