P is Periodic payment monthly = $ 1,000 /- | ||||||
r is Rate of Interest = ? | ||||||
n is No of months = 132 Months | ||||||
Present Value of Annuity is = $ 90,000 /- | ||||||
90000=(1000*(1-(1+r)^-132)/r) | ||||||
1-(1+r)^-132/r=90 | ||||||
Using trail and error "r" is computed as | ||||||
Annual interst rate "r" is 6.5202% Approx. | ||||||
