Answer:
fair value is $761 
Step-by-step explanation:
Given data 
bond value = $1000
rater r = 12 %
rate R = 16% 
time = 20 year 
to find out 
a fair price
solution
we know compounding period in year is = 4 
so time 20 x 4 = 80 
fair Price = 
 [(Quarterly Coupon) / (1 + R/400)^t] +bond value / (1 + R /400)^t
 [(Quarterly Coupon) / (1 + R/400)^t] +bond value / (1 + R /400)^t
here 
Quarterly Coupon = 12 × 1000/400 = 30
so
fair Price = 
 [(30) / (1 + 16/400)^k] + 1000 / (1+16/400)^80
 [(30) / (1 + 16/400)^k] + 1000 / (1+16/400)^80
solve it we get 
fair value is $761
