Answer:

duration of the portfolio 2.11

Step-by-step explanation:

We will do weighted-average

Bond A represent 300,000/1,000,000 = 3/10 and has a duraction of 2 years

so 3/10 x 2 = .6

Bond B represent 300,000/1,000,000 = 3/10 and has a duraction of 1.7 years

son 3/10 x 1.7 = 0.51

Bond C represent 400,000/1,000,000 = 4/10 and has a duraction of 2.5 years

so 4/10 x 2.5 = 1

now we add the weighted together: .6 + .51 + 1 = 2.11
