Answer:
Explanation:
From the given information:
The present value of the cash flow of assets and liabilities is:
[tex]P(i) = x(1.05)^1*(1+i)^{-1}+y(1.05)^5 *(1+i)^{-5} -60000*(1+i)^{-3}[/tex]
Thus; [tex]P'(i) =\Big [(-1) (1.05)^1*(1+i)^{-2} \Big] -\Big [y(1.05)^5 *(1+i)^{-6} \Big] + \Big [(3)*60000*(1+i)^{-4}\Big][/tex]
Solving for x&y in the equations P(0.05) = 0 & P'(0.05) = 0
Then;
x+y = (60000) * (1.05)⁻³
x + y = 51830.26
and
x + 5y = 180000* (1.05)⁻³
x + 5y = 155490.7677
x + y = 51830.26
x + 5y = 155490.7677
0 + 4y = 103660.51
4y = 103660.51
y = 103660.51/4
y = 25915.1275
Since y = 25915.1275 and x + y = 51830.26
Then x = 51830.26 - y
x = 51830.26 - 25915.1275
x = $25915.13
Thus, Company XYZ should invest the sum of $25915.13 into Bond X.
