Answer:
7.37%
Explanation:
First of we calculate Future value of coupon payments:
Annual Payment= 65
Interest = 6%
Time = 5 years
Present value = 0
Future value = 65 + 65 * (1.06) + 65 * (1.06)^2 + 65 * (1.06)^3 + 65 * (1.06)^4
Future value = 366.41
Now after 5 years the interest rate will become 7%, we will calculate present value of bond after 5 years:
Annual Payment= 65
Interest = 7%
Time = 15 years
Present value = 65/ (1.07) + 65/ (1.07)^2 + .......+ 65/(1.07)^15 + 1000/ (1.07)^15
Present value = 954.46
Total future value = 954.46 + 366.41 = 1,320.87
($925.50) * (1 + r)^5 = $1,320.87
r = 7.37%
