Solve the following problems in picture.

1. We are considering two bonds. One pays 3% and has a maturity of 8 years, while the other pays 4% and has a maturity of 8 years. If we expect rates to fall by 1% from their current level, which is 4%, where should we invest, and what is the total ROR we make for the one versus the other? (Note the first bond drops only .5%, while the second required rate drops by 1%) 2. We expect the yields of maturity to increase by 1% from their present level. We have a 25 year 8% paying bond with a required rate of 7%. We want to switch to a 4 year 8% bond with a market rate of 6%. What shall we gain if we act on our expectation, and it transpires. If rates instead increase, what will be the result? 3. We have a debt of $10 million in 15 years. If we want to ascertain that we have enough to meet this debt in 15 years, what year to maturity bonds should we invest in, if they pay 9% annually, and they have a ytm of 4%
