Interest rate risk is associated with the bonds price variability given a change in the interest rates.

Suppose you have BOND A, which is a 30 year zero coupon bond and BOND B, which is a 5 year 10% coupon bond. If interest rates (YTM) change from 8% to 7% the bonds will increase in value. Suppose BOND A's price changes from $99.38 to 129.64 and the 5 year 10% coupon bond price changes from $1079.85 to $1123.01. Which bond has the greatest percentage increase in value? Record the percentage increase in value of the bond with the highest percentage change below. Write the increase as a decimal, so a 5% increase would be written as 0.0500.
