Answer:
B. 8.08.
Explanation:
Use the following formula to calculate the duration of the bond
Change in Bond Price / Current Price = -Duration x Change in Yield on the bond
-Duration = ( Change in Bond Price / Current Price ) / Change in Yield on the bond
Where
Change in price of the bond = $1,030 - $1,050 = -$20
Current Price = $1,050
Change in Yield on the bond = 25 / 100 = 0.25%
Placing values in the formula
-Duration = ( -$20 / $1,050 ) / 0.25%
-Duration = -7.6
Duration = 7.6
Now use the following formula to calculate the yearly duration
Duration = Duration x ( 1 + Yield on the bond ) = 7.6 x ( 1 + 6.25% ) = 8.08
