Answer:
Option D $8333
Explanation:
The value of the irredeemable bond can calculated using the Dividend Valuation Model.
The formula for the computation is:
Value of the Bond = Interest paid / rate of return on a similar bond
Value of the Bond = $500 / 6% = $8333.33
Note that initially the bond was worth $5000 which can be calculated with the same formula:
Value of the Bond = $500 / 10% = $5000
The net increase is $3333
So the correct answer is option D.
