Final answer:
The current yield of the bond is 9.22% and the yield to maturity requires more complex calculations.
Step-by-step explanation:
To calculate the current yield of the bond, we need to divide the annual interest payment by the current market price of the bond. In this case, the annual interest payment is $1000 * 8.3% = $83, and the current market price is $900. Therefore, the current yield is $83 / $900 = 0.0922 or 9.22%.
To calculate the yield to maturity of the bond, we need to consider the interest payments and the capital gains or losses that will be realized until the bond matures in 10 years. This calculation can be complex and requires considering the time value of money. It's best to use financial calculator or software to calculate the yield to maturity.
