Answer and Explanation:
The computation is shown below:
For three months
Simple yield is
= Discount ÷ Price at sale
= 6.07 ÷ 9993.93
= 0.0607%
And, the annualized yield is
= 0.0607% ÷ 3 × 12
= 0.2428%
For 6 months
= Discount ÷ Price at sale
= 23.07 ÷ 9976.74
= 0.2312%
And, the annualized yield is
= 0.2312% ÷ 6 × 12
= 0.4625%
