问题如下：
Based on Exhibit 1, which short position is most likely to be included in the condor outlined in Scenario 2?
选项：
A.1-year $338 million
B.5-year $71 million
C.10-year $38 million
解释：
A is correct.
To profit from a decrease in yield curve curvature, the correct condor structure will be: short 1s, long 5s, long 10s, and short 30s. The positions of the condor will be: short $338 million 1-year bond, long $71 million 5-year bond, long $38 million 10-year bond, and short $17 million 30-year bond.
This condor is structured so that it benefits from a decline in curvature, where the middle of the yield curve decreases in yield relative to the short and long ends of the yield curve.
To determine the positions, we take the maximum allowance of 30-year bonds of $17 million and determine money
duration. Money duration is equal to market value x modified duration divided by 100. 30-year bond money duration = $17 million × 19.69/100 = $3,347,300. The market values of the other positions are:
1-year bond: $3,347,300 × 100/0.99 = $338.11 million or $338 million
5-year bond: $3,347,300 × 100/4.74 = $70.62 million or $71 million
10-year bond: $3,347,300 × 100/8.82 = $37.95 million or $38 million
两个问题：
1、money duration=moneyXmodified duration/100，这个公式是怎么得到的。
2、Exibit 2里有PVBP的值，我使用PVBP计算，1年期的要买约335，和答案有些出入，但是5年期和10年的很接近。这种题如果出上午题应该使用那个变量计算？
不知道我的问题是否清楚，谢谢！
