问题如下：
The table provides relevant information about four bonds in a portfolio, based on the table, the price value of a basis point for this portfolio is close to?
选项：
A.$65,341.15.
B.$77,518.65.
C.$73,124.38.
D.$72,647.90.
解释：
D is correct
考点：Bond Duration-DV01
解析：
effective duration=7.54
x 0.0001 x 96.35×1000000 = $72,647.9
这道题的用effective duration进行计算，但是每个effetive的比例用市值计算（25/100）这样
但是计算出来的effective duration应该是7.5850吧？
烦请展示计算过程

NO.PZ2019070101000092 这道题为什么不考虑convexity呢
NO.PZ2019070101000092 请问是mofieration还是effective ration？
