In the 2018 question, it stated money duration = modified duration × market value.
but in the 2010 question, it is instead stated money duration = modified duration × market value /100 which is in line with the text book 3.2.1.1 in reading 24, it states “Money duration is market value multiplied by modified duration, divided by 100”
anyone knows why the 2018 question is the exception?
