Placed duties at random (8)
I believe the answer is:
situated
'placed' is the definition.
(situating is a kind of placing)
'duties at random' is the wordplay.
'random' is an anagram indicator.
'duties'+'at'='dutiesat'
'dutiesat' is an anagram of 'SITUATED'.
(Other definitions for situated that I've seen before include "Placed or located in certain position" , "Positioned" , "Located; put into position" .)
