Obvious profit share (5-3)
I believe the answer is:
clear-cut
'obvious' is the definition.
(thesaurus)
'profit share' is the subsidiary indication.
'profit' becomes 'clear' (clearing is a kind of profiting).
'share' becomes 'cut' (cut is a kind of share).
'clear'+'cut'='clearcut'
(Other definitions for clear-cut that I've seen before include "Sharp" , "Very distinct, not open to doubt" , "Distinct and sharply-defined" , "Well-defined" , "Decisive" .)
