Rupee spent on pulp (5)
I believe the answer is:
puree
'pulp' is the definition.
(I have seen 'Smooth pulp ' mean 'puree' so perhaps 'pulp' could also mean 'puree')
'rupee spent' is the wordplay.
'spent' is an anagram indicator.
'rupee' is an anagram of 'PUREE'.
'on' is the link.
(Other definitions for puree that I've seen before include "Pulped fruit or vegetables" , "Smooth pulped food" , "process" , "Liquidised fruit/veg pulp" , "Pulped fruit/veg" .)
