Information with note helping peer group (10)
I believe the answer is:
generation
'peer group' is the definition.
(I've seen this before)
'information with note helping' is the wordplay.
'information' becomes 'gen' (gen can informally mean information).
'with' is a charade indicator (letters next to each other).
'note' becomes 'e' (musical note).
'helping' becomes 'ration' (a ration is a serving or helping).
'gen'+'e'+'ration'='GENERATION'
(Other definitions for generation that I've seen before include "People of the same age" , "Group born around same time" , "About thirty years'" , "group of similar age" , "what was lost in WW1" .)
