Perfect business transaction with Apple? (5)
I believe the answer is:
ideal
'perfect' is the definition.
(similar in meaning)
'business transaction with apple?' is the wordplay.
'business transaction' becomes 'deal' (I've seen this before).
'with' means one lot of letters go next to another.
'apple?' becomes 'i' (I can't justify this - if you can you should give a lot more credence to this answer).
'deal' after 'i' is 'IDEAL'.
(Other definitions for ideal that I've seen before include "Paradigm" , "Conceptual" , "Paragon" , "Consummate" , "existing only in imagination" .)
