Kid a fellow a hundred per cent (5)

I believe the answer is:

total

I'm a little stuck... Click here to teach me more about this clue!

'a hundred per cent' is the definition.
I can't judge whether this defines the answer.

'kid a fellow' is the wordplay.
'kid' becomes 'tot' (tot is a kind of kid).
'a fellow' becomes 'al' (man's name).
'tot'+'al'='TOTAL'

Can you help me to learn more?

(Other definitions for total that I've seen before include "Utter" , "Completely destroy" , "It might be grand" , "Final tally" , "Count" .)

I've seen this clue in the Evening Standard.
