Work out, starting on dumbbells - it's how they got the figures? (10)
I believe the answer is:
calculated
'dumbbells it's how they got the figures?' is the definition.
The definition suggests an adverb but the answer is not.
'work out starting' is the wordplay.
'work out' becomes 'calculate' (I've seen this before).
'starting' becomes 'd' (I can't explain this - if you can you should give a lot more credence to this answer).
'calculate'+'d'='CALCULATED'
'on' is the link.
Can you help me to learn more?
(Other definitions for calculated that I've seen before include "Worked out" , "Statistics are" , "Done with an eye on the likely consequences" , "Deliberate" , "purposeful" .)
