Question

He has lost ------- his wealth

Answer 1

He has lost with his wealth

Answer 2

He has lost all his wealth.

A quick FYI :

Here 'all' is used as a determiner. It literally means 'every one' , 'the complete number of amount' or 'the whole'.

'All' is most often used as a determiner. We can use a countable or an uncountable noun after it.

For Ex: 'All my friends are away at university'.
