You want the value of those 2 query fields combined? Should be able to do that using a 3rd query field that combines their selects. See the below example based off the queries provided above.
Code:
SELECT ( ( `cb_uktfrpaxout` * 10 ) + ( `cb_uktfrpaxin` * 10 ) ) FROM `#__comprofiler` WHERE `id` = '[user_id]'
Query field should be able to display on profile edit as well assuming you've it set to do so within CB > Field Management and have latest build of CB Query Field.
