Table schema:
CREATE TABLE table_name_42 (mpg_uk_combined INTEGER, l_100km_urban__cold_ VARCHAR, mpg_uk_urban__cold_ VARCHAR, l_100km_extra_urban VARCHAR)

Question: What's the least mpg-UK combined when the mpg-UK urban is 25.4, the L/100km extra urban is less than 6.9 and the L/100km urban is more than 11.1?
SQL: SELECT MIN(mpg_uk_combined) FROM table_name_42 WHERE mpg_uk_urban__cold_ = 25.4 AND l_100km_extra_urban < 6.9 AND l_100km_urban__cold_ > 11.1
