CREATE TABLE table_name_61 (mpg_us_urban NUMBER, mpg_uk_urban__cold_ VARCHAR2, mpg_uk_extra_urban VARCHAR2)

What's the mpg-US urban when the mpg-UK urban is 20 and the mpg-UK extra urban is less than 37.2?
SELECT SUM(mpg_us_urban) FROM table_name_61 WHERE mpg_uk_urban__cold_ = 20 AND mpg_uk_extra_urban < 37.2
SELECT SUM("mpg_us_urban") FROM "table_name_61" WHERE "mpg_uk_extra_urban" < 37.2 AND "mpg_uk_urban__cold_" = 20
