CREATE TABLE table_name_24 (attendance INT, record VARCHAR, average VARCHAR)

What's the mean attendance number when the record is 12-4 and the average is less than 10,027?
SELECT AVG(attendance) FROM table_name_24 WHERE record = "12-4" AND average < 10 OFFSET 027
SELECT AVG("attendance") FROM "table_name_24" WHERE "12-4" = "record" AND "average" < 10 OFFSET 027
