Table schema:
CREATE TABLE table_name_1 (floor VARCHAR, pommel_horse VARCHAR, position VARCHAR, total VARCHAR)

Question: What is the score of the floor when the position is less than 21, and less than 81.2 total, and the pommel horse score is 13.925?
SQL: SELECT floor FROM table_name_1 WHERE position < 21 AND total < 81.2 AND pommel_horse = "13.925"
