Table schema:
CREATE TABLE table_name_36 (position INTEGER, played VARCHAR, goal_difference VARCHAR, drawn VARCHAR, lost VARCHAR)

Question: What is the sum of the positions for the player who had less than 25 losses, a goal difference of +20, 10 draws, and played less than 42?
SQL: SELECT SUM(position) FROM table_name_36 WHERE drawn = 10 AND lost < 25 AND goal_difference = "+20" AND played < 42
