Table schema:
CREATE TABLE table_name_3 (code INTEGER, place VARCHAR, area__km_2__ VARCHAR, population VARCHAR, most_spoken_language VARCHAR)

Question: What is the lowest code number for the remainder of the municipality that has an area bigger than 15.34 squared kilometers, a population greater than 762 and a language of xhosa spoken?
SQL: SELECT MIN(code) FROM table_name_3 WHERE population > 762 AND most_spoken_language = "xhosa" AND area__km_2__ > 15.34 AND place = "remainder of the municipality"
