Table schema:
CREATE TABLE table_name_84 (number_of_branches INTEGER, on_site_atms VARCHAR, off_site_atms VARCHAR)

Question: What is the total number of branches when the on-site ATMS is 1548, and the off-site ATMs is bigger than 3672?
SQL: SELECT SUM(number_of_branches) FROM table_name_84 WHERE on_site_atms = 1548 AND off_site_atms > 3672
