CREATE TABLE table_40497 ("Date" TEXT, "Score" TEXT, "Set 1" TEXT, "Set 2" TEXT, "Set 3" TEXT, "Set 4" TEXT, "Set 5" TEXT, "Total" TEXT)

What is Total, when Set 5 is NA, and when Set 2 is 25-13?
SELECT "Total" FROM table_40497 WHERE "Set 5" = 'na' AND "Set 2" = '25-13'
SELECT "Total" FROM "table_40497" WHERE "Set 2" = '25-13' AND "Set 5" = 'na'
