CREATE TABLE table_204_39 (id DECIMAL, "number" DECIMAL, "symbol" TEXT, "name" TEXT, "21st" DECIMAL, "22nd" DECIMAL, "23rd" DECIMAL, "24th" DECIMAL, "25th" DECIMAL, "26th" DECIMAL, "27th" DECIMAL, "28th" DECIMAL, "29th" DECIMAL, "30th" DECIMAL)

SELECT COUNT("symbol") FROM table_204_39 WHERE "symbol" <> 'kr' AND NOT "30th" IS NULL
SELECT COUNT("symbol") FROM "table_204_39" WHERE "symbol" <> 'kr' AND NOT "30th" IS NULL
