CREATE TABLE table_62795 ("Number" TEXT, "Previous Number ( s ) " FLOAT, "Previous Class" TEXT, "Converted" FLOAT, "Withdrawn" FLOAT, "Disposal" TEXT)

With a number of 30, what would be listed for previous number(s)?
SELECT "Previous Number(s)" FROM table_62795 WHERE "Number" = '30'
SELECT "Previous Number(s)" FROM "table_62795" WHERE "Number" = '30'
