CREATE TABLE table_36168 ("1950" FLOAT, "1960" FLOAT, "1970" FLOAT, "1980" FLOAT, "1990" FLOAT, "1996[2]" FLOAT)

1996[2] of 127, and a 1990 smaller than 120 is the sum of 1990?
SELECT SUM("1980") FROM table_36168 WHERE "1996[2]" = '127' AND "1990" < '120'
SELECT SUM("1980") FROM "table_36168" WHERE "1990" < '120' AND "1996[2]" = '127'
