Last year in a group of 30 businesses, 21 reported a net profit and
did not report a net profit nor invest in foreign markets last year?

reported a net profit and had invest-
ments in foreign markets.
(2) last year 24 of the 30 businesses
reported a net profit or invested in
foreign markets, or both.
Statement (1) ALONE is sufficient, but statement (2) alone is not sufficient
 Statement (2) ALONE is sufficient, but statement (1) alone is not sufficient
