Q32.
Last year in a group of 30 businesses, 21 reported a net profit and
15 had investments in foreign markets. How many of the businesses
did not report a net profit nor invest in foreign markets last year?
(1) last year 12 of the 30 businesses
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.
雖然這題常出現,但還是有個地方想不通
這題答案是B,我覺得第(1)個條件也沒有錯
我的想法:∵12人兩者都有,∴只report a net profit:9人,只investment in foreign
market:3人
都沒有的:30-12-9-3=6
想請問這個想法有什麼盲點嗎?
感謝解惑!!!
