rishikha Posted July 3, 2007 Share Posted July 3, 2007 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 investments in foreign markets. (2) last year 24 of the 30 businesses reported a net profit or invested in foreign markets, or both. OA B Quote Link to comment Share on other sites More sharing options...
hjafferi Posted July 3, 2007 Share Posted July 3, 2007 IMO D. A = 21 B = 15 AuB = ??? Businesses did not report a net profit = 30 - AuB Statement I : AuB = A + B - AnB AnB = 12 so we can calculate AuB (which is 24) so it is sufficient Statment II : AuB = 24 therefore we can calculate the no of businesses which did not report a net profit P.S : Plz donot post answers.
