Problem 7E

Suppose that during the most recent fiscal year, the annual revenue of Acme Computer was 138 billion dollars and its net profit was 8 billion dollars, the annual revenue of Nadir Software was 87 billion dollars and its net profit was 5 billion dollars, and the annual revenue of Quixote Media was 111 billion dollars and its net profit was 13 billion dollars Determine the truth value of each of these pro positions for the most recent fiscal year.a) Quixote Media had the largest annual revenue.________________b) Nadir Software had the lowest net profit and Acme Computer had the largest annual revenue.________________c) Acme Computer had the largest net profit or Quixote Media had the largest net profit.________________d) If Quixote Media had the smallest net profit, then Acme Computer had the largest annual revenue.________________e) Nadir Software had the smallest net profit if and only if Acme Computer had the largest annual revenue.

Step-by-Step Solution:
Step 1 of 3

Solution:Step1Given that the annual revenue and net profit of Acme Computer, Nadir Software,Quixote Media during the most recent fiscal year.Step2We have to determine the truth value of each of these pro positions for the most recent fiscal year.Step3We haveDuring the most recent fiscal yearAnnual Revenue (In Billion Dollars)Net profit (In Billion Dollars)Acme computer1388Nadir software875Quixote Media11113Step4a) Quixote Media had the largest annual revenue.The given statement is false.The truth value of these pro positions for the most recent fiscal year is 111 billion Dollar.Step5b) Nadir Software had the lowest net profit and Acme Computer had the largest annual revenue.The given statement is true.Because Nadir Software had the lowest net profit is 5 Billion Dollars and Acme Computer had the largest annual revenue is 138 billion dollars.Step6c) Acme Computer had the largest net profit or Quixote Media had the largest net profit.From the given data Acme Computer net profit - 8 billion dollars Quixote Media net profit - 13 billion dollarsSo, Quixote Media having the largest net profit.Step7d) If Quixote Media had the smallest net profit, then Acme Computer had the largest annual revenue.The given statement is true.Because then Acme Computer had the largest annual revenue.Step8e) Only if Acme Computer had the largest annual revenue if Nadir Software had the smallest net profit.The given statement is true.Because Nadir Software net profit - 5 billion dollar and Acme Computer annual revenue- 138 billion dollar.
