Three Statements are given followed by three
conclusions numbered I, II and III. Assuming the statements to be true, even if they seem to be at variance with commonly known facts, decide which of the conclusion logically follow[s] from the statements. Statements: Few Friends are Friendships. No Friendships are Loyal. All Loyal are Smart. Conclusion: I. Some Smart are not Friends. II. Some Friendships are Smart. III. Some Friends are not Loyal.Solution
Few Friends are Friendships (I) + No Friendships are Loyal (E) → Some Friends are not Loyal (O) + All Loyal are Smart (A) → No conclusion. Hence conclusion I does not follow but conclusion III follows. No Friendships are Loyal (E) + All Loyal are Smart (A) → Some Smart are not Friendships (O*). Hence conclusion II does not follow.
