Question
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 conclusions logically follow(s) from the statements. Statements: Some chapters are topics. All topics are paragraphs. Some paragraphs are summary. Conclusions: I. Some chapters are paragraphs. II. Some paragraphs are topics. III. Some topics are chapters.Solution
Some chapters are topics (I) + All topics are paragraphs (A) β Some chapters are paragraphs (I). Hence conclusion I follows. All topics are paragraphs (A) β Conversion β Some paragraphs are topics (I). Hence conclusion II follows. Some chapters are topics (I) β Conversion β Some topics are chapters (I). Hence conclusion III follows.
