Question
Statements : Some pens are tables. No
table is a book. Some books are threads Some threads are boxes. Conclusions: I. Some pens are not books.      II. All pens are either boxes or books. III. All boxes are either threads or books. In each of the questions below are given four statements followed by three conclusions numbered I, II and III. You have to take the given statements to be true even if they seem to be at variance with commonly known facts. Read all the conclusions and then decide which of given conclusions logically follows from the givenstatements disregarding commonly known facts.Solution
Some pens are tables (I) + No tables is books (E) = Some pens are not books (O). Hence 1st follows.
