Question
Statements: All threads are wools. Some
wools are ropes. All ropes are chains. Conclusions: I. Some wools are chains. II. Some ropes are chains. III. Some ropes are not chains. In each of the questions below are given three 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 given statements disregarding commonly known facts.Solution
Some wools are ropes(I) + All ropes are chains(A) ⇒ Some wools are chains(I). Hence conclusion I follows. All ropes are chains(A) ⇒I.I ⇒ Some ropes are chains(I). Hence conclusion II follows but conclusion III does not follow. ALTERNATE METHOD:
