No gold is a copper.                                                Some coppers are not silvers.                                                Only silvers are stones. Conclusions:                      I. All silvers may be stones.                                                II. All stones are silvers. In each of the questions below are given three statements followed by two conclusions numbered I and II. You have to take the given statements to be true even if they seem to be at variance with commonly known facts. Read both the conclusions and then decide which of given conclusions logically follows from the given  statements disregarding commonly known facts. Give answerSolution
Only silvers are stones. ⇒ Some silvers are stones (I) ⇒ Probable conclusion ⇒ All silvers may be stones (A). Hence, Conclusion I follows. Only silvers are stones ⇒ All stones are silvers (A). Hence, conclusion II follows.Â
