Question
Three statements are given followed by three
conclusions numbered I, II & 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: All balls are metals Some metals are guns All guns are wood Conclusions: I. All balls are guns Il. All metals are wood IlI. Some guns are metalsSolution
The possible Venn diagram is: 
Conclusions: All balls are guns → False (As, no definite relation is given between balls and guns, so it can be a possibility only) All metals are wood → False (Because, only some part of metals is wood, so, all metals are wood can be a possibility only) Some guns are metals → True (Because, some metals are guns also implies some guns are metals) So, only conclusion III follows. Hence, the correct answer is (D).
