Question
In the following question, three statements are given
each followed by four conclusions I, II, III and IV. You have to consider the statements to be true even if they seem to be at variance from commonly known facts. You have to decide which of the given conclusions, if any, follows from the given statements. Statements : (i) No Switch is Broad. (ii) No Broad is Tape. (iii) All Tapes are plug. Conclusion : (i) No tape is switch. (ii) No plug is a board. (iii) No plug is a switch. (iv) All plug are Tapes.Solution
No switch is broad (E) + No broad is tape (E) ⇒ No conclusion. Hence conclusion I and II do not follow. No broad is tape (E) + All tapes are plugs (A) ⇒ Some plugs are not broads (O)*). Hence conclusion II does not follow. All tapes are plugs (A) ⇒ Conversion ⇒ Some plugs are tapes (I). Hence conclusion IV does not follow. Alternate Method:
