Instructions

In each of the question below are given three statements followed by three conclusions numbered I, II III. You have to take the given statements to be true even if they seem to be at variance from commonly known facts Read all the conclusions and then decide which of the given conclusions logically follows from three given statements disregarding commonly known facts. Then decide which of the answer 1),2),3),4) and 5) is the correct answer and indicate it on the answersheet.

Question 13

# Statements:All sweets are fruits No fruits is pencil Some pencils are glassesConclusions:I.Some glasses are sweets II.Some pencils are sweets III.No glass is sweet.

Solution

We use elimination to find an exception to the generality of the conclusions. Thus we prove they are not implied. The diagram above satisfies all the statements but contradicts the conclusion II. Since we found an exception, the conclusion is not true in "every" case. Thus it is not implied.

Irrespective of the diagram, conclusions I and III are universally complimentary ie. one of the two always has to be implied but both can't be true at the same time. Hence we use "either" and "or".
