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.

Question 148

# Statements: Some leaves are baskets. Some baskets are flowers. Some flowers are lakes.Conclusions:I.Some lakes are baskets. II.Some flowers are leaves. III.No lake is basket.

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 conclusions II and IV. Since we found an exception, the conclusions are not true in "every" case. Thus they are 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".
