Question
Statements: Some banks are lockers.
Some lockers are stores. Some stores are panels. Conclusions: I. No bank is a store. II. Some stores are banks. III. Some lockers are not panels. In each question below are given three statements followed by three conclusions numbered I, II and III. You have to take the two given statements to be true even if they seem to be at variance with commonly known facts and then decide which of the given conclusions logically follows from the two given statements, disregarding commonly known facts.Solution
Some banks are lockers(I) + Some lockers are stores(I) ⇒ No conclusion. Hence, conclusion I and II will not follow but they will form a complementary pair. I + I = No conclusion. Hence, conclusion III will not follow. Alternate Method: Relevant Possible cases:
