Question

There are Three statements given below that are 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 with commonly known facts. Read all the conclusions and then decide which of the given conclusion/s logically follows from the given statements, disregarding commonly known facts. Statements: All tigers are jungles. No jungle is bird. Some birds are rains. Conclusions: I. No rain is jungle. II. Some rains are jungles. III. No bird is tiger.

• A. Only I and II follow
• B. Only III follows
• C. Only either I or II follow, and III follows
• D. All follow
• E. None follows

Hint:

When conclusions are complementary (one says "some are", the other says "no is"), either one may follow, but not both.

Answer 1

The Correct Option is C

Step 1: Statements: - All tigers are jungles. - No jungle is bird. - Some birds are rains.
Step 2: Conclusion III: No bird is tiger. From "All tigers are jungles" and "No jungle is bird", we get that no tiger is bird. This is equivalent to no bird is tiger. So III follows.
Step 3: Conclusion I and II: No rain is jungle / Some rains are jungles. We have "Some birds are rains" and "No jungle is bird". This gives no direct relationship between rains and jungles. It is possible that some rains are jungles or no rain is jungle. So either I or II could be true, but not both. Therefore, only either I or II follows.
Step 4: Final Answer: Only either I or II follow, and III follows.
