Directions : In question, some statements are given, followed by two conclusions I and II. 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, follow from the given statements. Indicate your answer.
Statements :
A few wheels are warm.
Only wheels are wools.
Conclusions :
I. Some wheels are wools.
II. All wools are warm.
Options
- AIf only conclusion I follows.
- BIf only conclusion II follows.
- CIf both conclusion I and II follow.
- DIf neither conclusion I nor II follows.
Correct answer
A. If only conclusion I follows.
Step-by-step solution
Venn Diagram Method:
Analytical Method:
Statements :
A few wheels are warm.
Only wheels are wools.
Conclusions :
I. Some wheels are wools.
II. All wools are warm.
Checking C1: Some wheels are wools.
Only wheels are wools (All wools are wheels but wools can't be others) → conversion → Some wheels are wools. Hence, conclusion I follows.
Checking C2: All wools are warm.
As per the explanation above, we know that 'Wools can't be others'. Thus C2 doesn't follow.
Hence, option A is correct.
