Two statements are given followed by two conclusions numbered I and II. Assuming the statements to be true, even if they seem to be at variance with commonly known facts, decide which of the conclusions logically follow(s) from the statements.
Statements:
Some vehicles are helicopters.
All helicopters are cars.
Conclusions:
I. All vehicles are cars.
II. Some vehicles are cars.
Neither conclusion I nor II follows
Only conclusion I follows
Either conclusion I or II follows
Only conclusion II follows
Correct answer
Only conclusion II follows
Why this answer is correct
Statements:
Some vehicles are helicopters.
All helicopters are cars.
The least possible Venn diagram for the given statement is:
Conclusion:
I. All vehicles are cars - False (Because, Some vehicles are cars, so All vehicles are cars is possible only).
II. Some vehicles are cars - True (Because, Some vehicles are helicopters and All helicopters are Cars so Some Vehicles are Cars is true).
So, Only conclusion II follows.
