Three statements are given, followed by three conclusions numbered I, II, and III. 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 rains are cyclones.
Some cyclones are draughts.
No draught is a thunder.
Conclusions:
I. Some cyclones are rains.
II. No thunder is a cyclone.
III. No draught is a rain.
Show answer & explanation
Correct answer: A
Explanation
The correct answer is option 1 i.e. Only conclusion I follows.
The least possible Venn Diagram for the given statements is drawn below:
Conclusions:
I. Some cyclones are rains → True (As some rains are cyclones, so the reverse of some cyclones are rains is also true.)
II. No thunder is a cyclone → False (It is possible, but no definite conclusion can be drawn.)
III. No draught is a rain → False (It is possible, but no definite conclusion can be drawn).
