Two 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:
All drums are bells.
All whistles are bells.
Conclusions:
I. Some drums are whistles.
II. Some bells are drums.
III. Some bells are whistles.
Show answer & explanation
Correct answer: A
Explanation
The correct answer is option 1 i.e. Both conclusions II and III follow.
The least possible Venn Diagram for the given statements is drawn below:
Conclusions:
I. Some drums are whistles → False (It is possible, but no definite conclusion can be drawn.)
II. Some bells are drums → True (As all drums are bells, so, some bells are drums is also true.)
III. Some bells are whistles → True (As all whistles are bells, so, some bells are whistles is also true.)
Hence, Both conclusions II and III follow.
