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:
All beds are tables.
All cots are tables.
All tables are taps.
Conclusions:
I. All cots are taps.
II. Some taps are tables.
III. Some beds are cots.
Show answer & explanation
Correct answer: C
Explanation
The correct answer is Option 3 i.e. Only conclusions I and II follow.
The least possible Venn Diagram for the given statements is drawn below:
Conclusions:
I. All cots are taps → True (As all cots are tables, and all tables are taps, so, all cots are taps is also true.)
II. Some taps are tables → True (As all tables are taps, so, some taps are tables is also true.)
III. Some beds are cots → False (It is possible, but no definite conclusion can be drawn.)
Hence, Only conclusions I and II follow.
