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 beds.
III. Some taps are cots.
Show answer & explanation
Correct answer: C
Explanation
The correct answer is option 3 i.e. All conclusions 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 beds → True (As all beds are tables and all tables are taps, so, some taps are beds is also true.)
III. Some taps are cots → True (As all cots are tables, and all tables are taps, so, some taps are cots is also true.)
Hence, All conclusions follow.
