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.
Statement:
Some Sofas are Chair.
Some Chairs are Tables.
All Tables are Beds.
Conclusions:
(I) Some Sofas are Tables.
(II) Some Chairs are Beds.
(III) Some Beds are Sofas.
Show answer & explanation
Correct answer: D
Explanation
The correct answer is Option 4 i.e. Only Conclusion II follows.
The least possible Venn Diagram for the given statements is drawn below:
Conclusions:
I. Some Sofas are Tables → False (It is possible, but no definite conclusion can be drawn.)
II. Some Chairs are Beds → True(As some chairs are tables and all tables are beds, so, some chairs are beds is also true.)
III. Some Beds are Sofas → False (It is possible, but no definite conclusion can be drawn.)
Hence, Only Conclusion II follows.
