In this question, 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 conclusion(s) logically follows/follow from the statements.
Statements:
All ladders are chairs.
All chairs are tables.
No table is a stair.
Conclusions:
I. Some tables are ladders.
II. No chair is a stair.
III. Some ladders are stairs.
Show answer & explanation
Correct answer: C
Explanation
The correct answer is option 3 i.e. Both conclusions I and II follow.
Conclusions:
I. Some tables are ladders → Follows (Since all ladders are tables (by combining statements 1 and 2), it is correct to say that some tables are ladders.)
II. No chair is a stair → Follows (All chairs are tables that are not stairs. So, No chair is a stair is true.)
III. Some ladders are stairs → Does not follow (All Ladders are chairs which are tables and tables are not stairs. So, ladders are stairs is not possible.)
