Two statements are given, followed by two conclusions numbered I and II. 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 dustbins are plastics.
All geysers are plastics.
Conclusions:
I. Some geysers are dustbins.
II. No geyser is a dustbin.
Show answer & explanation
Correct answer: C
Explanation
The correct answer is option 3 i.e. Either conclusion I or II follows.
The least possible venn diagram is:
Conclusions:
I. Some geysers are dustbins. → Does not follow (As there is no direct relation between them)
II. No geyser is a dustbin. → Does not follow (As there is no direct relation between them)
Thus, both forms a complementary pair. So, either conclusion I or II follows.
