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 cards are plastics.
Some plastics are woods.
Conclusions:
I. Some cards are woods.
II. No card is a wood.
Show answer & explanation
Correct answer: D
Explanation
The correct answer is option 4 i.e. Either conclusion I or II follows.
The possible Venn diagram is as follows:
Conclusions:
I. Some cards are woods → Does not follow → As, all cards are plastic and some some plastic are woods. So, some cards are woods is possible but not definitely followed.
II. No card is a wood → Does not follow → As, all cards are plastic and some some plastic are woods. So, no card is a wood is possible but not definitely followed.
There is a complimentary pair so Either conclusion I or II follows.
Hence, the correct answer is "Either conclusion I or II follows".
