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:
No card is a parcel.
All cards are envelopes.
Some envelopes are bags.
Conclusions:
I. All envelopes can never be parcels.
II. No card is a bag.
III. All bags are cards
Show answer & explanation
Correct answer: E
Explanation
The correct answer is option 5 i.e. Only 1 follows.
The least possible Venn diagram is as follows:
Conclusions:
I. All envelopes can never be parcels: follow (as some envelops that are cards can never be parcel so, all envelops can never be parcel)
II. No card is a bag: Doesn't follow (It is possible but not definite)
III. All bags are cards: Doesn't follow (It is possible but not definite)
