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:
Some cribs are pants.
No crib is a tap.
All pants are shells.
Conclusions:
I. All shells being cribs is a possibility.
II. At least some taps are not cribs.
III. Some pants are not taps.
Show answer & explanation
Correct answer: D
Explanation
The correct answer is option 4, i.e., all conclusions I, II, and III follow.
Conclusions:
I. All shells being cribs is a possibility → Follows (Some Cribs are pants, which are all shells. Some parts of shells are already in cribs. So, all shells may be cribs, it's possible.)
II. At least some taps are not cribs → Follows (According to the statement, no crib is a tap.)
III. Some pants are not taps → Follows ( No crib is a tap, and some cribs are pants. So, definitely that part of pants which is in the crib is not in tap)
