Directions: In each question three statements followed by two conclusions numbered I and II have been given. You have to take the given statement to be true even if they seem to be at variance with commonly known facts and then decide which of the given conclusions logically follows from the given statements. Give answer.
Statements :
All frocks are pants.
100% shorts are frocks.
Some jackets are pants.
Conclusions :
I. All pants are shorts.
II. All shorts being jackets is a possibility.
Options
- AIf only conclusion I follows.
- BIf only conclusion II follows.
- CIf neither conclusion I nor II follows.
- DIf both conclusion I and II follows.
Correct answer
B. If only conclusion II follows.
Step-by-step solution
Statements:
All frocks are pants.
100% shorts are frocks.
Some jackets are pants.
Conclusions:
I. All pants are shorts.
II. All shorts being jackets is a possibility.
Checking C1: All pants are shorts.
Using S2 and S1, we get
'100% shorts are frocks' or 'All shorts are frocks' +& 'All frocks are pants' = All shorts are pants. Clearly, C1 doesn't follow.&
Checking C2:& All shorts being jackets is a possibility.
As there is no negative statement, possibility between 'shorts' and 'jackets' does exist. C2, hence, follows.
Evidently, option B is the correct answer.
All frocks are pants.
100% shorts are frocks.
Some jackets are pants.
Conclusions:
I. All pants are shorts.
II. All shorts being jackets is a possibility.
Checking C1: All pants are shorts.
Using S2 and S1, we get
'100% shorts are frocks' or 'All shorts are frocks' +& 'All frocks are pants' = All shorts are pants. Clearly, C1 doesn't follow.&
Checking C2:& All shorts being jackets is a possibility.
As there is no negative statement, possibility between 'shorts' and 'jackets' does exist. C2, hence, follows.
Evidently, option B is the correct answer.
