Question 1: In the question below some statements are given followed by two conclusions I and II. You have to take the given statements to be true even if they seem to be at variance with commonly known facts. Read all the conclusions and then decide which of the given conclusion definitely follows from the given statements, disregarding commonly known facts.
Statements:

Hence, option a.
Question 5: In the question below there are three statements followed by two conclusions I and II. You have to take the three given statements to be true even if they seem to be at variance from commonly known facts and then decide which of the given conclusions logically follows from the three statements disregarding commonly known facts.
Statements:
Only fact is valid
Only a few fact is known
Mostly known is sure
Conclusions:
I. Some known can be valid
II. All fact can be sure
A) Only conclusion I follows
B) Both the conclusions I and II follow
C) Neither conclusion I nor II follow
D) Only conclusion II follows
E) Either conclusion I or II follows
Solution:
Following figure can be formed from the statements:
Since only fact is valid is given which means all valid can only be a part of fact so, both the conclusions do not follow.
Neither conclusion I nor II follow.
Hence, option c.
Question 6: In the question below there are three statements followed by two conclusions I and II. You have to take the three given statements to be true even if they seem to be at variance from commonly known facts and then decide which of the given conclusions logically follows from the three statements disregarding commonly known facts.
Statements

Every cover is front
Some front is screen
Conclusions
I. All front is back is a possibility
II. Some cover is screen
A) Only conclusion I follows
B) Both the conclusions I and II follow
C) Neither conclusion I nor II follow
D) Only conclusion II follows
E) Either conclusion I or II follows
Solution:
Following figure can be drawn from the statements.
Since all back cannot be front but all front can be back so conclusion I follows. There is no direct relation between screen and cover so conclusion II doesn’t follow.
Only conclusion I follows.
Hence option a.

A) Only conclusion I follows
B) Both the conclusions I and II follow
C) Neither conclusion I nor II follow
D) Only conclusion II follows
E) Either conclusion I or II follows
Solution:
Following figures can be formed from the statements:
From the above figure it is clear all toast can be jam so, conclusion II does not follow.
Only conclusion I follows.
Hence, option a.
Question 8: In the question below there are three statements followed by two conclusions I and II. You have to take the three given statements to be true even if they seem to be at variance from commonly known facts and then decide which of the given conclusions logically follows from the three statements disregarding commonly known facts.
Statements
Mostly pile is dile
Only a few dile is cyle
All cyle is mile
Conclusions
I. All cyle is pile
II. Some mile being pile is not a possibility
A) Only conclusion I follows
B) Both the conclusions I and II follow
C) Neither conclusion I nor II follow
D) Only conclusion II follows
E) Either conclusion I or II follows
Solution:
Following figure can be formed from the statements
There is no direct relation between cyle and pile so conclusion I doesn’t follow. There is a possibility of some mile being pile, as shown in the figure so conclusion II doesn’t follow.
Neither conclusion I nor II follow.
Hence, option c.
Question 9: In the question below there are three statements followed by two conclusions I and II. You have to take the three given statements to be true even if they seem to be at variance from commonly known facts and then decide which of the given conclusions logically follows from the three statements disregarding commonly known facts.
