Therefore, the correct answer is "Option 4".
Question 2
5 / -1

In the following question below are given some statements followed by some conclusions based on those statements. Taking the given statements to be true even if they seem to be at variance from commonly known facts. Read all the conclusions and then decide which of the given conclusion logically follows the given statements.
Statements:
I. All K are G.
II. Some G are H.
Conclusions:
I. Some H are K.
II. No K is H.

A
Both conclusion I and II follows

B
Only conclusion II follows

C
Either I or II conclusion follows.

D
Only conclusion I follows

Solution

The least possible Venn diagram is:
Conclusions:
I. Some H are K. → False (As, there is no definite relation between H and K. Hence, false)
II. No K is H. → False (As, there is no definite relation between H and K. Hence, false)
Additional Information
Complementary pair
1) When both the elements of conclusions are the same.
2) When both the conclusions are false individually.
There are only two different types of complementary pairs, which satisfy the condition of either or.
1) All - Some not
2) No - Some
Here, some + no forms a complementary pair.
Hence, either I or II follows.
Question 3
5 / -1

Which one of the following figures represents the relationship among Amritsar, Punjab, and Vadodara?

A

B

C

D

Solution

The logic followed is:
Amritsar is in Punjab and Vadodara is in Gujarat.
This means Vadodara is represented separately from Amritsar and Punjab.
The figure that can represent the relationship among Amritsar, Punjab, and Vadodara is a figure (3).
Hence, the correct answer is "Option 3".
Question 4
5 / -1

In this question, two statements have been given followed by two conclusions numbered I and II. Assuming that all information in the statement is true, analyse the two conclusions together and determine whether any of them logically and definitely follow(s) from the information given in the statement.
Statement:
All bats are balls.
All balls are wickets.
Conclusions:
I. Some bats are not wickets.
II. Some wickets are bats.

A
Both I and II follows

B
Only II follows

C
Neither I nor II follows

D
Only I follows

Solution

The least possible Venn diagram for the given statements is as below:
Conclusions:
1. Some bats are not wickets → False (As all bats are balls and all balls are wickets, thus all the bats will also be wickets is correct so it is not possible some bats are not wickets.)
2. Some wickets are bats → True (As all bats are balls and all balls are wickets, thus all the bats will also be wickets and some wickets are bats is a definite conclusion).
Hence, the correct answer is "Only II follows".

Question 5
5 / -1

In a class of 68 students, 34 students participated only in Debate and 8 students participated in both Quiz and Debate. If every student of the class has participated in at least one of these two competitions, how many students participated in Quiz?

A
22

B
30

C
34

D
26
Solution
Given Total number of students = 68
Number of students participated only in Debate = 34
Number of students participated in both Quiz and Debate = 8
If every student of the class has participated in at least one of these two competitions
Number of students participated only in Quiz = Total number of students - (Number of students participated only in Debate + Number of students participated in both Debate and Quiz)
- Number of students participated only in Quiz = 68 - (34 + 8)
- Number of students participated only in Quiz = 68 - 42 = 26
Number of students participated in quiz = Number of students participated only in Quiz + Number of students participated in both Quiz and Debate
∴ Number of students participated in quiz = 26 + 8 = 34
Hence, the correct answer is "34".
Question 6
5 / -1

Select the option that is true about the Statements and Conclusions given:
Statements:
Some crayons are pens
Some pens are jeeps
Conclusions:
I. All crayons are jeeps
II. Some crayons are jeeps

A
only conclusion II follows

B
only conclusion I follows

C
neither conclusion I nor conclusion II follows

D
both conclusion I and II follows

Solution

The least possible Venn diagram for the given statements is as follows:
I. All crayons are jeeps → False (As there is no relation between crayon and jeep)
II. Some crayons are jeeps → False (As there is no relation between crayon and jeep)
Hence, neither conclusion I nor II follows.

II. All grass are horses.

A
If neither conclusion I nor II follows

B
If only conclusion I follows

C
If either conclusion I or II follows

D
If only conclusion II follows

Solution

The least possible Venn diagram for the given statements is as below,
Conclusions:
1. All horses are grass → True (It is clear that all the horses are buffaloes and all the buffaloes are grass so all horses are grass is a definite conclusion).
2. All grass are horses → False (It is possible but not definite).
Hence, the correct answer is "If only conclusion I follows".
Additional Information
Suppose for an Example: All A are B.
If we go from In to Out means from A to B then cases with All and some will be true like All A are B and Some A are B.
But if we go Out to In then only cases with Some will be true and All will be can't say like Some B are A will be true but All B are A will be can't say.
