4. In each of the following questions, relationship between different elements is shown in the statements. The statements are followed by two Conclusions numbered I and II. Study the Conclusions based on the given statement and select the appropriate answer.

From the question (4-6)
Give answer (1) if both the Conclusion I and Conclusion II are true
Give answer (2) if neither Conclusion I nor Conclusion II is true
Give answer (3) if only Conclusion I is true.
Give answer (4) if only Conclusion II is true.
Give answer (5) if either Conclusion I or Conclusion II is true.
Statements
N ≥ T > R = M ≤ H;
F ≥ Q = M < L
Conclusions
I. L < N
II. F > H

Correct Answer: (2)
Solution:

N ≥ T > R = M ≤ L
F ≥ Q = M ≤ H
Conclusions
I. L ≤ N : Not True
II. F > H : Not True

5. Study the above information carefully and answer the questions.

Statements
H < N ≤ M = G ≥ K;
P ≥ M = I > J
Conclusions
I. K < J
II. P > H

Correct Answer: (4)
Solution:

K ≤ M = I > J
H < N ≤ M ≤ P
Conclusions
I. K < J : Not True
II. P > H : True

6. Study the above information carefully and answer the questions.

Statements
Q < P > O ≥ N > M;
C > O ≤ A = G
Conclusions
I. K < J
II. P > H

Correct Answer: (3)
Solution:

G ≥ O ≥ N > M
Q < P > O < C
Conclusions
I. M < G : True
II. C > Q : Not True

7. In each of the questions below, some statements are given followed by two Conclusions numbered I and II. You have to assume all the statements to be true even if they seem to be at variance from the commonly known facts and then decide which of the given two Conclusions logically follow(s) from the information given in the statements.

From the question (7-10)
Give answer (1) if either Conclusion I or Conclusion II follows.
Give answer (2) if both the Conclusion I and Conclusion II follow.
Give answer (3) if neither Conclusion I nor Conclusion II follows.
Give answer (4) if only Conclusion I follows.
Give answer (5) if only Conclusion II follows.
Statements
All M are S.
All P are S.
All R are S.
Conclusions
I. All M being P is a possibility.
II. At least some R are M.

Correct Answer: (2)
Solution:

(i) All M are S → Universal Affirmative (A-type).
(ii) Only a few (=Some) C are P → Particular Affirmative (I-type).
(iii) No F is C → Universal Negative (E-type).
(iv) Some F are not C → Particular Negative (O-type).
All the three statements are Universal Affirmative (A-type).
Not any two statements are aligned properly.
Therefore, no Conclusion follows from any of these two statements.

Venn diagrams of “All P are S”:

After combining the venn diagrams II and IV, we get:

Venn diagram VII supports the Conclusion I.
After combining the venn diagrams II and VI, we get:

Venn diagram VIII supports the Conclusion II.

8. Study the above information carefully and answer the questions.

Statements
No P is R.
Only a few C are P.
Only a few B are R.
Conclusions
I. All B can never be P.
II. Some R are definitely not C.

Correct Answer: (3)
Solution:

(i) All M are S → Universal Affirmative (A-type).
(ii) Only a few (=Some) C are P → Particular Affirmative (I-type).
(iii) No F is C → Universal Negative (E-type).
(iv) Some F are not C → Particular Negative (O-type).

I + E ⇒ O-type of Conclusion
“Some C are not R”.
Venn diagrams of “Some C are not R”:

Venn diagram II contradicts the Conclusion II.

E + I ⇒ O₁ - type of Conclusion
“Some B are not P”.
Venn diagrams of “Some B are not P”:

Venn diagrams IV, V and VI supports the Conclusion I.

9. Study the above information carefully and answer the questions.

Statements
No F is C.
Only a few F are T.
All P are C.
Conclusions
I. All T being C is a possibility.
II. Some P are F.

Correct Answer: (3)
Solution:

(i) All M are S → Universal Affirmative (A-type).
(ii) Only a few (=Some) C are P → Particular Affirmative (I-type).
(iii) No F is C → Universal Negative (E-type).
(iv) Some F are not C → Particular Negative (O-type).

I + E ⇒ O-type of Conclusion
“Some T are not C.”
This Conclusion contradicts the Conclusion I.

A + E ⇒ E-type of Conclusion
“No P is F”.
This Conclusion contradicts the Conclusion II.

10. Study the above information carefully and answer the questions.

Statements
Only a few M are U.
All P are M.
No T is U.
Conclusions
I. All U can never be P.
II. All T being M is a possibility.

Correct Answer: (5)
Solution:

(i) All M are S → Universal Affirmative (A-type).
(ii) Only a few (=Some) C are P → Particular Affirmative (I-type).
(iii) No F is C → Universal Negative (E-type).
(iv) Some F are not C → Particular Negative (O-type).

E + I ⇒ O₁-type of Conclusion
“Some M are not T”.
Venn diagrams of “Some M are not T”:


Venn diagram II supports the Conclusion II.
Venn diagrams of “Some M are U”:

Venn diagrams of “All P are M”:

After combining venn diagrams V and VIII, we get:

Venn diagram IX contradicts the Conclusion I.
