6) Read the given statements and conclusions carefully. Decide which of the given conclusion/s follow based on the
statements.
Statements: P>Z, N<T, M>N, Z>M
Conclusions:
I. P<T
II. N<Z
A) Neither I nor II is true
B) Both I and II are true
C) Only II is true
D) Only I is true
View Answer
C) Only II is true
Explanation:Let’s break down the statements and then evaluate the conclusions.
Given Statements:
⇒1. P > Z
⇒2. N < T ⇒3. M > N
⇒4. Z > M
Let’s try to build a chain where possible:
From statements 3 and 4:
M > N and Z > M ⇒ So, Z > M > N
From this, we can infer: Z > N
Now, from statement 1: P > Z
So: P > Z > M > N
Also, from statement 2: N < T, which means T > N
But no direct connection is established between P and T, or a full comparison between P and T can’t be confirmed.
—
Evaluating Conclusions:
Conclusion I: P < T From above: We know P > Z > M > N and T > N, but we don’t know the relationship between P and T.
So, Conclusion I does not follow.
Conclusion II: N < Z We established: Z > M > N, which implies Z > N or N < Z
So, Conclusion II follows.

✅ Correct Answer: Only II is true

8) Rubi and Juhi are sisters. Krishna is Juhi’s father’s father. Reshma is the mother of Arvind. Arvind is the father of Rohit, who is the only brother of Rubi. How is Krishna related to Rohit?
A) Mother’s brother
B) Father’s father
C) Father
D) Mother’s father
View Answer
B) Father’s father
Explanation:Let’s break it down step-by-step:
—
Given:
⇒1. Rubi and Juhi are sisters.
⇒ Rubi and Juhi have the same parents.
⇒2. Krishna is Juhi’s father’s father.
⇒ Krishna is Juhi’s grandfather on her father’s side.
⇒ Since Rubi and Juhi are sisters, Krishna is also Rubi’s grandfather (father’s father).
⇒3. Reshma is the mother of Arvind.
⇒4. Arvind is the father of Rohit.
⇒5. Rohit is the only brother of Rubi.
⇒ So Rubi and Rohit are siblings.
⇒ Rubi’s father = Rohit’s father = Arvind
Thus:
Rohit’s father = Arvind
Arvind’s mother = Reshma
Rohit’s grandfather (father’s father) = Krishna
—
✅ So, Krishna is Rohit’s father’s father, i.e., paternal grandfather.
✅ Correct Answer: Father’s father.
9) Six people A, B, C, D, E and F are sitting around a circular table facing the centre. C sits second to the left of B. E is an immediate neighbour of B. F sits third to the left of E. D sits second to the left of A.Who sits to the immediate right of A?
A) E
B) B
C) C
D) F
View Answer
C) C
Explanation:All are facing the center →
Left = counter-clockwise, Right = clockwise
—
Step 1: Start with B (since multiple clues revolve around B)
C sits second to the left of B
→ Second left = 2 seats counter-clockwise
→ So:
If B is at Position 1 → C will be at Position 5
E is an immediate neighbor of B
→ E is either at Position 6 or 2
Let’s try E at Position 2
—
Step 2: Place F
F sits third to the left of E
From E (Position 2), third left = 3 seats counter-clockwise:
1st left = 1
2nd = 6
3rd = 5
Position 5 is already taken by C ⇒ ❌ Conflict
So, try E at Position 6 instead.
Now:
B = 1
E = 6
C = 5 (still valid — 2nd left of B)
From E at Position 6, third left =
1st = 5
2nd = 4
3rd = 3 → So F = 3
Now we have:
B = 1
E = 6
C = 5
F = 3
—
Step 3: Use D and A clue
D sits second to the left of A
Means A → count 2 seats counter-clockwise → reach D
Try placing A at Position 4:
1st left = 3 (F)
2nd = 2 → Place D at 2
Final arrangement:
| Position | Person |
| ——– | —— |
| 1 | B |
| 2 | D |
| 3 | F |
| 4 | A |
| 5 | C |
| 6 | E |
—
Final Step: Who sits to the immediate right of A?
A is at Position 4
Right = clockwise → Position 5 → C
—
✅ Correct Answer: C
