According to the given information,

Statement: U & T & B % R & V & W $ Z $ A

On converting: U ≤ T ≤ B = R ≤ V ≤ W > Z > A

Conclusions:

I. U & V → U ≤ V → True (as U ≤ T ≤ B = R ≤ V i.e. U ≤ V is definitely true)

II. A $ W → A > W → False (W > Z > A → W > A)

III. R @ Z → R < Z → False (No relation between them)

According to the given information,

Statement: E @ F % G & H % I @ K & J

On converting: E < F = G ≤ H = I < K ≤ J

Conclusions:

I. G @ I → G < I → False (G ≤ H = I  → G ≤ I)

II. H # E → H ≥ E → False (E < F = G ≤ H →  E < H)

III. F $ K → F > K → False (F = G ≤ H = I < K  → F < K)

Statement: U & F % G & H % K # J

On converting: U ≤ F = G ≤ H = K ≥ J

Conclusions:

I. G $ J → G > J → False (No relation between them)

II. G % K → G = K → False (G ≤ H = K → G ≤ K)

III. F $ H → F > H → False (F = G ≤ H→ F ≤ H)

According to the given information,

Statement: L $ M % O # N @ R % J

On converting: L > M = O ≥ N < R = J

Conclusions:

II. N @ L → N < L → True (as L > M = O ≥ N i.e.N < L is definitely true)

III.J $ N → J > N → True (as N < R = J i.e. J > N is definitely true)

1. A is the grandmother of D who works in the Indian Overseas Bank.

2. A has only one male child who is not married, which means A has at least one daughter who is the mother of D.

3. The one who works in SBI is the sister-in-law of A. (there will be two cases, Case -1 is – the one who works in SBI is the sister of the husband of A., and in case 2, she can be the wife of the brother of A. But here there is no data about the brother of A further. So, case 2 is not considered, and also we have already mentioned that no single parent is there in the family.).

4. C has two children and one of them is E.

C cannot work in SBI or be a Husband of the one who works in SBI because this will exceed the limit of seven members in the family.

Since there is no single parent, so D will have a mother and father who will complete the family tree.

So, after performing the above steps we have one option for C to be the husband of A.

5. A and C work in UCO and HDFC banks respectively.

6. B belongs to the first generation. So, B will be the sister-in-law of A as there is no other place left for her.

7. G works in an Indian bank and is not the child of A, so here we can see that only one place is left for the father of D as we have already mentioned that no single parent is there in the family.

Now we can complete the family of seven members.

8. The one who works in Canara bank is the brother of the one who works in PNB, who is not F.

Now only two places are left so we can infer that since F does not work in PNB so he will work in Canara bank and will be the brother of E.

9. Males are more in number than females in the family. So, the gender of D will be male.

So, D works in an Indian Overseas bank.

Now only two places are left so we can infer that since F does not work in PNB so he will work in Canara bank and will be the brother of E.

9. Males are more in number than females in the family. So, the gender of D will be male.

The one who works in UCO bank is A and she is the mother-in-law of the one who works in Indian bank who is D.

1. A is the grandmother of D who works in the Indian Overseas Bank.

2. A has only one male child who is not married, which means A has at least one daughter who is the mother of D.

3. The one who works in SBI is the sister-in-law of A.

9. Males are more in number than females in the family. So, the gender of D will be male.

So, we conclude that E works in PNB bank.

2nd, 3rd, and 8th letter from the first word is: L, O, and A

1st, 3rd, and 5th letters from the second word is: G, N, and O

Combining and un-jumbling the letters we get: LAGOON

Vowel → Next vowel → Alphabetic order

Vowels are A, E, I, O, and U

The word “AMERICAN” after changing the vowel to the next vowel is “EMIROCEN”

After alphabetic order rearrangement “EMIROCEN” → “CEEIMNOR”

Letters remained unchanged after rearrangement,

So, E is unchanged.

'Inefficient managers can or cannot work with average workers' is not the context of the statement. So option (B) is incorrect.

The statement does not specify the reason why smart workers prefer working alone, so option (C) is incorrect.

Option (D) and option (E) cannot be determined from this statement, so they are not implicit.

Step 1: Place all the symbols which are preceded and followed by a letter, between 3W.

Symbols immediately preceded and followed by a letter: only % (N % O)

Therefore, we will shift % in between 3 and W as follows:

L 5 C # 1 @ J 2 B N O Q &3 % W K P $ 4 X

Step 2: After completing step 1, shift all the numbers between J and 2 that are immediately preceded by a symbol and immediately followed by a letter.

Numbers immediately preceded by a symbol and immediately followed by a letter:

L 5 C # 1 @ J 2 B N O Q & 3 % W K P $ 4 X: Only 4 ($ 4 X)

Therefore, we will shift 4 in between J and 2 as follows:

L 5 C # 1 @ J 4 2 B N O Q & 3 % W K P $ X

Here we see first option that is (@, B, &), it clearly gives us a pattern that second element is first element + 4. Same for third element is second element + 4.

Similarly, all options except (J B 3) follow the above pattern.Hence J B 3 is the odd one out.
