Given Series:

(Left) T J R M G K S M O X Z W Z D T B L N Z O L (Right)

Required pattern:

Vowel → Vowel → Consonant

Checking the series:

(Left) T J R M G K S M O X Z W Z D T B L N Z O L (Right)

There is no vowel which is immediately preceded by another vowel and immediately followed by a consonant.

Vowels satisfying the condition:

→ None

Therefore, there are 0 such vowels.

Hence, the correct answer is "Option 1".

Logic followed here is the comparison method of coding-decoding, where we identify common letters and their corresponding digits in the given word-code pairs.

For the given words:

FISH is coded as '2815'

SHIP is coded as '1352'

Therefore, the code for P is 3.

Hence, the correct answer is "Option 4".

Given:

KV 14 → MT 34:

GR 27 → IP 47:

Applying the same logic to CN 35:

Thus, CN 35 is related to EL 55.

Hence, the correct answer is 'Option 1'.

The logic followed here is:

Logic: Second Number = First Number + 8; Third Number = (Second Number × 4) − 2

For the first set (2, 10, 38)

⇒ 2 + 8 = 10

⇒ (10 × 4) − 2 = 40 − 2 = 38.

For the second set (4, 12, 46)

⇒ 4 + 8 = 12

⇒ (12 × 4) − 2 = 48 − 2 = 46.

Applying the same logic to the options, we find Option 1:

(7, 15, 58)

⇒ 7 + 8 = 15

⇒ (15 × 4) − 2 = 60 − 2 = 58.

Hence, the correct answer is 'Option 1'.

The logic followed here is

Logic: 1^st Letter of Cluster 1 − 2 = 1^st Letter of Cluster 2 and 2^nd Letter of Cluster 1 − 2 = 2^nd Letter of Cluster 2.

Option 1)  TW - RU,

Option 2)  JM - HK,

Option 3)  PS - NQ,

Option 4)  IK - FH,

This pair does not follow the −2 shift rule. Also, the difference between letters in the other clusters is 3 (T+3=W, J+3=M, P+3=S), while in this cluster it is 2 (I+2=K).

Therefore, the letter-cluster pair that is different from the others is IK - FH.

Hence, the correct answer is 'Option 4'.

The logic followed here is based on the English alphabetical order.

Logic: 1^st letter + 2 = 2^nd letter and 2^nd letter − 5 = 3^rd letter.

Option 1) LNI,

Option 2) NHY,

This letter-cluster does not follow the rule.

Option 3) OQL,

Option 4) GID,

Therefore, the letter-cluster that is different from the others is NHY.

Hence, the correct answer is 'Option 2'.

Signs Interchange:

Given Equation:

536 + 67 × 9 − 22 ÷ 283

After interchanging the signs as per the rules (+ with ÷ and − with ×), the equation becomes:

= 536 ÷ 67 − 9 × 22 + 283

= 8 - 9 × 22 + 283

= 8 - 198 + 283

= 291 - 198

= 93

Therefore, the value that will come in place of the question mark is 93.

Hence, the correct answer is "Option 4".

Operation Symbol Mapping:

Given Expression →

45 L 21 K 7 J 6 I 33 J 9 L 15 I 69 K 3 L 29 = ?

Substituting the mathematical signs for the letters:

= 45 − 21 ÷ 7 × 6 + 33 × 9 − 15 + 69 ÷ 3 − 29

= 45 - 3 × 6 + 33 × 9 - 15 + 23 - 29

= 45 - 18 + 297 - 15 + 23 - 29

= 365 - 62

= 303

Therefore, the value in place of the question mark is 303.

Hence, the correct answer is "Option 2".

According to the given information, let's arrange the seven people (C, D, E, F, J, K and L) in a row facing north.

Step 1: Only two people sit to the right of D. This means D is in the 5^th position from the left.

Step 2: L sits to the immediate left of D. So, L is in the 4^th position.

Step 3: Only two people sit between D and E. Since there are only two people to the right of D, E must be to the left of D at the 2^nd position.

Step 4: Only two people sit between J and L. L is at the 4^th position. Two people between J and L means J can be at the 1^st or 7^th position.

Step 5: F sits to the immediate right of K. This means K and F must be together in that order (KF).

Final Arrangement:

From the above arrangement, we can see that C sits at the third position from the left end of the row.

Hence, the correct answer is "Option 2".

1. Since all persons face the centre: Right = counter-clockwise and Left = clockwise. Fix I at position 1. B sits to the immediate right of I (counter-clockwise): I(1) → B(2). Also, B sits second to the left of C, which means C is two places counter-clockwise from B (or B is two places clockwise from C): C(4) → pos(3) → B(2).

2. G sits third to the left of I (clockwise direction): I(1) → pos(7) → pos(6) → G(5). So G is at position 5.

3. Two people sit between C and D when counted from the left of D (clockwise): D → skip 2 → C(4). If D is at position 7, skipping pos 6 and pos 5 leads to C at position 4. So D is at position 7.

4. H is not an immediate neighbor of G (pos 5). Neighbors of G are positions 4 and 6. Thus, H cannot be at pos 6. The only available seat for H is position 3. The remaining person E must be at position 6.

To find who sits third to the right of E, count three places in the counter-clockwise direction from E: E(6) → D(7) → I(1) → B(2). Therefore, B sits third to the right of E.

Hence, the correct answer is 'Option 2'.
