Reasoning PYQs

Given Information:

1. No one sits to the right of D.

2. Only three people sit between D and F.

3. Only two people sit between F and E.

4. X sits third to the left of V.

5. W sits to the immediate right of V.

U is at position 2 and E is at position 6.

People between them:

F, V, W → 3 people

Therefore, 3 people sit between U and E.

Hence, the correct answer is "Option 1".

Shortcut Trick

The differences between consecutive terms are 36, 30, 24, and 18.

The differences are decreasing by 6 in each step (Multiples of 6 in descending order).

Next difference = 18 − 6 = 12.

Next number = 129 + 12 = 141.

∴ The correct answer is 141.

Alternate Method

Given: 21, 57, 87, 111, 129, ?

21

+36
→

57

+30
→

87

+24
→

111

+18
→

129

+12
→

141

The series follows a pattern of decreasing differences based on multiples of 6.

⇒ 57 − 21 = 36 (6 × 6)

⇒ 87 − 57 = 30 (6 × 5)

⇒ 111 − 87 = 24 (6 × 4)

⇒ 129 − 111 = 18 (6 × 3)

⇒ Following the sequence, the next difference must be 12 (6 × 2)

⇒ ? = 129 + 12

⇒ ? = 141

∴ The correct answer is 141.

Additional Information

Difference-based Series

This is a series where the logic resides in the first layer of subtraction. If the first layer is inconsistent, always check for a "double difference" (the difference between the differences).

Descending Multiples Pattern

Patterns often involve adding multiples of a specific constant (like 6 in this case) in either ascending or descending order. To identify this, divide the extracted differences by the smallest common factor.

Arithmetic Progression in Differences

When the differences (36, 30, 24, 18, 12) have a constant gap (−6), they are said to be in an Arithmetic Progression.

Logic followed here is: (1^st letter - 3 = 2^nd letter) and (2^nd letter - 6 = 3^rd letter).

1. DAU →

2) FCV →

3. TQK →

 

4. ROI →

Therefore, the letter-cluster 'FCV' is the odd one out because the difference between the second and third letter is 7 instead of 6.

Hence, the correct answer is "Option 2".

Given Information:

1. G is kept immediately above B.

2. D is kept immediately above F.

3. Only E is kept above A.

4. Only two boxes are kept above G.

5. D is not kept at third position from the bottom.

Final Arrangement:

 

D is at position 6 from the top.

Boxes above D: E, A, G, B, C → 5 boxes

Therefore, 5 boxes are kept above D.

Hence, the correct answer is "Option 2".

Given Equation:

(84 × 12) ÷ 4 − (72 × 9) ÷ 3 + 15 = ?

Condition:

‘+’ and ‘−’ are interchanged.

‘×’ and ‘÷’ are interchanged.

Replacing the operators

 

New equation becomes:

= (84 ÷ 12) × 4 + (72 ÷ 9) × 3 − 15

= 7 × 4 + 8 × 3 − 15

= 28 + 24 − 15

= 52 − 15

= 37

Therefore, the value of the expression is 37.

Hence, the correct answer is "Option 2".

Logic Followed:

We need to find even numbers that are:

Immediately preceded by an odd number and immediately followed by an odd number.

Required Pattern:

Odd Number → Even Number → Odd Number

Checking the Series:

(Left) 6 1 7 8 5 5 6 1 1 4 2 9 2 3 8 9 5 9 1 5 3 7 8 8 3 2 5 (Right)

Therefore, there are 5 such even numbers.

Hence, the correct answer is "Option 4".

Given:

 

Given Equation:

9 B 4 D 18 A 9 C 12 = ?

Replace the letters with symbols

= 9 × 4 - 18 ÷ 9 + 12

= 9 × 4 - 2 + 12

= 36 - 2 + 12

= 48 - 2

= 46

Therefore, the value of the expression is 46.

Hence, the correct answer is "Option 4".

Given Codes:

 

Given Expression:

K × N − L # E % C: K is the wife of N. N is the brother of L. L is the daughter of E. E is the father of C.

Family Chain:

So, E is Husband’s father of K.

Hence, the correct answer is "Option 4".

Given:

Total people in the row = 40

Rina is 8^th from the right end.

Tara sits 6^th to the left of Rina.

Step 1: Find Rina’s position from the left

Position from left = Total people − Position from right + 1

= 40 − 8 + 1

= 33^rd from the left

Step 2: Find Tara’s position

Tara is 6 places to the left of Rina.

= 33 − 6

= 27^th from the left

Therefore, Tara’s position from the left end is 27^th.

Hence, the correct answer is "Option 4".

Step-by-step Position Tracking:

 

Net Movement:

North–South movement cancels out:

Some ships are tables.

All pots are tables.

Venn Diagram Logic:

Conclusions:

(I) Some pots are rocks → Does not follows (Because there is no definite relation between pots and rocks.)

(II) Some pots are ships → Does not follows (Because there is no definite relation between pots and ships.)

Therefore, neither Conclusion I nor II follows.
