Logical Reasoning (Reasoning) Mastery

Concept: No specific formula, relies on General Knowledge and finding relationships.

• Number Analogy Priority Order:
  Prime No. > Cube > Square > Multiplication > Addition
• Alphabet Analogy: Check gap between letters (+2, -3, etc).

• Position Numbers (EJOTY Rule): E=5, J=10, O=15, T=20, Y=25
• CFILORUX (3x Table): C=3, F=6, I=9, L=12, O=15...
• Opposite Pairs (Sum = 27):
  A↔Z (Azad), B↔Y (Boy), C↔X (Crux), D↔W (Dew)
  L↔O (Love), M↔N (Man)
• Formula: Opposite Letter Position = 27 - Current Position

Pattern Check List:

1. Difference (अंतर)
2. Double Difference (अंतर का अंतर)
3. Squares/Cubes neighbors (n² ± 1 or n³ ± 1)
4. Prime Numbers

• Symbols:
  Male: [+] or Box (□)
  Female: [-] or Circle (○)
  Married Couple: Double line (=) or (⇔)
  Generation Gap: Vertical line (|)
  Sibling: Horizontal line (-)
• Key Terms:
  Paternal = Father’s side (Chacha, Bua)
  Maternal = Mother’s side (Mama, Mausi)
  Only son/daughter = इकलौता

• Main Directions: North (Up), South (Down), East (Right), West (Left)
• Angles:
  Right Turn = 90° Clockwise
  Left Turn = 90° Anti-clockwise
• Shadow Rules:
  • Morning (Sunrise): Shadow falls towards West.
  • Evening (Sunset): Shadow falls towards East.
  • 12 Noon: No shadow.
• Shortest Distance: Pythagoras Theorem (H² = P² + B²)

• Total Persons (T): If rank provided from both sides (Left & Right):
  T = (Left + Right) - 1
• Position from other end: (Total - Given Position) + 1
• Persons Between:
  • Simple Case (Total > L + R): Gap = Total - (L + R)
  • Overlapping Case (Total < L + R): Gap = (L + R) - Total - 2

• Method: Venn Diagram
• All A are B: A circle inside B circle.
• Some A are B: Circles intersect.
• No A is B: Circles are separate.
• Either-Or Condition:
  1. Both conclusions must be False (individually).
  2. Subject & Predicate must be same.
  3. One Positive (Some/All) + One Negative (No/Some Not).

Rule: If King (>) appears, King wins. If opposite signs (e.g., A > B < C) appear, then "No Relation".

• Mirror Image: Left ↔ Right changes. Top/Bottom remain same.
  Trick: Draw on paper and look from back against light.
• Water Image: Top ↔ Bottom changes. Left/Right remain same.
  Trick: Subtract time from 18:30 for clock problems.

Rule: Always unfold in Reverse Order. The unfolded part looks like a Mirror Image of the folded part.

• Standard Dice: Sum of opposite faces = 7 (1 opp 6, 2 opp 5, 3 opp 4).
• General Dice Rules:
  • Rule 1 (One Common): Rotate Clockwise from common number.
  • Rule 2 (Two Common): The remaining numbers are opposite to each other.
• Open Dice: Alternate boxes are opposite (Skip one box).

• Triangles in Triangle: If base Divided, number parts (1, 2, 3...) and add. Sum = n(n+1)/2.
• Triangles in Box: Count small triangles formed by diagonals and Double it (n × 2).
• Squares in Grid (n × n): 1² + 2² + ... + n²
• Squares in Grid (m × n): (m×n) + (m-1)(n-1) ... until 0.

• Angle between Hands: θ = | (11/2)M - 30H |
• Coincide (0°): 11 times in 12 hours.
• Opposite (180°): 11 times in 12 hours.
• Right Angle (90°): 22 times in 12 hours.

• Linear (row): Fix one person from a definite clue (“A sits at extreme left”). Mark left–right clearly. “Between” and “immediate left/right” are different—read twice.
• Circular: All facing centre → positions go clockwise. If some face in/out, mark arrows on your rough figure.
• Parallel rows: Two lines facing each other—use two horizontal lines and match “opposite A” clues.
• Time rule: If stuck 90 seconds, mark partial arrangement, attempt other questions, return later.

• Use a table (Person × Mon–Sun or Slot × Activity) when many “on which day / who performed” clues appear.
• Combine clues that fix the same variable first (e.g. “only one gap between X and Y”).
• Watch for either–or and if–then constraints—they often break the puzzle open.

Identify the pattern from the last step backward or compare Step I → II → III. Common patterns: word length, vowel count, alphabetical order, sum of digits, shifting positions in fixed cycles.

• Work one step at a time; do not guess the whole machine in one glance.
• If numbers and words mix, check whether each step applies to whole input or only one element.

• Statement (1) alone enough → A; (2) alone → B; both needed → C; either alone → D; neither → E (options vary by exam—read instruction line every time).
• Do not solve fully if one statement already gives a unique answer.

• Track rotation (90°, 180°), mirror, number of elements, shading pattern, and inner–outer swap.
• Eliminate options that break the pattern on the second or third figure—first figure alone can mislead.

For embedded images, trace the outline of the small figure mentally inside the large one. For completion, look for symmetry, closed boundaries, and consistent line density. Practice 10 questions daily—non-verbal improves fastest with volume.

1. Syllogism + Inequality — high frequency in banking.
2. Seating + puzzles — build stamina for long sets.
3. Direction, ranking, blood relation — quick marks if accurate.
4. Coding–decoding, analogy, series
5. Non-verbal (mirror, dice, figures) — SSC-heavy
6. Input–output / machine when targeting banking mains or high-level prelims
