Master these 10 reasoning shortcuts to solve Coding-Decoding, Seating Arrangement, and Blood Relations 3x faster in SSC CGL/CHSL exams.
Always note: A=1, B=2, ... Z=26. For reverse coding, use Z=1, Y=2. Trick: If APPLE → BQQMF, each letter is shifted +1. Check the shift pattern first.
Draw a family tree instead of reading linearly. Put the reference person at the center Mark M/F for gender; use arrows for direction
Always start with the person about whom most clues are given. Build outwards.
If differences aren't constant, take differences again. 2, 5, 10, 17, 26 → Diff: 3,5,7,9 → Diff of diff: 2,2,2 ✓
Identify the relationship category: Part-Whole, Cause-Effect, Synonym, Worker-Tool. Book : Library :: Patient : Hospital (Place where kept/treated)
For 2-statement syllogisms, draw overlapping circles. The most common trap: "Some A are B" ≠ "Some B are A" is valid!
Always draw a compass. After each turn, mark the new direction. Never solve in your head.
Element = (Row code) + (Column code). Find both individually.
Position from top + Position from bottom = Total + 1 If Riya is 12th from top and 9th from bottom: Total students = 12 + 9 - 1 = 20
The entire series follows the same logic. Identify step 1's logic (ascending/descending, alternating shift) and apply repeatedly.
