Constable GD 2026 — General Intelligence & Reasoning: Coding-Decoding Concept Guide + 10 MCQs
Master Coding-Decoding for Constable GD 2026. This guide covers theory, shortcuts, and 10 practice MCQs.
Concept: Coding-Decoding
Coding-Decoding finds patterns that encode words. Common types: letter shifting (+1, +2, -1), number coding (A=1), reverse alphabet (A=26), letter reversal.
Steps
- Check shift for 2-3 letters
- Try number coding (A=1 to Z=26)
- Try reverse: 27-position
⚡ Shortcuts & Tricks
- Write A=1...Z=26 on rough paper
- Verify pattern on all letters
- Consider alternating shifts if simple doesn't work
