Alphabet Series

Letter-position tricks — the EJOTY shortcut and opposite-letter rule that make alphabet questions nearly instant.

📖 ~4 min read 🧠 RRB NTPC / Group D — Reasoning

Memorise: E=5, J=10, O=15, T=20, Y=25. Any other letter's position can be found by counting a few steps from the nearest anchor.

Opposite letter position = 27 − (given letter's position). Example: opposite of D (4th) = 27−4 = 23rd = W

💡 Example: Position of "R" → Using EJOTY, O=15. R is 3 letters after O → 15+3 = 18th position.

⚠️ Always check whether a question wants position "from the beginning" (A=1) or "from the end" (Z=1) — reverse-position questions are a common trap.
