Quick Concept Summary
Alphabet-test questions are built on one idea: every letter has a fixed position number (A=1 … Z=26). Once you can convert letters to numbers and back instantly, every question type — reverse order, gaps, midpoints, series — becomes simple arithmetic. Speed comes from memorising the EJOTY markers, not from counting A, B, C every time.
The EJOTY Memory Anchors
| Letter | E | J | O | T | Y |
|---|---|---|---|---|---|
| Position | 5 | 10 | 15 | 20 | 25 |
Jump to the nearest anchor and count a step or two. Example: find M → nearest is O(15), count back two → M = 13.
Key Rules
- Position from left: A=1, B=2, …, Z=26
- Reverse position: 27 − normal position (so the nth letter from the right = (27 − n)th from the left)
- Letters between two letters: |difference of positions| − 1
- Midpoint letter: (position₁ + position₂) ÷ 2
Question Types
Type 1 — Letter Position
"Which letter is 18th from the left?" → R.
Type 2 — Reverse / From the Right
"Which letter is 5th from the right?" → 27 − 5 = 22 → V.
Type 3 — Nth from Left = Mth from Right
"Which letter is 7th from the left and also which from the right?" → 27 − 7 = 20th from the right.
Type 4 — Gap Counting
| "How many letters are between F and N?" → | 14 − 6 | − 1 = 7. |
|---|
Type 5 — Word from Position Clues
Form a word by picking letters at given positions of the alphabet.
Worked Examples
Example 1: Find the 15th letter from the right. 27 − 15 = 12 → L.
Example 2: Which letter is exactly midway between D and P? D=4, P=16 → (4+16)/2 = 10 → J.
Example 3: How many letters lie between the 8th letter from the left and the 6th from the right? 8th from left = H(8); 6th from right = 27−6 = 21 → U. Letters between = 21 − 8 − 1 = 12.
Example 4: If the alphabet is written in reverse, which letter is 9th? 9th from the right = 27 − 9 = 18 → R.
Common Mistakes
- Counting from Z instead of using 27 − n for reverse positions.
- Forgetting the "− 1" when counting letters between two letters.
- Miscounting the middle when the position sum is odd (then there is no single middle letter).
Exam Tips
- Memorise EJOTY (5-10-15-20-25) — it cuts counting time in half.
- For "nth from right" always use 27 − n.
- These are 10–15 second questions; do not draw the whole alphabet unless the question mixes several conditions.
