Learning Objective

Convert letters to positions (A=1 … Z=26) using the EJOTY anchors and crack any letter-jump series.

🎯 Learning Objective

Convert letters to positions (A=1 … Z=26) using the EJOTY anchors and crack any letter-jump series.

💡 Concept

  • Every letter has a fixed position: A=1, B=2 … M=13, N=14 … Z=26
  • EJOTY anchors: E=5, J=10, O=15, T=20, Y=25 — jump from the nearest anchor to find any position
  • Example: R = T − 2 = 20 − 2 = 18; L = O − 3 = 15 − 3 = 12
  • A letter series is a number series in disguise: convert, find the jump, convert back
  • After Z the series wraps around: Z + 2 = B
  • Reverse position of a letter = 27 − forward position (5th from the Z-side is V = 22)

🧮 Key Formulas

A=1, B=2 … Z=26

>

EJOTY: E=5, J=10, O=15, T=20, Y=25

>

Reverse position = 27 − forward position

✏️ Easy Example

Q. Find the next letter: A, C, E, G, ?

  1. Positions: 1, 3, 5, 7
  2. Jump is +2, so next position = 9
  3. 9 = I

Answer: I

🇮🇳 Real-Life Example

Cinema hall rows run A, B, C … If your ticket says row J, EJOTY tells you it is the 10th row — walk straight to it while others count on their fingers.

📝 Exam-Level Example

Q. Find the next term: B, E, H, K, N, ?

  1. Positions: 2, 5, 8, 11, 14
  2. Jump is +3, so next = 17
  3. 17 = Q

Answer: Q

📝 Exam-Level Example

Q. Find the next term: C, F, J, O, ?

  1. Positions: 3, 6, 10, 15
  2. Gaps: +3, +4, +5 — next gap +6
  3. 15 + 6 = 21 = U

Answer: U

🪄 Memory Trick

Never count from A. Jump from the nearest EJOTY anchor: need W? Y − 2 = 23. Need G? E + 2 = 7.

⚠️ Common Mistakes

  • ❌ Counting positions from A every time — slow and error-prone
  • ❌ Forgetting the wrap after Z (Y + 3 = B, not a number beyond 26)
  • ❌ Mixing forward positions with reverse positions in one series

🏆 Exam Tips

  • ✅ Write EJOTY on your rough sheet the moment the exam starts
  • ✅ Practice till any letter's position takes under 3 seconds

📌 Summary

  • A=1 … Z=26 — positions are everything
  • EJOTY: E=5, J=10, O=15, T=20, Y=25
  • Letter series = number series in disguise
  • Wrap after Z; reverse position = 27 − forward
