Question

In the following question, select the odd letter/letters from the given alternatives.

  1. A. GJJL (Correct answer)
  2. B. EHHK
  3. C. ADDG
  4. D. VYYB

Correct Answer

Option A — GJJL

Detailed Solution & Explanation

The correct answer is GJJL.

Key Points

  • Examine the gaps within each group. In EHHK: E→H is +3, H→H is 0, H→K is +3.
  • ADDG: A→D is +3, D→D is 0, D→G is +3. The same +3, 0, +3 pattern.
  • VYYB: V→Y is +3, Y→Y is 0, Y→B is +3 (wrapping past Z). Pattern holds.
  • GJJL: G→J is +3, J→J is 0, but J→L is only +2, breaking the pattern.
  • GJJL is therefore the odd one out.

Additional Information

  • The method for letter-group questions is to convert each letter to its alphabet position and examine the internal gaps, rather than comparing the groups by eye.
  • Here three of the four groups follow +3, 0, +3, with the repeated middle letter being the giveaway that a zero gap is part of the pattern.
  • Reading the gaps in the same direction for every option matters; reversing the order for one group is what usually produces a wrong answer.
