Question
In the following question, select the odd letter/letters from the given alternatives.
- A. GJJL (Correct answer)
- B. EHHK
- C. ADDG
- 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.
