In each of the following questions, a group of three numbers/symbols is given in each option. Identify the group that does NOT follow the same pattern as the others.
A. A1@ : B2 : C3
B. D4% : E5^ : F6&
C. G7 : H8( : I9)
D. J10 : K11@ : L12@ (Correct answer)
Correct Answer
Option D — J10 : K11@ : L12@
Detailed Solution & Explanation
The correct answer is J10_ : K11@ : L12@.
Key Points
In A, B and C each triplet pairs its letter-number with a *unique* consecutive special symbol (e.g. A1@ : B2# : C3$).
In D, both K11 and L12 carry the same symbol @, so the 'one distinct symbol per element' rule is violated.
The letters and numbers are a decoy that all march in order; the real rule lives in the symbols, so compare those across the triplet.
