Select the triad which follows the same pattern as that followed by the two triads given below. Both triads follow the same pattern. TODE - EOTD - ODTEFAST - TAFS - ASFT
BACK - KABC - ACBK
GREW - GERW - WERG
NEST - TENS - SENT
PACK - APCK - KACP
BACK - KABC - ACBK
Observe the positional shift of letters: the 1st and 2nd letters swap positions, while the 3rd and 4th remain in their original relative positions, then the 1st and 3rd letters swap. Actually, look closely: Word 1 тЖТ Word 2 swaps the first two letters. Word 2 тЖТ Word 3 swaps the first and third letters.

Analyze the pattern in triads
In TODE-EOTD-ODTE: (1) TODE to EOTD: Swap letters at pos 1 and 2 (T,O тЖТ O,T). Wait, let's re-evaluate: TODE тЖТ EOTD is (O, T, D, E) shifted? No. TODE (T-O-D-E) тЖТ EOTD. Positions: 1234 тЖТ 2134 (OTDE) then shift. Actually, the pattern is: Start: 1234. Second: 2134 (Swap 1-2). Third: 3124 (Swap 1-3). Check with FAST: 1234 (F-A-S-T) тЖТ 2134 (A-F-S-T) тЖТ 3124 (S-F-A-T). My previous observation was slightly off. Let's look at the given triads: TODE-EOTD-ODTE. T-O-D-E (1-2-3-4). EOTD (4-2-3-1?) No. Let's look at: TODE (1234) тЖТ EOTD (2134? No, E is 4). It is E-O-T-D. This is 4-2-1-3. Then O-D-T-E. This is 2-3-1-4.
Correct logic identification
TODE (1-2-3-4) тЖТ EOTD (4-2-1-3) тЖТ ODTE (2-3-1-4). FAST (1-2-3-4) тЖТ TAFS (4-2-1-3) тЖТ ASFT (2-3-1-4). Let's test BACK (1-2-3-4) with this: BACK тЖТ KABC (4-2-1-3) тЖТ ACBK (2-3-1-4). This matches the provided Option A exactly.
B: GREW-GERW-WERG does not follow the 4-2-1-3 then 2-3-1-4 sequence. C: NEST-TENS-SENT does not follow the sequence. D: PACK-APCK-KACP does not follow the sequence.
A is correct because the sequence follows the specific permutation pattern: (1-2-3-4) тЖТ (4-2-1-3) тЖТ (2-3-1-4), which maps BACK to KABC and then to ACBK.
In letter-based series questions, write down the numeric position (1,2,3,4) for each letter of the first word and map their new positions in the subsequent words to identify the mathematical rule quickly.
