PTOS is related to NRMQ in a certain way based on the English alphabetical order. In the same way, JNIM is related to HLGK. To which of the following is QUPT related, following the same logic?
OSNR
SORN
OSRN
SONR
OSNR
Apply a constant -2 alphabetical shift to each letter: P(16)-2=N(14), T(20)-2=R(18), O(15)-2=M(13), S(19)-2=Q(17).
Apply a constant -2 alphabetical shift to each letter: P(16)-2=N(14), T(20)-2=R(18), O(15)-2=M(13), S(19)-2=Q(17).
Analyze the transformation pattern
Compare PTOS to NRMQ: P(16) тЖТ N(14) is -2, T(20) тЖТ R(18) is -2, O(15) тЖТ M(13) is -2, S(19) тЖТ Q(17) is -2. The rule is consistently -2 for every position.
Verify with secondary pair
Compare JNIM to HLGK: J(10) тЖТ H(8) is -2, N(14) тЖТ L(12) is -2, I(9) тЖТ G(7) is -2, M(13) тЖТ K(11) is -2. The rule holds.
Apply logic to QUPT
Apply -2 to each letter: Q(17)-2=O(15), U(21)-2=S(19), P(16)-2=N(14), T(20)-2=R(18). This results in OSNR.
B: SORN is incorrect as it implies an incorrect sequence of letters; C: OSRN is incorrect due to a transposition error in the 3rd and 4th positions; D: SONR is incorrect as it fails to follow the -2 shift for the second letter.
A is correct because the pattern follows a consistent subtraction of 2 from the numerical position of each letter in the word, yielding Q-2=O, U-2=S, P-2=N, and T-2=R.
In coding-decoding questions, always write out the numerical values (A=1, B=2, ..., Z=26) immediately to reveal arithmetic patterns that are often invisible to the naked eye.
