In a certain code language, ‘house fire gas’ is coded as ‘dy ph mt’, ‘pressure gas station’ is coded as ‘lp ph st’, ‘station house farm’ is coded as ‘st bq dy’. What is the code for 'gas' in that language? (Note: All the codes are two-letter coded only.)
Correct Answer: D. ph
Explanation: The logic involves shifting each letter backward by 4 positions in the English alphabet: S (19) - 4 = O (15) K (11) - 4 = G (7) I (9) - 4 = E (5) B (2) - 4 = X (however, the pattern in the example SKIB to OGNG and CUCV to YQHA shows a consistent -4 shift for each letter, wrapping around the alphabet where necessary). Applying the -4 shift to QIRK: Q (17) - 4 = M (13) I (9) - 4 = E (5) R (18) - 4 = N (14) K (11) - 4 = G (7) However, looking at the provided options (MWEP, MWPE, MEPW, MEWP) and the second example CUCV to YQHA: C (3) - 4 = Y (25) U (21) - 4 = Q (17) C (3) - 4 = Y (actually H is +5) Re-evaluating the pattern: S to O is -4 K to G is -4 I to N is +5 B to G is +5 Applying this pattern (-4, -4, +5, +5) to QIRK: Q (17) - 4 = M I (9) - 4 = E R (18) + 5 = W K (11) + 5 = P Therefore, QIRK is related to MEWP.
