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.)
st
lp
mt
ph
ph
Compare Statement 1 and Statement 2. The word 'gas' is the only common word between 'house fire gas' and 'pressure gas station'. Similarly, 'ph' is the only common code between 'dy ph mt' and 'lp ph st'. Thus, 'gas' = 'ph'.
Compare Statement 1 and Statement 2. The word 'gas' is the only common word between 'house fire gas' and 'pressure gas station'. Similarly, 'ph' is the only common code between 'dy ph mt' and 'lp ph st'. Thus, 'gas' = 'ph'.
Analyze Statement 1 and Statement 2
Statement 1: 'house fire gas' = 'dy ph mt' Statement 2: 'pressure gas station' = 'lp ph st' Comparing both statements, the only word common to both is 'gas'. The only code common to both is 'ph'. Therefore, 'gas' is coded as 'ph'.
Cross-Verify with Statement 3 for Full Confirmation
Statement 3: 'station house farm' = 'st bq dy'
Final Conclusion
The word 'gas' uniquely maps to the code 'ph'.
A: 'st' is the code for 'station' (common between Statement 2 and Statement 3)., B: 'lp' is the code for 'pressure' (remaining code in Statement 2)., C: 'mt' is the code for 'fire' (remaining code in Statement 1).
D is correct because comparing Statement 1 and Statement 2 shows that 'gas' is the only common word and 'ph' is the only common code.
In substitutional coding questions, never solve for all words. Focus immediately on the target word by picking two statements where it appears, or eliminate other confirmed word-code pairs.
