Find which of the statements is/are sufficient to answer the given question.
What does 'Brown' represent in a code language?
(A) 'hiw ka tac' means 'Brown and Grey' in that code language.
(B) 'ma ta da' means 'you are Green' in that code language.
(C) 'ka da rac' means 'you can Brown' in that code language.
Answer & explanation
Correct answer: option 1
The correct answer is Option (1) → Only (A) and (C)
The code of a word is found by comparing two messages that share that word and no other: the code common to both is its code.
(A) and (C) share only the word ‘Brown’, and only ‘ka’ is common to their codes, so ka = Brown. These two are enough.
(A) and (B) share no word, so they cannot fix any code.
(B) and (C) share only ‘you’, so they fix da = you, but leave ‘ka’ and ‘rac’ open for ‘can’ and ‘Brown’.
Statement (B) adds nothing to (A) and (C), so only (A) and (C) are needed.
