Read the information given below to answer the question that follows:
In a certain code language:
(i) 'pit na sa' means 'you are welcome'
(ii) 'na ho pa la' means 'they are very good'
(iii) 'ka da la' means 'who is good'
(iv) 'ho pit la' means 'they welcome good'
Which of the following means 'welcome' in that code language?
Answer & explanation
Correct answer: option 1
The correct answer is Option (1) → pit
A word that appears in two sentences has its code in both coded sentences, so the code for a word is the code word the two sentences share.
‘welcome’ is in (i) ‘you are welcome’ = ‘pit na sa’ and in (iv) ‘they welcome good’ = ‘ho pit la’
The only code word common to (i) and (iv) is pit, so pit = welcome
The other codes fit the same way: la is in (ii), (iii) and (iv), the three sentences with ‘good’, so la = good; pa occurs only in (ii) and stands for ‘very’; ‘od’ does not occur in any sentence.
