The question below is followed by two statements numbered I and II. Decide whether the data given in the statements are sufficient to answer the question.
In a certain code language, each word is always written with the same code word, different words have different code words, and the code words need not be in the same order as the words. What is the code for ‘sky’?
I. ‘mo ti ra’ means ‘blue sky above’, and ‘ti ka’ means ‘sky high’.
II. ‘ra lu’ means ‘above all’, and ‘pe mo’ means ‘blue bird’.
Answer & explanation
Correct answer: option 1
The correct answer is Option (1) → Statement I alone is sufficient, but statement II alone is not sufficient.
A word that appears in two sentences takes the code word common to both codes. A code is found when one word and one code word are left together.
Statement I alone:
‘sky’ is the only word common to ‘blue sky above’ and ‘sky high’
‘ti’ is the only code word common to ‘mo ti ra’ and ‘ti ka’
So sky = ti: sufficient
Statement II alone:
The word ‘sky’ does not appear in either sentence, so its code cannot be found: not sufficient
