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.
What is the numerical code for ‘water’ in a certain code?
I. The code for ‘give me water’ is ‘719’.
II. The code for ‘you can bring water for me’ is ‘574186’.
Answer & explanation
Correct answer: option 4
The correct answer is Option (4) → Neither statement I nor statement II is sufficient, even together.
Each word has one digit, but the order of the digits need not follow the order of the words. A digit is fixed for a word only when that word alone is common to two codes.
Statement I alone:
‘water’ is one of 7, 1, 9: not sufficient
Statement II alone:
‘water’ is one of six digits: not sufficient
Both together:
Words common to both sentences: ‘me’ and ‘water’
Digits common to both codes: 7 and 1
‘water’ is 7 or 1, and nothing decides which: not sufficient even together
