Question

How is 'light' coded in the given code language?

I. 'more light than dark' is coded as '3 2 1 7' and 'no more dark here' is coded as '9 1 4 3'.

II. 'no more than that' is coded as '3 0 4 7' and 'no than and that' is coded as '4 5 0 7'.

• A. If the data in statement II alone is sufficient to answer the question, while the data in statement I alone is not sufficient to answer the question
• B. If the data either in statement I alone or in statement II alone are sufficient to answer the question
• C. If the data given in both statements I and II together are not sufficient to answer the question
• D. If the data in both statements I and II together are necessary to answer the question.

Answer 1

The correct option is D

If the data in both statements I and II together are necessary to answer the question.

From Statement I,

$\therefore$ light = 2/7

Hence, Statement I alone is insufficient.

Statement II alone is insufficient as light is not mentioned in it.

From Statements I and II,

$\therefore$ light = 2

So, both statements together are required to answer the question.
