Question

The given question consists of a set of statements. Find out whether the data provided in the statements are sufficient to answer the question and mark the option:

What is the value of n
I. 3n + 2m = 18
II. n – m = 2n - (4+m)

• A. If Statement I alone is sufficient but Statement II alone is not sufficient to answer the question
• B. If Statement II alone is sufficient but Statement I alone is not Sufficient to answer the question
• C. If both statements taken together are sufficient to answer the question but neither statement alone is sufficient
• D. If statements I and II together are not sufficient and additional data is needed to answer the question
• E. If the data either in Statement I alone or Statement II alone are sufficient to answer the question

Answer 1

The correct option is B If Statement II alone is sufficient but Statement I alone is not Sufficient to answer the question

From Statement I, 3n + 2m = 18
From Statement II, n – m = 2n – (4 + m)
$\Rightarrow$ n – m = 2n – 4 – m
$\Rightarrow$ 2n – n = 4 + m – m $\Rightarrow$ n = 4
So, the value of n can be calcuted using Statement II
Alone but Statement I alone is not sufficient.
