Quantitative Aptitude (SBI-CL) Data Sufficiency

What is the sum of x and y?

Statement I: 15x + 4y = 108

Statement II: y = 27 – 3.75x

The data in statements I alone is sufficient to answer the question, while the data in statement II alone is not sufficient to answer the question.

The data in statements II alone is sufficient to answer the question, while the data in statement I alone is not sufficient to answer the question.

Either Statement I or Statement II alone is sufficient to answer the question.

The data in both the statements I and II is not sufficient to answer the question.

The data in both the statements I and II together is necessary to answer the question.

Explanation:

From the statement I, 15x + 4y = 108 ----- (i)
From the statement II, y = 27 – 3.75x
4y + 15x = 108 ----- (ii)
Here, both the equations are same it means we have two variable and one equation therefore we
could not conclude the value of two variable from one equation.
Therefore, the data in both the statements I and II is not sufficient to answer the question.
Hence, option D is correct.
