# Get acquainted with Data Sufficiency

Data sufficiency is a new beast that most of you would encounter for the first time during your GMAT prep.

The objective of Data Sufficiency (or DS) questions is not to find the actual values, rather, to figure out whether the given data is sufficient to answer the question.

A data sufficieny question would test your ability to:

- Analyze a quantitative problem
- figure out relevant information
- determine whether information is sufficient to solve the problem

A data sufficiency question on the GMAT would have 3 components:

- Question stem
- Two statements (data)
- Answer choices (5, always fixed)

A sample DS question:

What is the value of x?

1) 5 < x < 7

2) 3x = 18

- Statement (1) ALONE is sufficient, but statement (2) alone is not sufficient to answer the question asked.
- Statement (2) ALONE is sufficient, but statement (1) alone is not sufficient to answer the question asked.
- BOTH statements (1) and (2) TOGETHER are sufficient to answer the question asked, but NEITHER statement ALONE is sufficient to answer the question asked.
- EACH statement ALONE is sufficient to answer the question asked.
- Statements (1) and (2) TOGETHER are NOT sufficient to answer the question asked, and additional data specific to the problem are needed.

The answer to this question is: B (2nd answer choice).
