GMAT Data Sufficiency Questions With Answers<\/h1>\n

Data Sufficiency questions constitute a major chunk of the Quant section of the GMAT. Of the 31 questions that appear in this section, you can expect close to 50% of the questions from Data Sufficiency. In this article, we will be looking into 3 examples of GMAT Data Sufficiency Questions With Answers<\/p>\n

In case you do not have your basics of Data Sufficiency cleared, I highly recommend going over our other blog on GMAT Data Sufficiency strategy.<\/p>\n

Examples – GMAT Data Sufficiency Questions With Answers<\/h2>\n

Question 1:<\/h3>\n

Is xy < 6 ?<\/p>\n

Statement 1: x< 2, y<3<\/p>\n

Statement 2: x and y are non-negative<\/p>\n

a) Statement (1) ALONE is sufficient, but Statement (2) alone is not sufficient<\/span>
\n<\/span>b) Statement (2) ALONE is sufficient, but Statement (1) alone is not sufficient<\/span>
\n<\/span>c) Both Statements (1) and (2) TOGETHER are sufficient, but NEITHER statement ALONE is sufficient.<\/span>
\n<\/span>d) EACH statement ALONE is sufficient<\/span>
\n<\/span>e) Statements (1) and (2) TOGETHER are NOT sufficient<\/span><\/p>\n

Approach:<\/h3>\n

Let us consider Statement 1. If x < 2 and y < 3, then xy < 6. But this is only possible if we do not consider the sign.<\/p>\n

Imagine that one of them turns out to be negative, then irrespective of the other value, xy < 6.<\/p>\n

However, if both turn out to be negative, then xy can take any value as large as possible.<\/p>\n

Hence, Statement 1 is not sufficient.<\/p>\n

Statement 2 is again not sufficient since x and y can take any value.<\/p>\n

When we combine these statements, we know that x and y are either positive or zero. If any one or both are zero, xy < 6<\/p>\n

When none of them is zero, they are still less than 6.<\/p>\n

Hence, option C stating that both together are sufficient, however, none of them individually are sufficient is right.<\/p>\n

Question 2:<\/h3>\n

What is the radius of a circle C?<\/p>\n

Statement 1: The ratio of the circumference and the diameter = 3.14<\/p>\n

Statement 2: The ratio of the area and the circumference is 5.4 units.<\/p>\n

a) Statement (1) ALONE is sufficient, but Statement (2) alone is not sufficient<\/span>
\n<\/span>b) Statement (2) ALONE is sufficient, but Statement (1) alone is not sufficient<\/span>
\n<\/span>c) Both Statements (1) and (2) TOGETHER are sufficient, but NEITHER statement ALONE is sufficient.<\/span>
\n<\/span>d) EACH statement ALONE is sufficient<\/span>
\n<\/span>e) Statements (1) and (2) TOGETHER are NOT sufficient<\/span><\/p>\n

Approach:<\/h3>\n

Statement 1: Circumference = 2 * pi * r<\/p>\n

Diameter = 2 * r<\/p>\n

Approach:Ratio = pi<\/p>\n

The statement does not add any value to the information that is provided.<\/p>\n

Statement 2: The ratio of the area and the circumference is 5.4 units.<\/p>\n

pi * r * r \/ (2 * pi * r) = 5.4<\/p>\n

r = 10.8 units.<\/p>\n

Hence, Option B – Statement 1 alone is not sufficient, Statement 2 alone is sufficient is the correct choice.<\/p>\n

Question 3:<\/h3>\n

Is |x+y| > 5 ?
\nStatement 1: |2x| > 6
\nStatement 2: |y| > 2<\/p>\n

a) Statement (1) ALONE is sufficient, but Statement (2) alone is not sufficient<\/span>
\n<\/span>b) Statement (2) ALONE is sufficient, but Statement (1) alone is not sufficient<\/span>
\n<\/span>c) Both Statements (1) and (2) TOGETHER are sufficient, but NEITHER statement ALONE is sufficient.<\/span>
\n<\/span>d) EACH statement ALONE is sufficient<\/span>
\n<\/span>e) Statements (1) and (2) TOGETHER are NOT sufficient<\/span><\/p>\n

Approach:<\/h3>\n

Statement 1: |2x| > 6<\/p>\n

Hence, |x| > 3<\/p>\n

Statement 2: |y| > 2<\/p>\n

Now, for\u00a0 |x+y| > 5, we must satisfy the following condition:<\/p>\n

x + y < -5 or x + y > 5<\/p>\n

Now, using both hints we know that |x| > 3 and |y| > 2.<\/p>\n

If both x and y are negative, or both x and y are positive, we can definitely say that x + y > 5 or x + y < -5<\/p>\n

Hence, |x + y| > 5.<\/p>\n

But if one of them is positive and the other is negative, there can e several cases possible, if we can find out even a single case where |x + y| < 5, we can safely say that both the options together are not sufficient.<\/p>\n

Suppose x = 6 and y = -4, then |x+y| = 2, which is less than 5, hence, option E is the correct choice.<\/p>\n

Note:<\/h3>\n
