Data sufficiency mini quiz (part II)

Last updated: 3 Mar 2007

In part I of the data sufficiency mini quiz we looked at each data statements in turn for the questions below.

Now we will look at the both statements together with each question.

Fill in the "Is 1 sufficient?" and "Is 2 sufficient?" columns with "yes" or "no" to indicate whether each data statement is sufficient to answer the question. If you can't remember what you answered previously then work it out again (it should not take you long).

Then fill in the "Answer" column with one of the the following GMAT answer choices.

1. Statement (1) ALONE is sufficient, but statement (2) alone is not sufficient
2. Statement (2) ALONE is sufficient, but statement (1) alone is not sufficient
3. BOTH statements TOGETHER are sufficient, but NEITHER statement ALONE is sufficient
4. EACH statement ALONE is sufficient
5. Statements (1) and (2) TOGETHER are NOT sufficient

If you have trouble remembering the answer choices then remember 1-2-TEN.

We have filled in the first row for you.

#	Question	Is 1 sufficient?	Is 2 sufficient?	Answer (A-E)
1	What percentage of R is S? `R/S = 24/25` `R + 3 = S`	Yes	No	A
2	Is `m/n` an integer? `m` is an even number `m` is a multiple of `n`
3	Is `x` an even number? `x^2` is even `x + 1` is odd
4	What is the value of a + b? b = 7 a - b = 12
5	Is `y` an odd number? `2y` is an even number `y` is divisible by 3

Try to answer these before continuing the tutorial.
