This series is designed to help you step up your Data Sufficiency practice while we all spend a little extra time at home during the coronavirus situation; I’m going to publish one practice Data Sufficiency question each day! You can choose to do all of them, or none of them.

And remember to take whatever precautions you need to stay healthy over the next few weeks!

Question #4

Is q less than .30 ?

(1) q is less than 1/3.

(2) q is equal to 1/4.

Explanation

Statement (1) is insufficient, since q could still equal values that are either greater than (.32, for example) or less than .30. Since statement (2) gives us an exact value, we know it is sufficient to answer the question. (Hint: don’t worry about whether the answer is “yes” or “no;” the real trick is knowing that there IS an absolute answer.) The correct answer is (B).
