Welcome to GMAT Question of the Day! Before you get started I thought that I might make a few suggestions on how to approach these daily GMAT questions. If you just want to sign up for a challenging GMAT question emailed to you weekly go ahead and fill in this form:

Practice as you want to perform

1. Treat these questions as real GMAT practice. Try to solve them within 2 minutes (or so). Start training your inner sense of timing so that when you are taking the real test you know when you have to move on to the next question. Here is a more detailed break down of good GMAT study habits and GMAT Timing. These are both things that you want to get figured out early on – especially the study habits.

Thorough review does Not have to be an Exhausting review

2. Spend as much time as you need to review the question. This is the place to sit and contemplate. Still, try to keep your review of a single question to a max of 10 minutes. After that you might want to take a break and look at something else. Or just have a cup of tea and read the Economist. There’s no need to spin your wheels and burn yourself out on one of these questions. At this point you might just go ahead and ask for some assistance in the comments section. This will save you a lot of time and potentially help someone else who is having the same issue. Here is an article on reviewing impossible GMAT questions that might be helpful.

Be honest about Weaknesses

3. If you’re finding that a certain category of question of the day is consistently stumping you then it’s time to take a deeper look at that subject. You probably don’t have a good strategy for organizing the question type. Where can you find a good strategy? Great question. Not an easy one to answer. You can certainly start on the forums: GMAT Club, Beat the GMAT, and Manhattan GMAT Forum. You may have to wade through some slime but there is good information there. You can also find my GMAT QA here at Poets and Quants.

Q of the Day Conclusion

Have fun with these GMAT Questions of the day – make them a part of your ritual. Maybe you can do a question every morning with your cup of coffee and then if it’s a subject that you need to improve upon you can do a bit of reading on some strategy during your lunch break. Use these as learning tools. Over 3 months you’ll have done about 60 of these questions and probably covered every major GMAT topic. If you have honestly solved every one of these questions and followed up by reinforcing all of your weaknesses you will have taken a big step towards your GMAT and MBA goals.

One last GMAT Question of the Day tip

Here are a few links to some of other GMAT forums that do a GMAT question of the day. I avoid any non-official verbal questions but I think you can find some solid Quant practice from these sites.

GMAT Question of the Day – Data Sufficiency – Overlapping Sets

Of the leopards at a certain zoo, 20% are both spotted and mature. If all the leopards at the zoo are either spotted or not spotted, or mature or immature, is the ratio of the number of immature leopards who are spotted to the number of immature leopards who are not spotted greater than 1?

(1) If the number of immature spotted leopards doubled than there would be 102 total leopards at the zoo.

(2) If the number of immature but not spotted leopards were decreased by a half there would 86 total leopards at the zoo.

This overlapping sets question might leave you feeling a bit empty. Thinking – what was the point of that? Well, the point of that was to define the information that you were given and then to realize that you didn’t have enough to answer the questions. That’s what DS questions with an “E” answer are like. Sometimes there is no further meaning than just plain old insufficient.

GMAT Question of the Day Overlapping Sets Solution

More GMAT overlapping sets practice questions!

Here’s an overlapping sets question that adds in a bit of probability. Don’t let the probability component get in your way! Often, probability questions are easy. Take it step by step.

Among a group of 2,500 people, 35 percent invest in municipal bonds, 18 percent invest in oil stocks, and 7 percent invest in both municipal bonds and oil stocks. If 1 person is to be randomly selected from the 2,500 people, what is the probability that the person selected will be one who invests in municipal bonds but NOT in oil stocks?

Here’s a challenging sets question from the GMAT Prep Tests 1 and 2. Stay organized. Make the easy inferences and you should be fine.

In a certain city, 80 percent of the households have cable television, and 60 percent of the households have videocassette recorders. If there are 150,000 households in the city, then the number of households that have both cable television and videocassette recorders could be any number from:

Here’s one from GMAT Question of the Day that’s in the same vein. It also has percents/proportions and will give excellent practice using the two group overlapping sets matrix.

GMAT Question of the Day 2 group overlapping sets proportions and percents

This one is a bit different but will still give you 2 group practice and will give you exposure to overlapping sets on data sufficiency which often comes down to systems of questions/counting equations.

GMAT Question of the Day – Problem Solving – Percent

At the beginning of the year in town X, 30% of the population had liberal values. At the end of the year the total population had grown by 12% and the proportion of the population with liberal values had decreased by 5%. From the beginning of the year to the end of the year what was the approximate percent increase in the number of people in town x with non-liberal values?

A. 9%

B. 10%

C. 12%

D. 15%

E. 17%

GMAT Question of the Day Solution

Here comes another challenging GMAT word problem. In GMAT tutoring the lesson on word problems revolves around three things:

1. Taking the time to read and process before calculating

2. Defining the question

3. Looking for ways to simplify (reduce, factor, approximate)

In this case we are looking for the percent change (a GMAT subject that comes up pretty often) of the non-liberal population. We’re only given proportions so it might be helpful to pick some values. For this type of question you’ll generally be picking a value for the total population from which you’ll derive the rest of the values. There are some questions for which you’ll pick multiple values but that should be evident from the wording of the question. In percent questions a total that is a multiple of 100 tends to work pretty well.

It is super helpful to define what you are looking for. If you fail to do so this question could become and arithmetic nightmare. If you plan well, with one tiny approximation (moving 143 up to 145) you end up with a very clean result. If you were completely stuck you could do come educated guessing on this one. You know that the population went up 12% but that the increase in non-liberals was greater than the increase in liberals. So the increase in non-liberals must have been greater than 12%. That eliminates A, B, and C.
